text: 'Supermassive black holes (SMBHs) pair and form bound binaries after their
host galaxies merge. In a gas-rich merger, accretion discs are expected to form
around the binary and its components. These discs control the binary orbital evolution
until the system is compact enough for gravitational waves to drive the SMBHs
to coalescence. In this work, we implemented a time-dependent one-dimensional
model to follow the long-term evolution of the coupled binary+disc system, from
a separation of 10^5 down to 20 Schwarzschild radii. We run different models changing
the system parameters, including the binary mass ratio q ≤ 0.3 and a factor of
γ that controls the inflow across the gap created by the secondary. We find that
our implementation yields higher residual masses and longer binary residence times
than previous studies. Our main conclusion is the non-steady-state nature of the
evolution of the system: the properties the disc had when the binary was still
at large separations influence its whole evolution. To recover steady state, the
binary residence time would have to be much longer than the inflow time-scale
of the disc throughout their entire history, which in general is not satisfied.'

text: Black hole (BH) mergers detectable with the Laser Interferometer Gravitational-wave
Observatory (LIGO) can occur in active galactic nucleus (AGN) disks. Here we parameterize
the merger rates, the mass spectrum, and the spin spectrum of BHs in AGN disks.
The predicted merger rate spans ∼10−3–104 Gpc−1 yr−1, so upper limits from LIGO
(<212 Gpc−1 yr−1) already constrain it. The predicted mass spectrum has the form
of a broken power law, consisting of a pre-existing BH power-law mass spectrum
and a harder power-law mass spectrum resulting from mergers. The predicted spin
spectrum is multipeaked with the evolution of retrograde spin BHs in the gas disk
playing a key role. We outline the large uncertainties in each of these LIGO observables
for this channel and we discuss ways in which they can be constrained in the future.

text: The gravitational waves (GWs) from a binary black hole with masses 10^4≲ M≲
10^7M_⊙ can be detected with the Laser Interferometer Space Antenna (LISA) once
their orbital frequency exceeds 10^{-4}-10^{-5} Hz. The binary separation at this
stage is a=O(100)Rg (gravitational radius), and the orbital speed is v/c=O(0.1).
I argue that at this stage, the binary will be producing bright electromagnetic
(EM) radiation via gas bound to the individual BHs. Both BHs will have their own
photospheres in X-ray and possibly also in optical bands. Relativistic Doppler
modulations and lensing effects will inevitably imprint periodic variability in
the EM light-curve, tracking the phase of the orbital motion, and serving as a
template for the GW inspiral waveform. Advanced localization of the source by
LISA weeks to months prior to merger will enable a measurement of this EM chirp
by wide-field X-ray or optical instruments. A comparison of the phases of the
GW and EM chirp signals will help break degeneracies between system parameters,
and probe a fractional difference difference Δ v in the propagation speed of photons
and gravitons as low as Δ v/c ≈ 10^{-17}.

text: We present the results of 2D, moving-mesh, viscous hydrodynamical simulations
of an accretion disc around a merging supermassive black hole binary (SMBHB).
The simulation is pseudo-Newtonian, with the BHs modelled as point masses with
a Paczynski–Wiita potential, and includes viscous heating, shock heating, and
radiative cooling. We follow the gravitational inspiral of an equal-mass binary
with a component mass Mbh = 106 M⊙ from an initial separation of 60rg (where rg
≡ GMbh/c2 is the gravitational radius) to the merger. We find that a central,
low-density cavity forms around the binary, as in previous work, but that the
BHs capture gas from the circumbinary disc and accrete efficiently via their own
minidiscs, well after their inspiral outpaces the viscous evolution of the disc.
The system remains luminous, displaying strong periodicity at twice the binary
orbital frequency throughout the entire inspiral process, all the way to the merger.
In the soft X-ray band, the thermal emission is dominated by the inner edge of
the circumbinary disc with especially clear periodicity in the early inspiral.
By comparison, harder X-ray emission is dominated by the minidiscs, and the light
curve is initially more noisy but develops a clear periodicity in the late inspiral
stage. This variability pattern should help identify the electromagnetic counterparts
of SMBHBs detected by the space-based gravitational-wave detector LISA.

text: Observations of high-redshift quasars indicate that supermassive black holes
(SMBHs) with masses greater than ∼109 M⊙ were assembled within the first billion
years after the Big Bang. It is unclear how such massive black holes (BHs) formed
so early. One possible explanation is that these SMBHs were seeded by "heavy"
direct collapse black holes (DCBHs) with masses of MBH ≈ 105 M⊙, but observations
have not yet confirmed or refuted this scenario. In this Letter, we utilize a
cosmological N-body simulation to demonstrate that before they grow roughly an
order of magnitude in mass, DCBHs will have BH mass to halo mass ratios that are
much higher than expected for BH remnants of Population III (Pop III) stars that
have grown to the same mass (∼106 M⊙). We also show that when Tvir ≈ 104 K halos
(the potential sites of DCBH formation) merge with much larger nearby halos (Mh
> 1010 M⊙), they almost always orbit their larger host halos with a separation
of a few kpc, which is sufficient to be spatially resolved with future X-ray and
infrared telescopes. Thus, we propose that a future X-ray mission such as Lynx,
combined with infrared observations, will be able to distinguish high-redshift
DCBHs from smaller BH seeds due to the unusually high BH mass to stellar mass
ratios of the faintest observed quasars, with inferred BH masses below ∼106 M⊙.

text: Gravitational waves (GWs) in the nano-hertz band are great tools for understanding
the cosmological evolution of supermassive black holes (SMBHs) in galactic nuclei.
We consider SMBH binaries in high-z ultra-luminous infrared galaxies (ULIRGs)
as sources of a stochastic GW background (GWB). ULIRGs are likely associated with
gas-rich galaxy mergers containing SMBHs that possibly occur at most once in the
life of galaxies, unlike multiple dry mergers at low redshift. Adopting a well-established
sample of ULIRGs, we study the properties of the GWB due to coalescing binary
SMBHs in these galaxies. Since the ULIRG population peaks at z>1.5, the amplitude
of the GWB is not affected even if BH mergers are delayed by as long as ∼ 10 Gyrs.
Despite the rarity of the high-z ULIRGs, we find a tension with the upper limits
from Pulsar Timing Array (PTA) experiments. This result suggests that if a fraction
fm,gal of ULIRGs are associated with SMBH binaries, then no more than 20fm,gal(λEdd/0.3)5/3(tlife/30
Myr) % of the binary SMBHs in ULIRGs can merge within a Hubble time, for plausible
values of the Eddington ratio of ULIRGs (λEdd) and their lifetime (tlife).

text: We have developed a semi-analytic framework to model the large-scale evolution
of the first Population III (Pop III) stars and the transition to metal-enriched
star formation. Our model follows dark matter haloes from cosmological N-body
simulations, utilizing their individual merger histories and three-dimensional
positions, and applies physically motivated prescriptions for star formation and
feedback from Lyman–Werner (LW) radiation, hydrogen ionizing radiation, and external
metal enrichment due to supernovae winds. This method is intended to complement
analytic studies, which do not include clustering or individual merger histories,
and hydrodynamical cosmological simulations, which include detailed physics, but
are computationally expensive and have limited dynamic range. Utilizing this technique,
we compute the cumulative Pop III and metal-enriched star formation rate density
(SFRD) as a function of redshift at z ≥ 20. We find that varying the model parameters
leads to significant qualitative changes in the global star formation history.
The Pop III star formation efficiency and the delay time between Pop III and subsequent
metal-enriched star formation are found to have the largest impact. The effect
of clustering (i.e. including the three-dimensional positions of individual haloes)
on various feedback mechanisms is also investigated. The impact of clustering
on LW and ionization feedback is found to be relatively mild in our fiducial model,
but can be larger if external metal enrichment can promote metal-enriched star
formation over large distances.

text: Weak lensing maps contain information beyond two-point statistics on small
scales. Much recent work has tried to extract this information through a range
of different observables or via nonlinear transformations of the lensing field.
Here we train and apply a 2D convolutional neural network to simulated noiseless
lensing maps covering 96 different cosmological models over a range of {Ωm,σ8}.
Using the area of the confidence contour in the {Ωm,σ8} plane as a figure-of-merit,
derived from simulated convergence maps smoothed on a scale of 1.0 arcmin, we
show that the neural network yields ≈5× tighter constraints than the power spectrum,
and ≈4× tighter than the lensing peaks. Such gains illustrate the extent to which
weak lensing data encode cosmological information not accessible to the power
spectrum or even other, non-Gaussian statistics such as lensing peaks.

text: We study low-density axisymmetric accretion flows onto black holes (BHs) with
two-dimensional hydrodynamical simulations, adopting the α-viscosity prescription.
When the gas angular momentum is low enough to form a rotationally supported disk
within the Bondi radius (RB), we find a global steady accretion solution. The
solution consists of a rotational equilibrium distribution at r∼RB, where the
density follows ρ∝(1+RB/r)^3/2, surrounding a geometrically thick and optically
thin accretion disk at the centrifugal radius, where thermal energy generated
by viscosity is transported via strong convection. Physical properties of the
inner solution agree with those expected in convection-dominated accretion flows
(CDAF; ρ∝r^−1/2). In the inner CDAF solution, the gas inflow rate decreases towards
the center due to convection (M˙∝r), and the net accretion rate (including both
inflows and outflows) is strongly suppressed by several orders of magnitude from
the Bondi accretion rate M˙B The net accretion rate depends on the viscous strength,
following M˙/M˙B∝(α/0.01)^0.6. This solution holds for low accretion rates of
M˙B/M˙Edd<10^−3 having minimal radiation cooling, where M˙Edd is the Eddington
rate. In a hot plasma at the bottom (r<10^−3 RB), thermal conduction would dominate
the convective energy flux. Since suppression of the accretion by convection ceases,
the final BH feeding rate is found to be M˙/M˙B∼10^−3−10^−2. This rate is as low
as M˙/M˙Edd∼10^−7−10^−6 inferred for SgrA∗ and the nuclear BHs in M31 and M87,
and can explain the low luminosities in these sources, without invoking any feedback
mechanism.

text: The advent of time domain astronomy is revolutionizing our understanding of
the universe. Programs such as the Catalina Real-time Transient Survey (CRTS)
or the Palomar Transient Factory (PTF) surveyed millions of objects for several
years, allowing variability studies on large statistical samples. The inspection
of ≈250 k quasars in CRTS resulted in a catalog of 111 potentially periodic sources,
put forward as supermassive black hole binary (SMBHB) candidates. A similar investigation
on PTF data yielded 33 candidates from a sample of ≈35 k quasars. Working under
the SMBHB hypothesis, we compute the implied SMBHB merger rate and we use it to
construct the expected gravitational wave background (GWB) at nano-Hz frequencies,
probed by pulsar timing arrays (PTAs). After correcting for incompleteness and
assuming virial mass estimates, we find that the GWB implied by the CRTS sample
exceeds the current most stringent PTA upper limits by almost an order of magnitude.
After further correcting for the implicit bias in virial mass measurements, the
implied GWB drops significantly but is still in tension with the most stringent
PTA upper limits. Similar results hold for the PTF sample. Bayesian model selection
shows that the null hypothesis (whereby the candidates are false positives) is
preferred over the binary hypothesis at about 2.3σ and 3.6σ for the CRTS and PTF
samples respectively. Although not decisive, our analysis highlights the potential
of PTAs as astrophysical probes of individual SMBHB candidates and indicates that
the CRTS and PTF samples are likely contaminated by several false positives.

text: We propose the formation of massive pristine dark-matter (DM) halos with masses
of ∼10^8 M⊙, due to the dynamical effects of frequent mergers in rare regions
of the Universe with high baryonic streaming velocity relative to DM. Since the
streaming motion prevents gas collapse into DM halos and delays prior star formation
episodes, the gas remains metal-free until the halo virial temperatures ≳2×10^4
K. The minimum cooling mass of DM halos is boosted by a factor of ∼10−30 because
frequent major mergers of halos further inhibit gas collapse. We use Monte Carlo
merger trees to simulate the DM assembly history under a streaming velocity of
twice the root-mean-square value, and estimate the number density of massive DM
halos containing pristine gas as ≃10^−4 cMpc^−3. When the gas infall begins, efficient
Lyα cooling drives cold streams penetrating inside the halo and feeding a central
galactic disk. When one stream collides with the disk, strong shock forms a dense
and hot gas cloud, where the gas never forms H2 molecules due to effective collisional
dissociation. As a result, a massive gas cloud forms by gravitational instability
and collapses directly into a massive black hole (BH) with M∙∼10^5 M⊙. Almost
simultaneously, a galaxy with M⋆,tot∼10^6 M⊙ composed of Population III stars
forms in the nuclear region. If the typical stellar mass is as high as ∼100 M⊙,
the galaxy could be detected with the James Webb Space Telescope even at z≳15.
These massive seed BHs would be fed by continuous gas accretion from the host
galaxy, and grow to be bright quasars observed at z≳6.

text: Supermassive black hole binaries (SMBHBs) should be common in galactic nuclei
as a result of frequent galaxy mergers. Recently, a large sample of sub-parsec
SMBHB candidates was identified as bright periodically variable quasars in optical
surveys. If the observed periodicity corresponds to the redshifted binary orbital
period, the inferred orbital velocities are relativistic (v/c ≈ 0.1). The optical
and ultraviolet (UV) luminosities are expected to arise from gas bound to the
individual BHs, and would be modulated by the relativistic Doppler effect. The
optical and UV light curves should vary in tandem with relative amplitudes which
depend on the respective spectral slopes. We constructed a control sample of 42
quasars with aperiodic variability, to test whether this Doppler colour signature
can be distinguished from intrinsic chromatic variability. We found that the Doppler
signature can arise by chance in ∼20 per cent (∼37 per cent) of quasars in the
nUV (fUV) band. These probabilities reflect the limited quality of the control
sample and represent upper limits on how frequently quasars mimic the Doppler
brightness+colour variations. We performed separate tests on the periodic quasar
candidates, and found that for the majority, the Doppler boost hypothesis requires
an unusually steep UV spectrum or an unexpectedly large BH mass and orbital velocity.
We conclude that at most approximately one-third of these periodic candidates
can harbor Doppler-modulated SMBHBs.

text: 'The non-zero mass of neutrinos suppresses the growth of cosmic structure
on small scales. Since the level of suppression depends on the sum of the masses
of the three active neutrino species, the evolution of large-scale structure is
a promising tool to constrain the total mass of neutrinos and possibly shed light
on the mass hierarchy. In this work, we investigate these effects via a large
suite of N-body simulations that include massive neutrinos using an analytic linear-response
approximation: the Cosmological Massive Neutrino Simulations (MassiveNuS). The
simulations include the effects of radiation on the background expansion, as well
as the clustering of neutrinos in response to the nonlinear dark matter evolution.
We allow three cosmological parameters to vary: the neutrino mass sum M_nu in
the range of 0-0.6 eV, the total matter density Omega_m, and the primordial power
spectrum amplitude A_s. The rms density fluctuation in spheres of 8 comoving Mpc/h
(sigma_8) is a derived parameter as a result. Our data products include N-body
snapshots, halo catalogues, merger trees, ray- traced galaxy lensing convergence
maps for four source redshift planes between z_s=1-2.5, and ray-traced cosmic
microwave background lensing convergence maps. We describe the simulation procedures
and code validation in this paper. The data are publicly available at http://columbialensing.org.'

text: Motor output varies along the rostro-caudal axis of the tetrapod spinal cord.
At limb levels, ∼60 motor pools control the alternation of flexor and extensor
muscles about each joint, whereas at thoracic levels as few as 10 motor pools
supply muscle groups that support posture, inspiration, and expiration. Whether
such differences in motor neuron identity and muscle number are associated with
segmental distinctions in interneuron diversity has not been resolved. We show
that select combinations of nineteen transcription factors that specify lumbar
V1 inhibitory interneurons generate subpopulations enriched at limb and thoracic
levels. Specification of limb and thoracic V1 interneurons involves the Hox gene
Hoxc9 independently of motor neurons. Thus, early Hox patterning of the spinal
cord determines the identity of V1 interneurons and motor neurons. These studies
reveal a developmental program of V1 interneuron diversity, providing insight
into the organization of inhibitory interneurons associated with differential
motor output.

text: 'Male pattern baldness (MPB) is a sex-limited, age-related, complex trait.
We study MPB genetics in 205,327 European males from the UK Biobank. Here we show
that MPB is strongly heritable and polygenic, with pedigree-heritability of 0.62
(SE = 0.03) estimated from close relatives, and SNP-heritability of 0.39 (SE = 0.01)
from conventionally-unrelated males. We detect 624 near-independent genome-wide
loci, contributing SNP-heritability of 0.25 (SE = 0.01), of which 26 X-chromosome
loci explain 11.6%. Autosomal genetic variance is enriched for common variants
and regions of lower linkage disequilibrium. We identify plausible genetic correlations
between MPB and multiple sex-limited markers of earlier puberty, increased bone
mineral density (rg = 0.15) and pancreatic β-cell function (rg = 0.12). Correlations
with reproductive traits imply an effect on fitness, consistent with an estimated
linear selection gradient of -0.018 per MPB standard deviation. Overall, we provide
genetic insights into MPB: a phenotype of interest in its own right, with value
as a model sex-limited, complex trait.'

text: There are mean differences in complex traits among global human populations.
We hypothesize that part of the phenotypic differentiation is due to natural selection.
To address this hypothesis, we assess the differentiation in allele frequencies
of trait-associated SNPs among African, Eastern Asian, and European populations
for ten complex traits using data of large sample size (up to ~405,000). We show
that SNPs associated with height (P=2.46×10−5), waist-to-hip ratio (P=2.77×10−4),
and schizophrenia (P=3.96×10−5) are significantly more differentiated among populations
than matched “control” SNPs, suggesting that these trait-associated SNPs have
undergone natural selection. We further find that SNPs associated with height
(P=2.01×10−6) and schizophrenia (P=5.16×10−18) show significantly higher variance
in linkage disequilibrium (LD) scores across populations than control SNPs. Our
results support the hypothesis that natural selection has shaped the genetic differentiation
of complex traits, such as height and schizophrenia, among worldwide populations.

text: Health risk factors such as body mass index (BMI) and serum cholesterol are
associated with many common diseases. It often remains unclear whether the risk
factors are cause or consequence of disease, or whether the associations are the
result of confounding. We develop and apply a method (called GSMR) that performs
a multi-SNP Mendelian randomization analysis using summary-level data from genome-wide
association studies to test the causal associations of BMI, waist-to-hip ratio,
serum cholesterols, blood pressures, height, and years of schooling (EduYears)
with common diseases (sample sizes of up to 405,072). We identify a number of
causal associations including a protective effect of LDL-cholesterol against type-2
diabetes (T2D) that might explain the side effects of statins on T2D, a protective
effect of EduYears against Alzheimer’s disease, and bidirectional associations
with opposite effects (e.g., higher BMI increases the risk of T2D but the effect
of T2D on BMI is negative).

text: Preference for mates with similar phenotypes; that is, assortative mating,
is widely observed in humans1,2,3,4,5 and has evolutionary consequences6,7,8.
Under Fisher's classical theory6, assortative mating is predicted to induce a
signature in the genome at trait-associated loci that can be detected and quantified.
Here, we develop and apply a method to quantify assortative mating on a specific
trait by estimating the correlation (θ) between genetic predictors of the trait
from single nucleotide polymorphisms on odd- versus even-numbered chromosomes.
We show by theory and simulation that the effect of assortative mating can be
quantified in the presence of population stratification. We applied this approach
to 32 complex traits and diseases using single nucleotide polymorphism data from
~400,000 unrelated individuals of European ancestry. We found significant evidence
of assortative mating for height (θ = 3.2%) and educational attainment (θ = 2.7%),
both of which were consistent with theoretical predictions. Overall, our results
imply that assortative mating involves multiple traits and affects the genomic
architecture of loci that are associated with these traits, and that the consequence
of mate choice can be detected from a random sample of genomes.
