text: Stellar-mass black holes (BHs) are predicted to be embedded in the disks of
active galactic nuclei (AGNs) due to gravitational drag and in situ star formation.
However, clear evidence for AGN disk-embedded BHs is currently lacking. Here,
as possible electromagnetic signatures of these BHs, we investigate breakout emission
from shocks emerging around Blandford–Znajek jets launched from accreting BHs
in AGN disks. We assume that most of the highly super-Eddington flow reaches the
BH and produces a strong jet, and the jet produces feedback that shuts off accretion
and thus leads to episodic flaring. These assumptions, while poorly understood
at present, yield observable consequences that can probe the presence of AGN-embedded
BHs as well as the accretion process itself. They predict a breakout emission
characterized by luminous thermal emission in the X-ray bands and bright broadband
nonthermal emission from the infrared to the gamma-ray bands. The flare duration
depends on the BH's distance r from the central supermassive BH, varying between
103–106 s for r ∼ 0.01–1 pc. This emission can be discovered by current and future
infrared, optical, and X-ray wide-field surveys and monitoring campaigns of nearby
AGNs.

text: The astrophysical origin of over 90 compact binary mergers discovered by the
LIGO and Virgo gravitational wave observatories is an open question. While the
unusual mass and spin of some of the discovered objects constrain progenitor scenarios,
the observed mergers are consistent with multiple interpretations. A promising
approach to solve this question is to consider the observed distributions of binary
properties and compare them to expectations from different origin scenarios. Here
we describe a new hierarchical population analysis framework to assess the relative
contribution of different formation channels simultaneously. For this study we
considered binary formation in active galactic nucleus (AGN) disks along with
phenomenological models, but the same framework can be extended to other models.
We find that high-mass and high-mass-ratio binaries appear more likely to have
an AGN origin compared to having the same origin as lower-mass events. Future
observations of high-mass black hole mergers could further disentangle the AGN
component from other channels.

text: Extreme mass-ratio inspirals (EMRIs) take place when a stellar-mass black
hole (BH) merges with a supermassive BH (SMBH). The gravitational-wave emission
from such an event is expected to be detectable by the future Laser Interferometer
Space Antenna (LISA) and other millihertz detectors. It was recently suggested
that the EMRI rate in SMBH binary systems is orders of magnitude higher than the
EMRI rate around a single SMBH with the same total mass. Here we show that this
high rate can produce thousands of SMBH–BH sources at a redshift of unity. We
predict that LISA may detect a few hundred of these EMRIs with signal-to-noise
ratio above S/N ≥8 within a 4 yr mission lifetime. The remaining subthreshold
sources will contribute to a large confusion noise, which is approximately an
order of magnitude above LISA’s sensitivity level. Finally, we suggest that the
individually detectable systems, as well as the background noise from the subthreshold
EMRIs, can be used to constrain the SMBH binary fraction in the low-redshift Universe.

text: 'The upcoming Laser Interferometer Space Antenna (LISA) is expected to detect
gravitational waves (GWs) from massive black hole binaries (MBHB). Finding the
electromagnetic (EM) counterparts for these GW events will be crucial for understanding
how and where MBHBs merge, measuring their redshifts, constraining the Hubble
constant and the graviton mass, and for other novel science applications. However,
due to poor GW sky localization, multiwavelength, time-dependent EM models are
needed to identify the right host galaxy. We studied merging MBHBs embedded in
a circumbinary disc (CBD) using high-resolution two-dimensional simulations, with
a Γ-law equation of state, incorporating viscous heating, shock heating, and radiative
cooling. We simulate the binary from large separation until after merger, allowing
us to model the decoupling of the binary from the CBD. We compute the EM signatures
and identify distinct features before, during, and after the merger. Our main
result is a multiband EM signature: we find that the MBHB produces strong thermal
X-ray emission until 1–2 d prior to the merger. However, as the binary decouples
from the CBD, the X-ray-bright minidiscs rapidly shrink in size, become disrupted,
and the accretion rate drops precipitously. As a result, the thermal X-ray luminosity
drops by orders of magnitude, and the source remains X-ray dark for several days,
regardless of any post-merger effects such as GW recoil or mass-loss. Looking
for the abrupt spectral change where the thermal X-ray disappears is a tell-tale
EM signature of LISA mergers that does not require extensive pre-merger monitoring.'

text: The early growth of black holes (BHs) in high-redshift galaxies is likely
feedback regulated. While radiative feedback has been extensively studied, the
role of mechanical feedback has received less scrutiny to date. Here, we use high-resolution
parsec-scale hydrodynamical simulations to study jet propagation and its effect
on 100 M⊙ BH accretion in the dense, low-metallicity gas expected in early protogalaxies.
As the jet propagates, it shocks the surrounding gas forming a jet cocoon. The
cocoon consists of a rapidly cooling cold phase at the interface with the background
gas and an overpressured subsonic phase of reverse shock-heated gas filling the
interior. We vary the background gas density and temperature, BH feedback efficiency,
and the jet model. We found that the width of the jet cocoon roughly follows a
scaling derived by assuming momentum conservation in the jet-propagation direction
and energy conservation in the lateral directions. Depending on the assumed gas
and jet properties, the cocoon either stays elongated to large radii or isotropizes
before reaching the Bondi radius, forming a nearly spherical bubble. Lower jet
velocities and higher background gas densities result in self-regulation to higher
momentum fluxes and elongated cocoons. In all cases, the outward cocoon momentum
flux balances the inward inflowing gas momentum flux near the Bondi radius, which
ultimately regulates BH accretion. The time-averaged accretion rate always remains
below the Bondi rate, and exceeds the Eddington rate only if the ambient medium
is dense and cold, and/or the jet is weak (low velocity and mass loading).

text: The origin of the recently discovered new class of transients, X-ray quasi-periodic
eruptions (QPEs), remains a puzzle. Due to their periodicity and association with
active galactic nuclei (AGNs), it is natural to relate these eruptions to stars
or compact objects in tight orbits around supermassive black holes (SMBHs). In
this paper, we predict the properties of emission from bow shocks produced by
stars crossing AGN discs, and compare them to the observed properties of QPEs.
We find that when a star’s orbit is retrograde and has a low inclination (≲40°)
with respect to the AGN disc and the star is massive (≳10 M⊙), the breakout emission
from the bow shock can explain the observed duration (∼hours) and X-ray luminosity
(∼few × 1042 erg s−1) of QPEs. This model can further explain various observed
features of QPEs, such as their complex luminosity evolution, the gradual decline
of luminosity of the flares over several years, the evolution of the hardness
ratio, the modulation of the luminosity during quiescent phases, and the preference
of the central SMBHs to have low masses.

text: In this paper, we study how gaseous dynamical friction (DF) affects the motion
of fly-by stellar-mass black holes (sBHs) embedded in active galactic nucleus
(AGN) discs. We perform three-body integrations of the interaction of two co-planar
sBHs in nearby, initially circular orbits around the supermassive black hole.
We find that DF can facilitate the formation of gravitationally bound near-Keplerian
binaries in AGN discs, and we delineate the discrete ranges of impact parameters
and AGN disc parameters for which such captures occur. We also report trends in
the bound binaries’ eccentricity and sense of rotation (prograde or retrograde
with respect to the background AGN disc) as a function of the impact parameter
of the initial encounter. While based on an approximate description of gaseous
friction, our results suggest that binary formation in AGN discs should be common
and may produce both prograde and retrograde, as well as both circular and eccentric
binaries.

text: The shrinking of a binary orbit driven by the interaction with a gaseous circumbinary
disc, initially advocated as a potential way to catalyse the binary merger, has
recently been debated in the case of geometrically thick (i.e. with H/R ≳ 0.1)
discs. However, a clear consensus is still missing mainly owing to numerical limitations,
such as fixed orbit binaries or lack of resolution inside the cavity carved by
the binary in its circumbinary disc. In this work, we assess the importance of
evolving the binary orbit by means of hydrodynamic simulations performed with
the code gizmo in meshless finite mass mode. In order to model the interaction
between equal mass circular binaries and their locally isothermal circumbinary
discs, we enforce hyper-Lagrangian resolution inside the cavity. We find that
fixing the binary orbit ultimately leads to an overestimate of the gravitational
torque that the gas exerts on the binary and an underestimate of the torque due
to the accretion of material on to the binary components. Furthermore, we find
that the modulation of the accretion rate on the binary orbital period is strongly
suppressed in the fixed orbit simulation, while it is clearly present in the live
binary simulations. This has potential implications for the prediction of the
observable periodicities in massive black hole binary candidates.

text: Studies of rest-frame optical emission in quasars at z>6 have historically
been limited by the wavelengths accessible by ground-based telescopes. The James
Webb Space Telescope (JWST) now offers the opportunity to probe this emission
deep into the reionization epoch. We report the observations of eight quasars
at z>6.5 using the JWST/NIRCam Wide Field Slitless Spectroscopy, as a part of
the ''A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE)"
program. Our JWST spectra cover the quasars' emission between rest frame ∼ 4100
and 5100 Å. The profiles of these quasars' broad Hβ emission lines span a FWHM
from 3000 to 6000 km s−1. The Hβ-based virial black hole (BH) masses, ranging
from 0.6 to 2.1 billion solar masses, are generally consistent with their MgII-based
BH masses. The new measurements based on the more reliable Hβ tracer thus confirm
the existence of billion solar-mass BHs in the reionization epoch. In the observed
[OIII] λλ4960,5008 doublets of these luminous quasars, broad components are more
common than narrow core components (≤ 1200 km s−1), and only one quasar shows
stronger narrow components than broad. Two quasars exhibit significantly broad
and blueshifted [OIII] emission, thought to trace galactic-scale outflows, with
median velocities of −610 km s−1 and −1430 km s−1 relative to the [CII] 158μm
line. All eight quasars show strong optical FeII emission, and follow the Eigenvector
1 relations defined by low-redshift quasars. The entire ASPIRE program will eventually
cover 25 quasars and provide a statistical sample for the studies of the BHs and
quasar spectral properties.

text: We present cosmological constraints from the Subaru Hyper Suprime-Cam (HSC)
first-year weak lensing shear catalogue using convolutional neural networks (CNNs)
and conventional summary statistics. We crop 19 3×3deg2 sub-fields from the first-year
area, divide the galaxies with redshift 0.3≤z≤1.5 into four equally-spaced redshift
bins, and perform tomographic analyses. We develop a pipeline to generate simulated
convergence maps from cosmological N-body simulations, where we account for effects
such as intrinsic alignments (IAs), baryons, photometric redshift errors, and
point spread function errors, to match characteristics of the real catalogue.
We train CNNs that can predict the underlying parameters from the simulated maps,
and we use them to construct likelihood functions for Bayesian analyses. In the
Λ cold dark matter model with two free cosmological parameters Ωm and σ8, we find
Ωm=0.278+0.037−0.035, S8≡(Ωm/0.3)0.5σ8=0.793+0.017−0.018, and the IA amplitude
AIA=0.20+0.55−0.58. In a model with four additional free baryonic parameters,
we find Ωm=0.268+0.040−0.036, S8=0.819+0.034−0.024, and AIA=−0.16+0.59−0.58, with
the baryonic parameters not being well-constrained. We also find that statistical
uncertainties of the parameters by the CNNs are smaller than those from the power
spectrum (5--24 percent smaller for S8 and a factor of 2.5--3.0 smaller for Ωm),
showing the effectiveness of CNNs for uncovering additional cosmological information
from the HSC data. With baryons, the S8 discrepancy between HSC first-year data
and Planck 2018 is reduced from ∼2.2σ to 0.3--0.5σ.

text: The black hole (BH) binaries in active galactic nuclei (AGN) are expected
to form mainly through scattering encounters in the ambient gaseous medium. Recent
simulations, including our own, have confirmed this formation pathway is highly
efficient. We perform 3D smoothed particle hydrodynamics (SPH) simulations of
BH scattering encounters in AGN discs. Using a range of impact parameters, we
probe the necessary conditions for binary capture and how different orbital trajectories
affect the dissipative effects from the gas. We identify a single range of impact
parameters, typically of width ∼0.86−1.59 binary Hill radii depending on AGN disc
density, that reliably leads to binary formation. The periapsis of the first encounter
is the primary variable that determines the outcome of the initial scattering.
We find an associated power law between the energy dissipated and the periapsis
depth to be ΔE ∝ r−b with b = 0.42 ± 0.16, where deeper encounters dissipate more
energy. Excluding accretion physics does not significantly alter these results.
We identify the region of parameter space in initial energy versus impact parameter
where a scattering leads to binary formation. Based on our findings, we provide
a ready-to-use analytic criterion that utilizes these two pre-encounter parameters
to determine the outcome of an encounter, with a reliability rate of >90
per cent. As the criterion is based directly on our simulations, it provides a
reliable and highly physically motivated criterion for predicting binary scattering
outcomes which can be used in population studies of BH binaries and mergers around
AGN.

text: The detection of starlight from the host galaxies of quasars during the reionization
epoch (z > 6) has been elusive, even with deep Hubble Space Telescope observations1,2.
The current highest redshift quasar host detected3, at z = 4.5, required the magnifying
effect of a foreground lensing galaxy. Low-luminosity quasars4,5,6 from the Hyper
Suprime-Cam Subaru Strategic Program (HSC-SSP)7 mitigate the challenge of detecting
their underlying, previously undetected host galaxies. Here we report rest-frame
optical images and spectroscopy of two HSC-SSP quasars at z > 6 with the JWST.
Using near-infrared camera imaging at 3.6 and 1.5 μm and subtracting the light
from the unresolved quasars, we find that the host galaxies are massive (stellar
masses of 13 × and 3.4 × 1010 M☉, respectively), compact and disc-like. Near-infrared
spectroscopy at medium resolution shows stellar absorption lines in the more massive
quasar, confirming the detection of the host. Velocity-broadened gas in the vicinity
of these quasars enables measurements of their black hole masses (1.4 × 109 and
2.0 × 108 M☉, respectively). Their location in the black hole mass–stellar mass
plane is consistent with the distribution at low redshift, suggesting that the
relation between black holes and their host galaxies was already in place less
than a billion years after the Big Bang.

text: The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities
to address many key astrophysical questions in a completely novel way. The synergy
with ground-based and space-born instruments in the electromagnetic domain, by
enabling multi-messenger observations, will add further to the discovery potential
of LISA. The next decade is crucial to prepare the astrophysical community for
LISA’s first observations. This review outlines the extensive landscape of astrophysical
theory, numerical simulations, and astronomical observations that are instrumental
for modeling and interpreting the upcoming LISA datastream. To this aim, the current
knowledge in three main source classes for LISA is reviewed; ultra-compact stellar-mass
binaries, massive black hole binaries, and extreme or interme-diate mass ratio
inspirals. The relevant astrophysical processes and the established modeling techniques
are summarized. Likewise, open issues and gaps in our understanding of these sources
are highlighted, along with an indication of how LISA could help making progress
in the different areas. New research avenues that LISA itself, or its joint exploitation
with upcoming studies in the electromagnetic domain, will enable, are also illustrated.
Improvements in modeling and analysis approaches, such as the combination of numerical
simulations and modern data science techniques, are discussed. This review is
intended to be a starting point for using LISA as a new discovery tool for understanding
our Universe.

text: Some Seyfert galaxies are detected in high-energy gamma rays, but the mechanism
and site of gamma-ray emission are unknown. Also, the origins of the cosmic high-energy
neutrino and MeV gamma-ray backgrounds have been veiled in mystery since their
discoveries. We propose emission from stellar-mass BHs (sBHs) embedded in disks
of active galactic nuclei as their possible sources. These sBHs are predicted
to launch jets due to the Blandford–Znajek mechanism, which can produce intense
electromagnetic, neutrino, and cosmic-ray emissions. We investigate whether these
emissions can be the sources of cosmic high-energy particles. We find that emission
from internal shocks in the jets can explain gamma rays from nearby radio-quiet
Seyfert galaxies including NGC 1068, if the Lorentz factor of the jets (Γj) is
high. On the other hand, for moderate Γj, the emission can significantly contribute
to the background gamma-ray and neutrino intensities in the ~MeV and ≲PeV bands,
respectively. Furthermore, for moderate Γj with efficient amplification of the
magnetic field and cosmic-ray acceleration, the neutrino emission from NGC 1068
and the ultrahigh-energy cosmic rays can be explained. These results suggest that
the neutrino flux from NGC 1068 as well as the background intensities of MeV gamma
rays, neutrinos, and the ultrahigh-energy cosmic rays can be explained by a unified
model. Future MeV gamma-ray satellites will test our scenario for neutrino emission.

text: The origin of stellar-mass black hole mergers discovered through gravitational
waves is being widely debated. Mergers in the disks of active galactic nuclei
(AGNs) represent a promising source of origin, with possible observational clues
in the gravitational-wave data. Beyond gravitational waves, a unique signature
of AGN-assisted mergers is electromagnetic emission from the accreting black holes.
Here we show that jets launched by accreting black holes merging in an AGN disk
can be detected as peculiar transients by infrared, optical, and X-ray observatories.
We further show that this emission mechanism can explain the possible associations
between gravitational-wave events and the optical transient ZTF 19abanrhr and
the proposed gamma-ray counterparts GW150914-GBM and LVT151012-GBM. We demonstrate
how these associations, if genuine, can be used to reconstruct the properties
of these events’ environments. Searching for infrared and X-ray counterparts to
similar electromagnetic transients in the future, once host galaxies are localized
by optical observations, could provide a smoking-gun signature of the mergers’
AGN origin.

text: Motivated by the increasing number of detections of merging black holes by
LIGO-VIRGO-KAGRA, black hole (BH) binary mergers in the discs of active galactic
nuclei (AGNs) is investigated as a possible merger channel. In this pathway, BH
encounters in the gas disc form mutually bound BH binary systems through interaction
with the gas in the disc and subsequently inspiral through gravitational torques
induced by the local gas. To determine the feasibility of this merger pathway,
we present the first three-dimensional global hydrodynamic simulations of the
formation and evolution of a stellar-mass BH binaries AGN discs with three different
AGN disc masses and five different initial radial separations. These 15 simulations
show binary capture of prograde and retrograde binaries can be successful in a
range of disc densities including cases well below that of a standard radiatively
efficient alpha disc, identifying that the majority of these captured binaries
are then subsequently hardened by the surrounding gas. The eccentricity evolution
depends strongly on the orbital rotation where prograde binaries are governed
by gravitational torques form their circumbinary mini disc, with eccentricities
being damped, while for retrograde binaries the eccentricities are excited to
>∼ 0.9 by accretion torques. In two cases, retrograde binaries ultimately undergo
a close periapsis passage which results in a merger via gravitational waves after
only a few thousand binary orbits. Thus, the merger time-scale can be far shorter
than the AGN disc lifetime. These simulations support an efficient AGN disc merger
pathway for BHs.

text: We present the first results from the JWST ASPIRE program (A SPectroscopic
survey of biased halos In the Reionization Era). This program represents an imaging
and spectroscopic survey of 25 reionization-era quasars and their environments
by utilizing the unprecedented capabilities of NIRCam Wide Field Slitless Spectroscopy
(WFSS) mode. ASPIRE will deliver the largest (∼280 arcmin^2) galaxy redshift survey
at 3-4 μm among JWST Cycle-1 programs and provide extensive legacy values for
studying the formation of the earliest supermassive black holes (SMBHs), the assembly
of galaxies, early metal enrichment, and cosmic reionization. In this first ASPIRE
paper, we report the discovery of a filamentary structure traced by the luminous
quasar J0305-3150 and ten [OIII] emitters at z=6.6. This structure has a 3D galaxy
overdensity of δgal=12.6 over 637 cMpc3, one of the most overdense structures
known in the early universe, and could eventually evolve into a massive galaxy
cluster. Together with existing VLT/MUSE and ALMA observations of this field,
our JWST observations reveal that J0305-3150 traces a complex environment where
both UV-bright and dusty galaxies are present, and indicate that the early evolution
of galaxies around the quasar is not simultaneous. In addition, we discovered
31 [OIII] emitters in this field at other redshifts, 5.3The Astrophysical Journal Letters. 2023;951(1). doi:10.3847/2041-8213/accd6f'

text: The project MOMO (Multiwavelength Observations and Modelling of OJ 287) was
set up to test predictions of binary supermassive black hole (SMBH) scenarios
and to understand disc–jet physics of the blazar OJ 287. After a correction, the
precessing binary (PB) SMBH model predicted the next main outburst of OJ 287 in
2022 October, making the outburst well observable and the model testable. We have
densely covered this period in our ongoing multifrequency radio, optical, ultraviolet
(UV), and X-ray monitoring. The predicted outburst was not detected. Instead,
OJ 287 was at low optical–UV emission levels, declining further into November.
The predicted thermal bremsstrahlung spectrum was not observed either, at any
epoch. Further, applying scaling relations, we estimate an SMBH mass of OJ 287
of 108 M⊙. The latest in a sequence of deep low states that recur every 1–2 yr
is used to determine an upper limit on the Eddington ratio and on the accretion-disc
luminosity. This limit is at least a factor of 10 lower than required by the PB
model with its massive primary SMBH of >1010 M⊙. All these results favour
alternative binary SMBH models of OJ 287 that require neither strong orbital precession
nor a very large mass of the primary SMBH.

text: It is known that the Brauer--Manin obstruction to the Hasse principle is vacuous
for smooth Fano hypersurfaces of dimension at least 3 over any number field. Moreover,
for such varieties it follows from a general conjecture of Colliot-Thélène that
the Brauer--Manin obstruction to the Hasse principle should be the only one, so
that the Hasse principle is expected to hold. Working over the field of rational
numbers and ordering Fano hypersurfaces of fixed degree and dimension by height,
we prove that almost every such hypersurface satisfies the Hasse principle provided
that the dimension is at least 3. This proves a conjecture of Poonen and Voloch
in every case except for cubic surfaces.
