text: We report an electric-field-induced giant modulation of the hole g factor
in SiGe nanocrystals. The observed effect is ascribed to a so-far overlooked contribution
to the g factor that stems from the mixing between heavy- and light-hole wave
functions. We show that the relative displacement between the confined heavy-
and light-hole states, occurring upon application of the electric field, alters
their mixing strength leading to a strong nonmonotonic modulation of the g factor.

text: We report on hole g-factor measurements in three terminal SiGe self-assembled
quantum dot devices with a top gate electrode positioned very close to the nanostructure.
Measurements of both the perpendicular as well as the parallel g-factor reveal
significant changes for a small modulation of the top gate voltage. From the observed
modulations, we estimate that, for realistic experimental conditions, hole spins
can be electrically manipulated with Rabi frequencies in the order of 100 MHz.
This work emphasises the potential of hole-based nano-devices for efficient spin
manipulation by means of the g-tensor modulation technique.

text: 'A near-equal-mass binary black hole (BH) can clear a central cavity in a
circumbinary accretion disc; however, previous works have revealed accretion streams
entering this cavity. Here we use 2D hydrodynamical simulations to study the accretion
streams and their periodic behaviour. In particular, we perform a suite of simulations,
covering different binary mass ratios q = M2/M1 in the range 0.003 ≤ q ≤ 1. In
each case, we follow the system for several thousand binary orbits, until it relaxes
to a stable accretion pattern. We find the following results: (i) the binary is
efficient in maintaining a low-density cavity. However, the time-averaged mass
accretion rate into the cavity, through narrow coherent accretion streams, is
suppressed by at most a factor of a few compared to a disc with a single BH with
the same mass; (ii) for q ≳ 0.05, the accretion rate is strongly modulated by
the binary, and depending on the precise value of q, the power spectrum of the
accretion rate shows either one, two or three distinct periods; and (iii) for
q ≲ 0.05, the accretion rate becomes steady, with no time variations. Most binaries
produced in galactic mergers are expected to have q ≳ 0.05. If the luminosity
of these binaries tracks their accretion rate, then a periodogram of their light
curve could help in their identification, and to constrain their mass ratio and
disc properties.'

text: We propose a novel use of high-redshift galaxies, discovered in deep Hubble
Space Telescope (HST) fields around strong lensing clusters. These fields probe
small comoving volumes (∼103 Mpc3) at high magnification (μ ≳ 10) and can detect
otherwise inaccessible ultra-faint galaxies. Even a few galaxies found in such
small volumes require a very high number density of collapsed dark matter (DM)
haloes. This implies significant primordial power on small scales, allowing these
observations to rule out popular alternatives to standard cold dark matter (CDM)
models, such as warm dark matter (WDM). In this work, we analytically compute
WDM halo mass functions at z = 10, including the effects of both particle free-streaming
and residual velocity dispersion. We show that the two z ≈ 10 galaxies already
detected by the Cluster Lensing And Supernova survey with Hubble (CLASH) survey
are sufficient to constrain the WDM particle mass to mx > 1 (0.9) keV at 68 per cent
(95 per cent) confidence limit (for a thermal relic relativistic at decoupling).
This limit depends only on the WDM halo mass function and, unlike previous constraints
on mx, is independent of any astrophysical modelling. The forthcoming HST Frontier
Fields can significantly tighten these constraints.

text: Pulsar timing arrays (PTAs) may eventually be able to detect not only the
stochastic gravitational-wave (GW) background of SMBH binaries, but also individual,
particularly massive binaries whose signals stick out above the background. In
this contribution, we discuss the possibility of identifying and studying such
'resolved' binaries through their electromagnetic emission. The host galaxies
of such binaries are themselves expected to be also very massive and rare, so
that out to redshifts z ≈ 0.2 a unique massive galaxy may be identified as the
host. At higher redshifts, the PTA error boxes are larger and may contain as many
as several hundred massive-galaxy interlopers. In this case, the true counterpart
may be identified, if it is accreting gas efficiently, as an active galactic nucleus
(AGN) with a peculiar spectrum and variable emission features. Specifically, the
binary's tidal torques expel the gas from the inner part of the accretion disc,
making it unusually dim in x-ray and UV bands and in broad optical emission lines.
The tails of the broad wings of any FeKα emission line may also be 'clipped' and
missing. The binary's orbital motion, as well as the gas motions it induces, may
trigger quasiperiodic variations. These include coherent flux variability, such
as luminous, multi-wavelength flares, as well as Doppler shifts of broad emission
lines and 'see-saw' oscillations in the FeKα line. Additional features, such as
evidence for a recent major merger or dual collimated jets, could also corroborate
the counterpart. These properties would make resolved PTA sources stand out among
AGN with similar overall luminosities and allow their identification.

text: Structures in Warm Dark Matter (WDM) models are exponentially suppressed below
a certain scale, characterized by the dark matter particle mass, mx. Since structures
form hierarchically, the presence of collapsed objects at high-redshifts can set
strong lower limits on mx. We place robust constraints on mx using recent results
from the {\it Swift} database of high-redshift gamma-ray bursts (GRBs). We parameterize
the redshift evolution of the ratio between the cosmic GRB rate and star formation
rate (SFR) as ∝(1+z)α, thereby allowing astrophysical uncertainties to partially
mimic the cosmological suppression of structures in WDM models. Using a maximum
likelihood estimator on two different z>4 GRB subsamples (including two bursts
at z>8), we constrain mx≳1.6-1.8 keV at 95% C.L., when marginalized over a flat
prior in α. We further estimate that 5 years of a SVOM-like mission would tighten
these constraints to mx≳2.3 keV. Our results show that GRBs are a powerful probe
of high-redshift structures, providing robust and competitive constraints on mx.

text: Observations of quasars at redshifts z > 6 reveal that 10^9 Msol supermassive
black holes (SMBHs) had already formed when the Universe was < 0.9 Gyr old. One
hypothesis for the origins of these SMBHs is that they grew from the remnants
of the first generation of massive stars, which formed in low-mass (~ 10^5 to
10^6 Msol) dark matter minihaloes at z > 20. This is the regime where baryonic
streaming motions--the relative velocities of baryons with respect to dark matter
in the early Universe--most strongly inhibit star formation by suppressing gas
infall and cooling. We investigate the impact of this effect on the growth of
the first SMBHs using a suite of high-fidelity, ellipsoidal-collapse Monte Carlo
merger-tree simulations. We find that the suppression of seed BH formation by
the streaming motions significantly reduces the number density of the most massive
BHs at z > 15, but the residual effect at lower redshifts is essentially negligible.
The streaming motions can reduce by a factor of few the number density of the
most luminous quasars at z ~ 10-11, where such objects could be detected by the
James Webb Space Telescope. We conclude, with minor theoretical caveats, that
baryonic streaming motions are unlikely to pose a significant additional obstacle
to the formation of the observed high-redshift quasar SMBHs. Nor do they appreciably
affect the heating and reionization histories of the Universe or the merger rates
of nuclear BHs in the mass and redshift ranges of interest for proposed gravitational-wave
detectors.

text: We present observations of a luminous galaxy at z = 6.573—the end of the reionization
epoch—which has been spectroscopically confirmed twice. The first spectroscopic
confirmation comes from slitless Hubble Space Telescope Advanced Camera for Surveys
grism spectra from the PEARS survey (Probing Evolution And Reionization Spectroscopically),
which show a dramatic continuum break in the spectrum at rest frame 1216 Å. The
second confirmation is done with Keck + DEIMOS. The continuum is not clearly detected
with ground-based spectra, but high wavelength resolution enables the Lyα emission
line profile to be determined. We compare the line profile to composite line profiles
at z = 4.5. The Lyα line profile shows no signature of a damping wing attenuation,
confirming that the intergalactic gas is ionized at z = 6.57. Spectra of Lyman
breaks at yet higher redshifts will be possible using comparably deep observations
with IR-sensitive grisms, even at redshifts where Lyα is too attenuated by the
neutral intergalactic medium to be detectable using traditional spectroscopy from
the ground.

text: The statistics of peak counts in reconstructed shear maps contain information
beyond the power spectrum, and can improve cosmological constraints from measurements
of the power spectrum alone if systematic errors can be controlled. We study the
effect of galaxy shape measurement errors on predicted cosmological constraints
from the statistics of shear peak counts with the Large Synoptic Survey Telescope
(LSST). We use the LSST image simulator in combination with cosmological N-body
simulations to model realistic shear maps for different cosmological models. We
include both galaxy shape noise and, for the first time, measurement errors on
galaxy shapes. We find that the measurement errors considered have relatively
little impact on the constraining power of shear peak counts for LSST.

text: Galactic nuclei are expected to be densely populated with stellar and intermediate
mass black holes. Exploring this population will have important consequences for
the observation prospects of gravitational waves as well as understanding galactic
evolution. The gas cloud G2 currently approaching Sgr A* provides an unprecedented
opportunity to probe the black hole and neutron star population of the Galactic
nucleus. We examine the possibility of a G2-black hole encounter and its detectability
with current X-ray satellites, such as Chandra and NuSTAR. We find that multiple
encounters are likely to occur close to the pericenter, which may be detectable
upon favorable circumstances. This opportunity provides an additional, important
science case for leading X-ray observatories to closely follow G2 on its way to
the nucleus.

text: 'Peaks in two-dimensional weak lensing (WL) maps contain significant cosmological
information, complementary to the WL power spectrum. This has recently been demonstrated
using N-body simulations which neglect baryonic effects. Here we employ ray-tracing
N-body simulations in which we manually steepen the density profile of each dark
matter halo, mimicking the cooling and concentration of baryons into dark matter
potential wells. We find, in agreement with previous works, that this causes a
significant increase in the amplitude of the WL power spectrum on small scales
(spherical harmonic index l>1,000). We then study the impact of the halo concentration
increase on the peak counts, and find the following. (i) Low peaks (with convergence
0.02 < kappa_peak < 0.08), remain nearly unaffected. These peaks are created by
a constellation of several halos with low masses (10^12-10^13 M_sun) and large
angular offsets from the peak center (> 0.5 R_vir); as a result, they are insensitive
to the central halo density profiles. These peaks contain most of the cosmological
information, and thus provide an unusually sensitive and unbiased probe. (ii)
The number of high peaks (with convergence kappa_peak > 0.08) is increased. However,
when the baryon effects are neglected in cosmological parameter estimation, then
the high peaks lead to a modest bias, comparable to that from the power spectrum
on relatively large-scales (l<2000), and much smaller than the bias from the power
spectrum on smaller scales (l>2,000). (iii) In the 3D parameter space (sigma_8,
Omega_m, w), the biases from the high peaks and the power spectra are in different
directions. This suggests the possibility of "self-calibration": the combination
of peak counts and power spectrum can simultaneously constrain baryonic physics
and cosmological parameters.'

text: When a sufficiently massive satellite (or secondary) black hole is embedded
in a gas disc around a (primary) supermassive black hole, it can open an empty
gap in the disc. A gap-opening secondary close to the primary will leave an imprint
in the broad component of the Fe Kα emission line, which varies in a unique and
predictable manner. If the gap persists into the innermost disc, the effect consists
of a pair of dips in the broad line which ripple blue-ward and red-ward from the
line centroid energy, respectively, as the gap moves closer to the primary. This
ripple effect could be unambiguously detectable and allow an electromagnetic monitoring
of massive black hole mergers as they occur. As the mass ratio of the secondary
to primary black hole increases to q ≳ 0.01, we expect the gap to widen, possibly
clearing a central cavity in the inner disc, which shows up in the broad Fe Kα
line component. If the secondary stalls at ≥ 102rg in its in-migration, due to
low corotating gas mass, a detectable ripple effect occurs in the broad line component
on the disc viscous time-scale as the inner disc drains and the outer disc is
dammed. If the secondary maintains an accretion disc within a central cavity,
due to dam bursting or leakage, a periodic ‘see-saw’ oscillation effect is exhibited
in the observed line profile. Here, we demonstrate the range of ripple effect
signatures potentially detectable with Astro-H and IXO/Athena, and oscillation
effects potentially detectable with XMM–Newton or LOFT for a wide variety of merger
and disc conditions, including gap width (or cavity size), disc inclination angle
and emissivity profile, damming of the accretion flow by the secondary, and a
minidisc around the satellite black hole. A systematic study of ripple effects
would require a telescope effective area substantially larger than that planned
for IXO/Athena. Future mission planning should take this into account. Observations
of the ripple effect and periodic oscillations can be used to provide an early
warning of gravitational radiation emission from the AGN. Once gravitational waves
consistent with massive black hole mergers are detected, an archival search for
the Fe Kα ripple effect or periodic oscillations will help in localizing their
origin.

text: We have performed cosmo-hydro simulations using the RAMSES code to study atomic
cooling (ACHs) haloes at z=10 with masses 5E7Msun<~M<~2E9Msun. We assume primordial
gas and H2-cooling and prior star-formation have been suppressed. We analysed
19 haloes (gas and DM) at a resolution of ~10 (proper) pc, selected from a total
volume of ~2E3 (comoving) Mpc3. This is the largest statistical hydro-sim. study
of ACHs at z>10 to date. We examine the morphology, angular momentum (AM), thermodynamic,
and turbulence of these haloes, in order to assess the prevalence of disks and
supermassive black holes (SMBHs). We find no correlation between either the magnitude
or the direction of the AM of the gas and its parent DM halo. Only 3 haloes form
rotationally supported cores. Two of the most massive haloes form massive, compact
overdense blobs. These blobs have an accretion rate ~0.5 Msun/yr (at a distance
of 100 pc), and are possible sites of SMBH formation. Our results suggest that
the degree of rotational support and the fate of the gas in a halo is determined
by its large-scale environment and merger history. In particular, the two haloes
forming blobs are located at knots of the cosmic web, cooled early on, and experienced
many mergers. The gas in these haloes is lumpy and highly turbulent, with Mach
N. >~ 5. In contrast, the haloes forming rotationally supported cores are relatively
more isolated, located midway along filaments, cooled more recently, and underwent
fewer mergers. Thus, the gas in these haloes is less lumpy and less turbulent
(Mach <~ 4), and could retain most of its AM. The remaining 14 haloes have intermediate
properties. If verified in a larger sample of haloes and with additional physics,
our results will have implications for observations of the highest-redshift galaxies
and quasars with JWST.

text: We compare the efficiency of moments and Minkowski functionals (MFs) in constraining
the subset of cosmological parameters (Omega_m,w,sigma_8) using simulated weak
lensing convergence maps. We study an analytic perturbative expansion of the MFs
in terms of the moments of the convergence field and of its spatial derivatives.
We show that this perturbation series breaks down on smoothing scales below 5',
while it shows a good degree of convergence on larger scales (15'). Most of the
cosmological distinguishing power is lost when the maps are smoothed on these
larger scales. We also show that, on scales comparable to 1', where the perturbation
series does not converge, cosmological constraints obtained from the MFs are approximately
1.5-2 times better than the ones obtained from the first few moments of the convergence
distribution --- provided that the latter include spatial information, either
from moments of gradients, or by combining multiple smoothing scales. Including
either a set of these moments or the MFs can significantly tighten constraints
on cosmological parameters, compared to the conventional method of using the power
spectrum alone.

text: The underlying basis of genetic variation in quantitative traits, in terms
of the number of causal variants and the size of their effects, is largely unknown
in natural populations. The expectation is that complex quantitative trait variation
is attributable to many, possibly interacting, causal variants, whose effects
may depend upon the sex, age and the environment in which they are expressed.
A recently developed methodology in animal breeding derives a value of relatedness
among individuals from high‐density genomic marker data, to estimate additive
genetic variance within livestock populations. Here, we adapt and test the effectiveness
of these methods to partition genetic variation for complex traits across genomic
regions within ecological study populations where individuals have varying degrees
of relatedness. We then apply this approach for the first time to a natural population
and demonstrate that genetic variation in wing length in the great tit (Parus
major) reflects contributions from multiple genomic regions. We show that a polygenic
additive mode of gene action best describes the patterns observed, and we find
no evidence of dosage compensation for the sex chromosome. Our results suggest
that most of the genomic regions that influence wing length have the same effects
in both sexes. We found a limited amount of genetic variance in males that is
attributed to regions that have no effects in females, which could facilitate
the sexual dimorphism observed for this trait. Although this exploratory work
focuses on one complex trait, the methodology is generally applicable to any trait
for any laboratory or wild population, paving the way for investigating sex‐,
age‐ and environment‐specific genetic effects and thus the underlying genetic
architecture of phenotype in biological study systems.

text: Clutch size and egg mass are life history traits that have been extensively
studied in wild bird populations, as life history theory predicts a negative trade‐off
between them, either at the phenotypic or at the genetic level. Here, we analyse
the genomic architecture of these heritable traits in a wild great tit (Parus
major) population, using three marker‐based approaches – chromosome partitioning,
quantitative trait locus (QTL) mapping and a genome‐wide association study (GWAS).
The variance explained by each great tit chromosome scales with predicted chromosome
size, no location in the genome contains genome‐wide significant QTL, and no individual
SNPs are associated with a large proportion of phenotypic variation, all of which
may suggest that variation in both traits is due to many loci of small effect,
located across the genome. There is no evidence that any regions of the genome
contribute significantly to both traits, which combined with a small, nonsignificant
negative genetic covariance between the traits, suggests the absence of genetic
constraints on the independent evolution of these traits. Our findings support
the hypothesis that variation in life history traits in natural populations is
likely to be determined by many loci of small effect spread throughout the genome,
which are subject to continued input of variation by mutation and migration, although
we cannot exclude the possibility of an additional input of major effect genes
influencing either trait.

text: Acquisition and allocation of resources are central to life‐history theory.
However, empirical work typically focuses only on allocation despite the fact
that relationships between fitness components may be governed by differences in
the ability of individuals to acquire resources across environments. Here, we
outline a statistical framework to partition the genetic basis of multivariate
plasticity into independent axes of genetic variation, and quantify for the first
time, the extent to which specific traits drive multitrait genotype–environment
interactions. Our framework generalises to analyses of plasticity, growth and
ageing. We apply this approach to a unique, large‐scale, multivariate study of
acquisition, allocation and plasticity in the life history of the cricket, Gryllus
firmus. We demonstrate that resource acquisition and allocation are genetically
correlated, and that plasticity in trade‐offs between allocation to components
of fitness is 90% dependent on genetic variance for total resource acquisition.
These results suggest that genotype–environment effects for resource acquisition
can maintain variation in life‐history components that are typically observed
in the wild.

text: In 2005, Wyart et al. [Europhys. Lett., 2005, 72, 486] showed that the low
frequency vibrational properties of jammed amorphous sphere packings can be understood
in terms of a length scale, called l*, that diverges as the system becomes marginally
unstable. Despite the tremendous success of this theory, it has been difficult
to connect the counting argument that defines l* to other length scales that diverge
near the jamming transition. We present an alternate derivation of l* based on
the onset of rigidity. This phenomenological approach reveals the physical mechanism
underlying the length scale and is relevant to a range of systems for which the
original argument breaks down. It also allows us to present the first direct numerical
measurement of l*.

text: As a function of packing fraction at zero temperature and applied stress,
an amorphous packing of spheres exhibits a jamming transition where the system
is sensitive to boundary conditions even in the thermodynamic limit. Upon further
compression, the system should become insensitive to boundary conditions provided
it is sufficiently large. Here we explore the linear response to a large class
of boundary perturbations in 2 and 3 dimensions. We consider each finite packing
with periodic-boundary conditions as the basis of an infinite square or cubic
lattice and study properties of vibrational modes at arbitrary wave vector. We
find that the stability of such modes can be understood in terms of a competition
between plane waves and the anomalous vibrational modes associated with the jamming
transition; infinitesimal boundary perturbations become irrelevant for systems
that are larger than a length scale that characterizes the transverse excitations.
This previously identified length diverges at the jamming transition.

text: Neural circuit assembly requires selection of specific cell fates, axonal
trajectories, and synaptic targets. By analyzing the function of a secreted semaphorin,
Sema-2b, in Drosophila olfactory receptor neuron (ORN) development, we identified
multiple molecular and cellular mechanisms that link these events. Notch signaling
limits Sema-2b expression to ventromedial ORN classes, within which Sema-2b cell-autonomously
sensitizes ORN axons to external semaphorins. Central-brain-derived Sema-2a and
Sema-2b attract Sema-2b-expressing axons to the ventromedial trajectory. In addition,
Sema-2b/PlexB-mediated axon-axon interactions consolidate this trajectory choice
and promote ventromedial axon-bundle formation. Selecting the correct developmental
trajectory is ultimately essential for proper target choice. These findings demonstrate
that Sema-2b couples ORN axon guidance to postsynaptic target neuron dendrite
patterning well before the final target selection phase, and exemplify how a single
guidance molecule can drive consecutive stages of neural circuit assembly with
the help of sophisticated spatial and temporal regulation.
