text: "Context. This paper investigates the star formation histories (SFHs) of a
sample of massive galaxies (M⋆ ≥ 1010 M⊙) in the redshift range 1 < z < 4.5.\r\nMethods.
We analyzed spectro-photometric data, combining broadband photometry from HST
and JWST with low-resolution grism spectroscopy from JWST/NIRISS, obtained as
part of the MIRI Deep Imaging Survey program. SFHs were derived through spectral
energy distribution fitting using two independent codes, BAGPIPES and synthesizer,
under various SFH assumptions. This approach enables a comprehensive assessment
of the biases introduced by different modeling choices.\r\nResults. The inclusion
of NIRISS spectroscopy, even with its low resolution, significantly improves constraints
on key physical parameters, such as the mass-weighted stellar age (tM) and formation
redshift (zform), by narrowing their posterior distributions. The massive galaxies
in our sample exhibit rapid stellar mass assembly, forming 50% of their mass between
3 ≤ z ≤ 9. The highest inferred formation redshifts are compatible with elevated
star formation efficiencies (ϵ) at early epochs. Nonparametric SFHs generally
imply an earlier and slower mass assembly compared to parametric forms, highlighting
the sensitivity of inferred formation timescales to the chosen SFH model–particularly
for galaxies at z < 2. We find that quiescent galaxies are, on average, older
(tM ∼ 1.1 Gyr) and assembled more rapidly at earlier times than their star-forming
counterparts. These findings support the “downsizing” scenario, in which more
massive and passive systems form earlier and more efficiently."

text: Ionized proximity zones around luminous quasars provide a unique laboratory
to characterize the Lyα emission lines from z > 6 galaxies without significant
attenuation from the intergalactic medium (IGM). However, Lyα line measurements
for galaxies within high-redshift quasars’ proximity zones have been rare so far.
Here we present deep spectroscopic observations obtained with the NIRSpec/Micro-Shutter
Assembly (MSA) instrument on the James Webb Space Telescope of galaxies in two
z > 6 quasar fields. We measure the Lyα line fluxes for 50 galaxies at 6 < z <
7 with UV absolute magnitude M UV < −19 (median M UV = −19.97), among which 15
are located near the luminous quasars, i.e., within Δv < 2500 km s−1. We find
that galaxies near the quasars show significant flux blueward of the systemic
Lyα wavelength, and have higher Lyα equivalent width compared to galaxies at similar
redshifts that are not located within the quasars’ environment. Our result indicates
little or no redshift evolution for the Lyα emitter fraction from z ∼ 6.4 to z
∼ 5. Leveraging the low IGM opacity in the quasars’ vicinity, we evaluate the
Lyα escape fraction (f esc Ly α) of high-redshift galaxies. Our analysis suggests
that galaxies at 〈z〉 ≈ 6.4 have an average f esc Ly α = 0.14 ± 0.04. This value
is consistent with reionization models where the Lyman continuum escape fraction
is low ( fescLyC ≲ 0.1 ) for luminous galaxies, and where the most luminous galaxies
have only a minor contribution to the total ionizing photon budget. © 2025. The

text: "We used observations from the JWST Emission Line Survey (JELS) to measure
the half-light radii (re) of 23 Hα-emitting starforming (SF) galaxies at z = 6.1
in the PRIMER/COSMOS field. Galaxy sizes were measured in JWST near-infrared camera
observations in rest-frame Hα (tracing recent star formation) with the F466N and
F470N narrow-band filters from JELS, and\r\ncompared against rest-R- and V -band
(tracing established stellar populations) and near-ultraviolet sizes. We find
a size–stellar mass(re − M∗) relationship with a slope that is consistent with
literature values at lower redshifts, though offset to lowersizes. We observe
a large scatter in re at low stellar mass (M∗ < 10^8.4 Mo) which we believe is
the result of bursty star formation histories (SFHs) of SF galaxies at the Epoch
of Reionization (EoR). We find that the stellar and ionized gas components are
similar in size at z = 6.1. The evidence of already-established stellar components
in these Hα emitters (HAEs) indicates previous episodes of star formation have
occurred. As such, following other JELS studies finding our HAEs are undergoing
a current burst of star formation, we believe our results indicate that SF galaxies
at the end of the EoR have already experienced a bursty SFH. From our re − M∗
relationship, we find re,F444W = 0.76 ± 0.46 kpc for fixed stellar mass M∗ = 10^9.25
M, which is in agreement with other observations and simulations of SF galaxies
in the literature. We find a close-pair (major) merger fraction of (fmaj. merger
=0.44 ± 0.22) fmerger = 0.43 ± 0.11 for galaxy separations d <~ 25 kpc, which
is in agreement with other z ≈ 6 studies."

text: "We analyse James Webb Space Telescope (JWST) Near Infrared Imager and Slitless
Spectrograph (NIRISS) and Near Infrared Spectrograph (NIRSpec) spectroscopic observations
in the Abell 2744 galaxy cluster field. From approximately 120 candidates, we
identify 12 objects with at least two prominent emission lines among [O II] λ3727,
H β λ4861, [O III] λ4959, [O III] λ5007, and H α λ6563 that are spectroscopically
confirmed by both instruments. Our key findings reveal systematic differences
between the two spectrographs based on source morphology and shutter aperture
placement. Compact objects show comparable or higher\r\nintegrated flux in NIRSpec
relative to NIRISS (within 1σ uncertainties), while extended sources consistently
display higher flux in NIRISS measurements. This pattern reflects NIRSpec’s optimal
coverage for compact objects while potentially undersampling extended sources.
Quantitative analysis demonstrates that NIRSpec recovers at least 63 per cent
of NIRISS-measured flux when the slit covers >15 per cent of the source or when
Re < 1 kpc. For lower coverage or larger effective radii, the recovered flux varies
from 24 per cent to 63 per cent. When studying the H α λ6563/[O III] λ5007 emission
line ratio, we observe that\r\nmeasurements from these different spectrographs
can vary by up to ∼0.3 dex, with significant implications for metallicity and
star formation rate characterizations for individual galaxies. These results highlight
the importance of considering instrumental effects when combining multi-instrument
spectroscopic data and demonstrate that source morphology critically influences
flux\r\nrecovery between slit-based and slitless spectroscopic modes in JWST observations."

text: "Context. One of the surprising early findings with JWST has been the discovery
of a strong “roll-over” or a softening of the absorption edge of Lyα in a large
number of galaxies at z ≳ 6, in addition to systematic offsets from photometric
redshift estimates and fundamental galaxy scaling relations. This has been interpreted
as strong cumulative damped Lyα absorption (DLA) wings from high column densities
of neutral atomic hydrogen (H I), signifying major gas accretion events in the
formation of these galaxies.\r\nAims. To explore this new phenomenon systematically,
we assembled the JWST/NIRSpec PRImordial gas Mass AssembLy (PRIMAL) legacy survey
of 584 galaxies at z = 5.0 − 13.4, designed to study the physical properties and
gas in and around galaxies during the reionization epoch.\r\nMethods. We characterized
this benchmark sample in full and spectroscopically derived the galaxy redshifts,
metallicities, star formation rates, and ultraviolet (UV) slopes. We defined a
new diagnostic, the Lyα damping parameter DLyα, to measure and quantify the net
effect of Lyα emission strength, the H I fraction in the intergalactic medium,
or the local H I column density for each source. The JWST-PRIMAL survey is based
on the spectroscopic DAWN JWST Archive (DJA-Spec). We describe DJA-Spec in this
paper, detailing the reduction methods, the post-processing steps, and basic analysis
tools. All the software, reduced spectra, and spectroscopically derived quantities
and catalogs are made publicly available in dedicated repositories.\r\nResults.
We find that the fraction of galaxies showing strong integrated DLAs with NHI > 1021 cm−2
only increases slightly from ≈60% at z ≈ 6 up to ≈65 − 90% at z > 8. Similarly,
the prevalence and prominence of Lyα emission is found to increase with decreasing
redshift, in qualitative agreement with previous observational results. Strong
Lyα emitters (LAEs) are predominantly found to be associated with low-metallicity
and UV faint galaxies. By contrast, strong DLAs are observed in galaxies with
a variety of intrinsic physical properties, but predominantly at high redshifts
and low metallicities.\r\nConclusions. Our results indicate that strong DLAs likely
reflect a particular early assembly phase of reionization-era galaxies, at which
point they are largely dominated by pristine H I gas accretion. At z = 8 − 10,
this gas gradually cools and forms into stars that ionize their local surroundings,
forming large ionized bubbles and producing strong observed Lyα emission at z < 8."

text: "We present a sample of 1956 individual stellar clumps at redshift 0.7 < z
< 10, detected with JWST/NIRCam in 476 galaxies lensed by the galaxy cluster Abell2744.
The lensed clumps present magnifications ranging between μ = 1.8 and μ = 300.
We perform simultaneous size-photometry estimates in 20 JWST/NIRCam median and
broad-band filters from 0.7 to 5 μm.\r\nSpectral energy distribution (SED) fitting
analyses enable us to recover the physical properties of the clumps. The majority
of the clumps are spatially resolved and have effective radii in the range Reff
= 10–700 pc. We restrict this first study to the 1751 post-reionization era clumps
with redshift < 5.5. We find a significant evolution of the average clump ages,
star formation rates (SFRs), SFR surface densities, and metallicity with increasing
redshift, while median stellar mass and stellar mass surface densities are similar
in the probed redshift range. We observe a strong correlation between the clump
properties and the properties of their host galaxies, with more massive galaxies
hosting more massive and older clumps. We find that clumps closer to their host
galactic centre are on average more massive, while their ages do not show clear
sign of migration. We find that clumps at cosmic noon sample the upper-mass end
of the mass function to higher masses than at z > 3, reflecting the rapid increase
towards the peak of the cosmic star formation history. We conclude that the results
achieved over the studied redshift range are in agreement with expectation of
in situ clump formation scenario from large-scale disc fragmentation. "

text: "Context. The hydrogen Lyman-alpha (Lyα) line, the brightest rest-frame ultraviolet
line of high-redshift galaxies, exhibits a large variety of shapes, which is due
to factors at different scales, from the interstellar medium to the intergalactic
medium (IGM).\r\nAims. The aim of this work is to provide a systematic inventory
and classification of the spectral shapes of Lyα emission lines to better understand
the general population of high-redshift Lyα emitting galaxies (LAEs).\r\nMethods.
Using the unprecedentedly deep data from the MUSE eXtremely Deep Field (MXDF;
up to 140 hour exposure time), we selected 477 galaxies observed in the ∼2.8−6.6
redshift range, 15 of which have a systemic redshift from nebular lines. We developed
a method to classify Lyα emission lines in four spectral and three spatial categories
by combining a pure spectral analysis with a narrow-band image analysis. We measured
spectral properties, such as the peak separation and the blue-to-total flux ratio
for the double-peaked galaxies.\r\nResults. To ensure a robust sample for statistical
analysis, we define two unbiased subsets, inclusive and restrictive, by applying
thresholds for signal-to-noise ratio, peak separation, and Lyα luminosity, yielding
a final unbiased sample of 206 galaxies. Our analysis reveals that between 32%
and 51% of the galaxies exhibit double-peaked profiles, with peak separations
ranging from 150 km s−1 to nearly 1600 km s−1. The fraction of double-peaked galaxies
seems to evolve dependently with the Lyα luminosity, while we do not see a severe
decrease in this fraction with redshift, which is expected given the IGM attenuation
at high redshift. An artificial increase in the number of double-peaked galaxies
at the highest redshifts may cause the observation of a plateau instead of a decrease.
A notable number of these double-peaked profiles show blue-dominated spectra,
suggesting unique gas dynamics and inflow characteristics in some high-redshift
galaxies. The consequent fraction of blue-dominated spectra needs to be confirmed
by obtaining new systemic redshift measurements. Among the double-peaked galaxies,
4% are spurious detections, that is, the blue and red peaks do not come from the
same spatial location. Around 20% out of the 477 sources of the parent sample
lie in a complex environment, meaning there are other clumps or galaxies at the
same redshift within a distance of 30 kpc.\r\nConclusions. Our results suggest
that the double-peaked LAE fraction may trace the evolution of IGM attenuation,
but the faintest galaxies must be observed at high redshift. We also need more
data to confirm the trend seen at low redshift. In addition, it is crucial to
obtain secure systemic redshifts for LAEs to better constrain the nature of the
Lyα double-peaked lines. Statistical samples of double-peaked and triple-peaked
galaxies are a promising probe of the evolution of the physical properties of
galaxies across cosmic time."

text: "Context. Recent observations suggest a significant and rapid buildup of dust
in galaxies at high redshift (z > 4); this presents new challenges to our understanding
of galaxy formation in the early Universe. Although our understanding of the physics
of dust production and destruction in a galaxy’s interstellar medium (ISM) is
improving, investigating the baryonic processes in the early universe remains
a complex task owing to the inherent degeneracies in cosmological simulations
and chemical evolution models.\r\nAims. In this work we characterized the evolution
of 98 z ∼ 5 star-forming galaxies observed as part of the ALMA Large Program ALPINE
by constraining the physical processes underpinning the gas and dust production,
consumption, and destruction in their ISM.\r\nMethods. We made use of chemical
evolution models to simultaneously reproduce the observed dust and gas content
of our galaxies, obtained respectively from spectral energy distribution (SED)
fitting and ionized carbon measurements. For each galaxy we constrained the initial
gas mass, gas inflows and outflows, and efficiencies of dust growth and destruction.
We tested these models with both the canonical Chabrier and a top-heavy initial
mass function (IMF); the latter allowed rapid dust production on shorter timescales.\r\nResults.
We successfully reproduced the gas and dust content in most of the older galaxies
(≳600 Myr) regardless of the assumed IMF, predicting dust production primarily
through Type II supernovae (SNe) and no dust growth in the ISM, as well as moderate
inflow of primordial gas. In the case of intermediate-age galaxies (300−600 Myr),
we reproduced the gas and dust content through Type II SNe and dust growth in
ISM, though we observed an overprediction of dust mass in older galaxies, potentially
indicating an unaccounted dust destruction mechanism and/or an overestimation
of the observed dust masses. The number of young galaxies (≲300 Myr) reproduced,
increases for models assuming top-heavy IMF but with maximal prescriptions of
dust production. Galactic outflows are required (up to a mass-loading factor of
2) to reproduce the observed gas and dust mass, and to recover the decreasing
trend of gas and dust over stellar mass with age. Assuming the Chabrier IMF, models
are able to reproduce ∼65% of the total sample, while with top-heavy IMF the fraction
increases to ∼93%, alleviating the tension between the observations and the models.
Observations from the James Webb Space Telescope (JWST) will allow us to remove
degeneracies in the diverse intrinsic properties of these galaxies (e.g., star
formation histories and metallicity), thereby refining our models."

text: The Hα nebular emission line is an optimal tracer for recent star formation
in galaxies. With the advent of JWST, this line has recently become observable
at z > 3 for the first time. We present a catalog of 1050 Hα emitters at 3.7 < z < 6.7
in the GOODS fields obtained from a blind search in JWST NIRCam/grism data. We
made use of the FRESCO survey’s 124 arcmin2 of observations in GOODS-North and
GOODS-South with the F444W filter, probing Hα at 4.9 < z < 6.7, and the CONGRESS
survey’s 62 arcmin2 of observations in GOODS-North with F356W, probing Hα at 3.8 < z < 5.1.
We found an overdensity with 98 sources at z ∼ 4.4 in GOODS-N, and confirmed previously
reported overdensities at z ∼ 5.2 in GOODS-N and at z ∼ 5.4 and z ∼ 5.9 in GOODS-S.
We computed the observed Hα luminosity functions (LFs) in three bins centered
at z ∼ 4.45, 5.30, and 6.15, which are the first such measurements at z > 3 obtained
based purely on spectroscopic data, robustly tracing galaxy star formation rates
(SFRs) beyond the peak of the cosmic star formation history. We compared our results
with theoretical predictions from three different simulations and found good agreement
at z ∼ 4 − 6. The UV LFs of this spectroscopically confirmed sample are in good
agreement with pre-JWST measurements obtained with photometrically selected objects.
Finally, we derived SFR functions and integrated them to compute the evolution
of the cosmic SFR densities across z ∼ 4 − 6, finding values in good agreement
with recent UV estimates from Lyman-break galaxies, which imply a continuous decrease
in SFR density by a factor of three over z ∼ 4 to z ∼ 6. Our work shows the power
of NIRCam grism observations to efficiently provide new tests for early galaxy
formation models based on emission line statistics.

text: We present a comprehensive analysis of H i absorption around 96 Lyα emitters
(LAEs) at z ≈ 3.3 (median Lyα luminosity ≈1042 erg s−1). These LAEs were identified
within eight MUSE fields, each (math. formular) on the sky and centered on a bright
background quasar, as part of the MUSEQuBES survey. Using Voigt profile fitting
for all H i absorbers detected within ±500 km s−1 of these LAEs, we compiled
a catalog of 800 H i absorption components. Our analysis shows that H i absorption
is enhanced near the LAEs compared to the intergalactic medium. However, no trend
is found between the column densities of H i absorbers and their impact parameters
from the LAEs (spanning ≈54–260 pkpc). Additionally, all galaxies associated
with Lyman-limit systems have impact parameters >50 pkpc from the quasar sightlines,
suggesting that true absorber hosts may be too faint to detect. The LAEs show
an overall H i covering fraction (fc(H i)) of ≈88% for a threshold (math. formular)
(H i) = 15. Notably, at the same threshold, the LAEs in pairs/groups exhibit a
100% H i covering fraction out to ≈250 pkpc. In contrast, isolated LAEs consistently
show a lower fc(H i) of ≈80%. This environmental influence on fc(H i) is also
evident up to ≈300 km s−1 in differential bins of line-of-sight velocity. We find
an anticorrelation between fc(H i) and the equivalent width of rest-frame Lyα
emission (EW0). Based on the Lyα shell model, this could imply that gas-rich galaxies
tend to reside in gas-rich environments or that the LAEs with higher EW0 are more
efficient at ionizing their surrounding medium.

the first few billion years of the Universe. The early disks detected so far,
with typical half-light radii of 3 kpc at stellar masses around 1011 M⊙ for redshift
z ≈ 3, are significantly smaller than today’s disks with similar masses, which
is in agreement with expectations from current galaxy models. Here we report observations
of a giant disk at z = 3.25, when the Universe was only two billion years old,
with a half-light radius of 9.6 kpc and stellar mass of (math formular). This
galaxy is larger than any other kinematically confirmed disks at similar epochs
and is surprisingly similar to today’s largest disks with regard to size and mass.
James Webb Space Telescope imaging and spectroscopy reveal its spiral morphology
and a rotational velocity consistent with a local Tully–Fisher relationship. Multiwavelength
observations show that it lies in an exceptionally dense environment, where the
galaxy number density is more than ten times higher than the cosmic average and
mergers are frequent. The discovery of such a giant disk suggests the presence
of favourable physical conditions for large-disk formation in dense environments
in the early Universe, which may include efficient accretion of gas carrying coherent
angular momentum and non-destructive mergers between exceptionally gas-rich progenitor
galaxies.

text: "We report the spectroscopic discovery of a massive quiescent galaxy at zspec
= 7.29 ± 0.01, just ∼700 Myr after the big bang. RUBIES-UDS-QG-z7 was selected
from public JWST/NIRCam and MIRI imaging from the PRIMER survey and observed with
JWST/NIRSpec as part of RUBIES. The NIRSpec/PRISM spectrum reveals one of the
strongest Balmer breaks observed thus far at z > 6, with no emission lines but
tentative Balmer and Ca absorption features, as well as a Lyman break. Simultaneous
modeling of the NIRSpec/PRISM spectrum and NIRCam and MIRI photometry (spanning
0.9–18 μm) shows that the galaxy formed a stellar mass of\r\n(math. formular)
before z ∼ 8 and ceased forming stars 50–100 Myr prior to the time of observation,
resulting in log (sSFR/Gyr- 1) < -1 . We measure a small physical size of (math
formular) , which implies a high stellarmass surface density within the effective
radius of (math formular) comparable to the highest densities measured in quiescent
galaxies at z ∼ 2–5. The 3D stellar-mass density profile of RUBIES-UDS-QG-z7 is
remarkably similar to the central densities of local massive ellipticals, suggesting
that at least some of their cores may have already been in place at z > 7. The
discovery of RUBIES-UDS-QG-z7 has strong implications for galaxy formation models:
the estimated number density of quiescent galaxies at z ∼ 7 is >100 × larger than
predicted from any model to date, indicating that quiescent galaxies have formed
earlier than previously expected. "

text: The JWST discovery of "little red dots" (LRDs) is reshaping our picture of
the early Universe, yet the physical mechanisms driving their compact size and
UV-optical colors remain elusive. Here, we report an unusually bright LRD (zspec
= 3.1) observed as part of the RUBIES program. This LRD exhibits broad emission
lines (FWHM ∼ 4000 km s−1), a blue UV continuum, a clear Balmer break, and a red
continuum sampled out to rest-frame 4 μm with MIRI. We develop a new joint galaxy
and active galactic nucleus (AGN) model within the Prospector Bayesian inference
framework and perform spectrophotometric modeling using NIRCam, MIRI, and NIRSpec/Prism
observations. Our fiducial model reveals a M* ∼ 109 M⊙ galaxy alongside a dust-reddened
AGN driving the optical emission. Explaining the rest-frame optical color as a
reddened AGN requires AV ≳ 3, suggesting that a great majority of the accretion
disk energy is reradiated as dust emission. Yet, despite clear AGN signatures,
we find a surprising lack of hot torus emission, which implies that either the
dust emission in this object must be cold, or the red continuum must instead be
driven by a massive, evolved stellar population of the host galaxy—seemingly inconsistent
with the high-EW broad lines (Hα rest-frame EW ∼ 800 Å). The widths and luminosities
of Pa-β, Pa-δ, Pa-γ, and Hα imply a modest black hole mass of MBH ∼ 108 M⊙. Additionally,
we identify a narrow blueshifted He i λ 1.083 μm absorption feature in NIRSpec/G395M
spectra, signaling an ionized outflow with kinetic energy up to ∼1% the luminosity
of the AGN. The low redshift of RUBIES-BLAGN-1, combined with the depth and richness
of the JWST imaging and spectroscopic observations, provides a unique opportunity
to build a physical model for these so-far mysterious LRDs, which may prove to
be a crucial phase in the early formation of massive galaxies and their supermassive
black holes.

text: Identifying Lyman continuum (LyC) leakers at intermediate redshifts is crucial
for understanding the properties of cosmic reionizers because the opacity of the
intergalactic medium (IGM) prevents the direct detection of LyC emission from
sources during the Epoch of Reionization (EoR). In this study, we confirm two
new LyC candidate leakers at z ∼ 3 in the Abell 2744 cluster field, with absolute
escape fractions (fesc) of 0.83−0.80+0.15 and 0.74−0.70+0.23, respectively. The
LyC emission was detected using HST/WFC3/F275W and F336W imaging. These two candidate
leakers appear to be faint (MUV = −17.61 ± 0.06 and −18.22 ± 0.10), exhibit blue
UV continuum slopes (β = −2.43 ± 0.05 and −1.92 ± 0.09), have low masses (M★ ∼ 107.51 ± 0.03
and 107.17 ± 0.15 M⊙) and Lyα equivalent widths of 90 ± 3 Å and 28 ± 12 Å, respectively.
These two LyC candidate leakers were detected in a catalog of 91 spectroscopically
confirmed sources using public spectra from the JWST and/or MUSE. We also analyzed
properties that were proposed as indirect indicators of LyC emission, such as
Lyα, the O32 ratio, and M★. We created a galaxy subsample that was selected according
to these properties, stacked the LyC observations of this subsample, and assessed
the limits of the escape fractions in the stacks. We aim to enhance our understanding
of LyC escape mechanisms and improve our predictions of the LyC fesc during the
EoR by analyzing the individual candidates and the stacks in the context of the
currently limited sample of known LyC leakers at z ∼ 3.

text: Among the most puzzling early discoveries of JWST are “little red dots” (LRDs),
compact red sources that host broad Balmer emission lines, and in many cases exhibit
a “V-shaped” change in slope in the rest-optical. The physical properties of LRDs
currently have order-of-magnitude uncertainties, because models to explain the
continuum of these sources differ immensely. Here, we leverage the complete selection
of red sources in the RUBIES program, supplemented with public PRISM spectra,
to study the origin of this V shape. By fitting a broken power law with a flexible
inflection point, we find that a large fraction of red Hα emitters at 2 < z <
6 exhibit a strong change in slope, and that all strong inflections appear associated
with the Balmer limit (0.3645 μm). Using a simple model of a reddened active galactic
nucleus (AGN) with an unobscured scattered-light component, we demonstrate that
the observed V shape in LRDs is unlikely to occur at any specific wavelength if
the entire continuum is dominated by light from a power-law AGN continuum. In
contrast, models with an intrinsic feature at the Balmer limit, such as those
that are dominated by an evolved stellar population, can produce the observed
spectral shapes, provided that a reddened component picks up sufficiently redward
of the break. While no model can comfortably explain the full LRD spectral energy
distribution, the common inflection location suggests that a single component
consistently dominates the rest-frame UV optical in LRDs, and that this component
is associated with T ∼ 10^4 K hydrogen.

text: Luminous broad Hα emission and red rest-optical spectral energy distributions
(SEDs) are the hallmark of compact little red dots (LRDs), implying highly attenuated
dusty starbursts and/or obscured active galactic nuclei (AGN). However, the lack
of observed far-infrared (FIR) emission has proved difficult to reconcile with
the implied attenuated luminosity in these models. Here, we utilize deep new Atacama
Large Millimeter/submillimeter Array imaging, new and existing JWST/MIRI imaging,
and archival Spitzer/Herschel imaging of two of the rest-optically brightest LRDs
(z = 3.1 and z = 4.47) to place the strongest constraints on the IR luminosity
in LRDs to date. The detections at λrest = 1–4 μm imply flat slopes in the rest-IR,
ruling out a contribution from hot (T ≳ 500 K) dust. Similarly, FIR nondetections
rule out any appreciable cold (T ≲ 75 K) dust component. Assuming energy balance,
these observations are inconsistent with the typical FIR dust emission of dusty
starbursts and quasar tori, which usually show a mixture of cold and hot dust.
Additionally, our [C ii] nondetections rule out typical dusty starbursts. We compute
empirical maximum IR SEDs and find that both LRDs must have log(LIR/L ) 12.2 at
the 3σ level. These limits are in tension with the predictions of rest-optical
spectrophotometric fits, be they galaxy-only, AGN-only, or composite. It is unlikely
that LRDs are highly dust-reddened intrinsically blue sources with a dust temperature
distribution that conspires to avoid current observing facilities. Rather, we
favor an intrinsically redder LRD SED model that alleviates the need for strong
dust attenuation.

text: "Compact, star-forming galaxies with high star formation rate surface densities
(ΣSFR) are often efficient Lyman continuum (LyC) emitters at z ≤ 4.5, likely because
intense stellar feedback creates low-density channels that allow photons to escape.
Irregular or disturbed morphologies, such as those resulting from mergers, can
also facilitate LyC escape by creating anisotropic gas distributions. We investigated
the influence of galaxy morphology on LyC production and escape at redshifts 5
≤ z ≤ 7 using observations from various James Webb Space Telescope (JWST) surveys.
Our sample consists of 436 sources, which are predominantly low-mass (∼10^8.15
M\f), star-forming galaxies with ionizing photon efficiency (ξion) values consistent
with canonical expectations. Since direct measurements of fesc are not possible
during the Epoch of Reionization (EoR), we predicted fesc for high-redshift galaxies
by applying survival analysis to a subsample of LyC emitters from the Low-Redshift
Lyman Continuum Survey (LzLCS), selected to be direct analogs of reionization-era
galaxies. We find that these galaxies exhibit, on average, modest predicted escape
fractions (∼0.04). In addition, we evaluated the correlation between morphological
features and LyC emission. Our findings indicate that neither ξion nor the predicted
fesc values show a significant correlation with the presence of merger signatures.
This suggests that in low-mass galaxies at z ≥ 5, strong morphological disturbances
are not the primary mechanism driving LyC emission and leakage. Instead, compactness
and star formation activity likely play a more pivotal role in regulating LyC
escape. "

text: 'Detecting the first generation of stars, Population III (Pop III), has been
a long-standing goal in astrophysics, yet they remain elusive even in the JWST
era. Here we present a novel NIRCam-based selection method for Pop III galaxies,
and carefully validate it through completeness and contamination simulations.
We systematically search ≃ 500 arcmin2 across JWST legacy fields for Pop III candidates,
including GLIMPSE, which, assisted by gravitational lensing, has produced JWST’s
deepest NIRCam imaging thus far. We discover one promising Pop III galaxy candidate
(GLIMPSE-16043) at z=6.50 -0.24 +0.03, a moderately lensed galaxy (µ = + 2.9 -0.2
+0.1) with an intrinsic UV magnitude of MUV= -15.89 -0.14 +0.12. It exhibits key
Pop III features: strong Hα emission (rest-frame EW 2810 ± 550 Å); a Balmer jump;
no dust (UV slope β = −2.34 ± 0.36); and undetectable metal lines (e.g., [O III];
[O III]/Hβ < 0.44), implying a gas-phase metallicity of Zgas/Z⊙ < 0.5%. These
properties indicate the presence of a nascent, metal-deficient young stellar population
(<5 Myr) with a stellar mass of ≃105 M⊙. Intriguingly, this source deviates significantly
from the extrapolated UV–metallicity relation derived from recent JWST observations
at z = 4–10, consistent with UV enhancement by a top-heavy Pop III initial mass
function or the presence of an extremely metal-poor active galactic nucleus. We
also derive the first observational constraints on the Pop III UV luminosity
function at z ≃ 6–7. The volume density of GLIMPSE-16043 (≈10^−4 cMpc−3) is in
excellent agreement with theoretical predictions, independently reinforcing its
plausibility. This study demonstrates the power of our novel NIRCam method to
finally reveal distant galaxies even more pristine than the Milky Way’s most metal-poor
satellites, thereby promising to bring us closer to the first generation of stars
than we have ever been before.'

text: JWST observations have unveiled faint active galactic nuclei (AGNs) at high
redshift that provide insights into the formation of supermassive black holes
(SMBHs). However, disentangling their stellar from AGN light is challenging. Here,
we use an empirical approach to infer the average stellar mass of five faint broad-line
(BL) Hα emitters at z = 4–5 with BH masses ≈6 × 10^6 M⊙, with a method independent
of their spectral energy distribution (SED). We use the deep JWST/NIRcam grism
survey “All the Little Things” to measure the overdensities around BL-Hα emitters
and around a spectroscopic reference sample of ∼300 galaxies. In our reference
sample, we find that megaparsec-scale overdensity correlates with stellar mass.
Their large-scale environments suggest that BL-Hα emitters are hosted by galaxies
with stellar masses ≈5 × 10^7 M⊙, ≈40 times lower than those inferred from galaxy-only
SED fits. Adding measurements around more luminous z ≈ 6 AGNs, we find tentative
correlations between line width, BH mass, and the overdensity, suggestive of a
steep BH to halo mass relation. The main implications are (1) when BH masses are
taken at face value, we confirm extremely high BH to stellar mass ratios of ≈10%,
(2) the galaxies of low stellar mass that host growing SMBHs are in tension with
typical hydrodynamical simulations, except those without feedback, (3) a 1% duty
cycle implied by the host mass hints at super-Eddington accretion, (4) the masses
are at odds with an interpretation of the line broadening in terms of high stellar
density, (5) our results imply a luminosity-dependent diversity of galaxy masses,
environments, and SEDs among AGN samples.

text: "We report the detection of a 13σ Hα emission line from HDF850.1 at z = 5.188
± 0.001 using the FRESCO (First Reionization Era SpectroscopicallyComplete Observations)
NIRCam F444W grism observations. Detection of Hα in HDF850.1 is noteworthy, given
its high far-infrared (IR) luminosity, substantial dust obscuration, and the historical
challenges in deriving its redshift.\r\nHDF850.1 shows a clear detection in the
F444W imaging data, distributed between a northern and southern component, mirroring
that seen in [C II] from the Plateau de Bure Interferometer. Modelling the spectral
energy distribution of each component separately, we find that the northern component
has a higher mass, star formation rate (SFR), and dust extinction than the southern
component. The observed Hα emission appears to arise entirely from the less-obscured
southern component and shows a similar \x04v∼ + 130 km s −1 velocity offset to
that seen for [C II] relative to the source systemic redshift. Leveraging Hα-derived
redshiftsfrom FRESCO observations, we find that HDF850.1 isforming in one of the
richest environments identified to date at z > 5, with 100 z = 5.17–5.20 galaxies
distributed across 13 smaller structures and a ∼(15 cMpc)3 volume. Based on the
evolution of analogous structures in cosmological simulations, the z = 5.17–5.20
structures seem likely to collapse into\r\na single > 1014M cluster by z ∼ 0.
Comparing galaxy properties forming within this overdensity with those outside,
we find the masses, SFRs, and UV luminosities inside the overdensity to be clearly
higher. The prominence of Hα line emission from HDF850.1 and other known highly
obscured z > 5 galaxies illustrates the potential of NIRCam-grism programs to
map both\r\nthe early build-up of IR-luminous galaxies and overdense structures."
