text: "Recent years have seen great advances towards verifying large-scale systems
code. However, these verifications are usually based on hand-written assembly
or machine-code semantics for the underlying architecture that only cover a small
part of the instruction set architecture (ISA). In contrast, other recent work
has used Sail to establish formal models for large real-world architectures, including
Armv8-A and RISC-V, that are comprehensive (complete enough to boot an operating
system or hypervisor) and authoritative (automatically derived from the Arm internal
model and validated against the Arm validation suite, and adopted as the official
formal specification by RISC-V International, respectively). But the scale and
complexity of these models makes them challenging to use as a basis for verification.\r\nIn
this paper, we propose Islaris, the first system to support verification of machine
code above these complete and authoritative real-world ISA specifications. Islaris
uses a novel combination of SMT-solver-based symbolic execution (the Isla symbolic
executor) and automated reasoning in a foundational program logic (a new separation
logic we derive using Iris in Coq). We show that this approach can handle Armv8-A
and RISC-V machine code exercising a wide range of systems features, including
installing and calling exception vectors, code parametric on a relocation address
offset (from the production pKVM hypervisor); unaligned access faults; memory-mapped
IO; and compiled C code using inline assembly and function pointers."

text: "Systems code often requires fine-grained control over memory layout and pointers,
expressed using low-level (e.g., bitwise) operations on pointer values. Since
these operations go beyond what basic pointer arithmetic in C allows, they are
performed with the help of integer-pointer casts. Prior work has explored increasingly
realistic memory object models for C that account for the desired semantics of
integer-pointer casts while also being sound w.r.t. compiler optimisations, culminating
in PNVI, the preferred memory object model in ongoing discussions within the ISO
WG14 C standards committee. However, its complexity makes it an unappealing target
for verification, and no tools currently exist to verify C programs under PNVI.\r\nIn
this paper, we introduce VIP, a new memory object model aimed at supporting C
verification. VIP sidesteps the complexities of PNVI with a simple but effective
idea: a new construct that lets programmers express the intended provenances of
integer-pointer casts explicitly. At the same time, we prove VIP compatible with
PNVI, thus enabling verification on top of VIP to benefit from PNVI’s validation
with respect to practice. In particular, we build a verification tool, RefinedC-VIP,
for verifying programs under VIP semantics. As the name suggests, RefinedC-VIP
extends the recently developed RefinedC tool, which is automated yet also produces
foundational proofs in Coq. We evaluate RefinedC-VIP on a range of systems-code
idioms, and validate VIP’s expressiveness via an implementation in the Cerberus
C semantics."

text: "Today’s compilers employ a variety of non-trivial optimizations to achieve
good performance. One key trick compilers use to justify transformations of concurrent
programs is to assume that the source program has no data races: if it does, they
cause the program to have undefined behavior (UB) and give the compiler free rein.
However, verifying correctness of optimizations that exploit this assumption is
a non-trivial problem. In particular, prior work either has not proven that such
optimizations preserve program termination (particularly non-obvious when considering
optimizations that move instructions out of loop bodies), or has treated all synchronization
operations as external functions (losing the ability to reorder instructions around
them).\r\nIn this work we present Simuliris, the first simulation technique to
establish termination preservation (under a fair scheduler) for a range of concurrent
program transformations that exploit UB in the source language. Simuliris is based
on the idea of using ownership to reason modularly about the assumptions the compiler
makes about programs with well-defined behavior. This brings the benefits of concurrent
separation logics to the space of verifying program transformations: we can combine
powerful reasoning techniques such as framing and coinduction to perform thread-local
proofs of non-trivial concurrent program optimizations. Simuliris is built on
a (non-step-indexed) variant of the Coq-based Iris framework, and is thus not
tied to a particular language. In addition to demonstrating the effectiveness
of Simuliris on standard compiler optimizations involving data race UB, we also
instantiate it with Jung et al.’s Stacked Borrows semantics for Rust and generalize
their proofs of interesting type-based aliasing optimizations to account for concurrency."

text: The self-lensing of a massive black hole binary (MBHB), which occurs when
the two BHs are aligned close to the line of sight, is expected to produce periodic,
short-duration flares. Here we study the shapes of self-lensing flares (SLFs)
via general-relativistic ray tracing in a superimposed binary BH metric, in which
the emission is generated by geometrically thin accretion flows around each component.
The suite of models covers eccentric binary orbits, black hole spins, unequal
mass binaries, and different emission model geometries. We explore the above parameter
space and report how the light curves change as a function of, e.g., binary separation,
inclination, and eccentricity. We also compare our light curves to those in the
microlensing approximation, and show how strong deflections, as well as time-delay
effects, change the size and shape of the SLF. If gravitational waves (GWs) from
the inspiraling MBHB are observed by LISA, SLFs can help securely identify the
source and localizing it on the sky, and to constrain the graviton mass by comparing
the phasing of the SLFs and the GWs. Additionally, when these systems are viewed
edge-on the SLF shows a distinct dip that can be directly correlated with the
BH shadow size. This opens a new way to measure BH shadow sizes in systems that
are unresolvable by current VLBI facilities.

text: There is some weak evidence that the black hole merger named GW190521 had
a non-zero eccentricity. In addition, the component black holes' masses exceeded
the limit predicted by stellar evolution. The large masses can be explained by
successive mergers, which may be efficient in gas disks surrounding active galactic
nuclei (AGN), but it is difficult to maintain an eccentric orbit all the way to
the merger, as basic physics would argue for circularization. Here we show that
AGN-disk environments can lead to an excess of eccentric mergers, if the interactions
between single and binary black holes are frequent, and occur with mutual inclinations
of less than a few degrees. We further illustrate that this eccentric population
has a different distribution of the inclination between the spin vectors of the
black holes and their orbital angular momentum at merger, referred to as the spin-orbit
tilt, compared to the remaining circular mergers.

text: Supermassive black hole (BH) binaries are thought to produce self-lensing
flares (SLFs) when the two BHs are aligned with the line of sight. If the binary
orbit is observed nearly edge-on, we find a distinct feature in the light curve
imprinted by the relativistic shadow around the background (“source”) BH. We study
this feature by ray tracing in a binary model and predict that 1% of the current
binary candidates could show this feature. Our BH tomography method proposed here
could make it possible to extract BH shadows that are spatially unresolvable by
high-resolution very long base line interferometry (VLBI).

text: 'Linear analysis of gas flows around orbiting binaries suggests that a centrifugal
barrier ought to clear a low-density cavity around the binary and inhibit mass
transfer onto it. Modern hydrodynamics simulations have confirmed the low-density
cavity, but show that any mass flowing from large scales into the circumbinary
disk is eventually transferred onto the binary components. Even though many numerical
studies confirm this picture, it is still not understood precisely how gas parcels
overcome the centrifugal barrier and ultimately accrete. We present a detailed
analysis of the binary accretion process, using an accurate prescription for evolving
grid-based hydrodynamics with Lagrangian tracer particles that track the trajectories
of individual gas parcels. We find that binary accretion can be described in four
phases: (1) gas is viscously transported through the circumbinary disk up to the
centrifugal barrier at the cavity wall, (2) the cavity wall is tidally distorted
into accretion streams consisting of near-ballistic gas parcels on eccentric orbits,
(3) the portion of each stream moving inwards of an ``accretion horizon'''' radius
r¯≃a -- the radius beyond which no material is returned to the cavity wall --
becomes bound to a minidisk orbiting an individual binary component, and (4) the
minidisk gas accretes onto the binary component through the combined effect of
viscous and tidal stresses.'

text: Observations of the most luminous quasars at high redshifts (z>6) have revealed
that the largest supermassive black holes (SMBHs) at those epochs tend to be substantially
overmassive relative to their host galaxies compared to the local relations, suggesting
they experienced rapid early growth phases. We propose an assembly model for the
SMBHs that end up in rare massive ∼1012 M⊙ host halos at z∼6−7, applying a kinetic
feedback prescription for BHs accreting above the Eddington rate, provided by
radiation hydrodynamic simulations for the long-term evolution of the accretion-flow
structure. The large inflow rates into these halos during their assembly enable
the formation of >109 M⊙ SMBHs by z∼6, even starting from stellar-mass seeds at
z∼30, and even in the presence of outflows that reduce the BH feeding rate, especially
at early times. This mechanism also naturally yields a high BH-to-galaxy mass
ratio of >0.01 before the SMBH mass reaches MBH>109 M⊙ by z∼6. These fast-growing
SMBH progenitors are bright enough to be detected by upcoming observations with
the James Webb Space Telescope over a wide range of redshift (7The Astrophysical Journal. 2022;935(2). doi:10.3847/1538-4357/ac7daa'

text: Active galactic nuclei (AGNs) can funnel stars and stellar remnants from the
vicinity of the galactic center into the inner plane of the AGN disk. Stars reaching
this inner region can be tidally disrupted by the stellar-mass black holes in
the disk. Such micro tidal disruption events (micro-TDEs) could be a useful probe
of stellar interaction with the AGN disk. We find that micro-TDEs in AGNs occur
at a rate of ∼170 Gpc−3 yr−1. Their cleanest observational probe may be the electromagnetic
detection of tidal disruption in AGNs by heavy supermassive black holes (M• ≳
108 M⊙) that cannot tidally disrupt solar-type stars. The reconstructed rate of
such events from observations, nonetheless, appears to be much lower than our
estimated micro-TDE rate. We discuss two such micro-TDE candidates observed to
date (ASASSN-15lh and ZTF19aailpwl).

text: Ongoing and planned weak lensing (WL) surveys are becoming deep enough to
contain information on angular scales down to a few arcmin. To fully extract information
from these small scales, we must capture non-Gaussian features in the cosmological
WL signal while accurately accounting for baryonic effects. In this work, we account
for baryonic physics via a baryonic correction model that modifies the matter
distribution in dark matter-only N-body simulations, mimicking the effects of
galaxy formation and feedback. We implement this model in a large suite of ray-tracing
simulations, spanning a grid of cosmological models in Ωm−σ8 space. We then develop
a convolutional neural network (CNN) architecture to learn and constrain cosmological
and baryonic parameters simultaneously from the simulated WL convergence maps.
We find that in a Hyper-Suprime Cam-like survey, our CNN achieves a 1.7× tighter
constraint in Ωm−σ8 space (1σ area) than the power spectrum and 2.1× tighter than
the peak counts, showing that the CNN can efficiently extract non-Gaussian cosmological
information even while marginalizing over baryonic effects. When we combine our
CNN with the power spectrum, the baryonic effects degrade the constraint in Ωm−σ8
space by a factor of 2.4, compared to the much worse degradation by a factor of
4.7 or 3.7 from either method alone.

text: "In order to extract full cosmological information from next-generation large
and high-precision weak lensing (WL) surveys (e.g., Euclid, Roman, and LSST),
higher-order statistics that probe the small-scale, nonlinear regime of large-scale
structure (LSS) need to be utilized. WL peak counts, which trace overdensities
in the cosmic web, are one promising and simple statistic for constraining cosmological
parameters. The physical origin of WL peaks have previously been linked to dark
matter halos along the line of sight, and this peak-halo connection has been used
to develop various semianalytic halo-based models for predicting peak counts.
Here, we study the origin of WL peaks and the effectiveness of halo-based models
for WL peak counts using a suite of ray-tracing N-body simulations. We compare
WL peaks in convergence maps from the full simulations to those in maps created
from only particles associated with halos—the latter playing the role of a “perfect”
halo model. We find that, while halo-only contributions are able to replicate
peak counts qualitatively well, halos do not explain all WL peaks. Halos particularly
underpredict negative peaks, which are associated with local overdensities in
large-scale underdense regions along the line of sight. In addition, neglecting
nonhalo contributions to peaks counts leads to a significant bias on the parameters
(Ωm, \U0001D70E8) for surveys larger than ⪆100 deg2. We conclude that other elements
of the cosmic web, outside and far away from dark matter halos, need to be incorporated
into models of WL peaks in order to infer unbiased cosmological constraints."

text: Stellar-mass BHs (sBHs) are predicted to be embedded in active galactic nuclei
(AGN) disks due to gravitational drag and in-situ star formation. However, we
find that due to a high gas density in an AGN disk environment, compact objects
may rapidly grow to intermediate-mass BHs and deplete matter from the AGN disk
unless accretion is suppressed by some feedback process(es). These consequences
are inconsistent with AGN observations and the dynamics of the Galactic center.
Here we consider mechanical feedback mechanisms for the reduction of gas accretion.
Rapidly accreting sBHs launch winds and/or jets via the Blandford-Znajek mechanism,
which produce high-pressure shocks and cocoons. Such a shock and cocoon can spread
laterally in the plane of the disk, eject the outer regions of a circum-sBH disk
(CsBD) and puncture a hole in the AGN disk with horizontal size comparable to
the disk scale-height. Since the depletion timescale of the bound CsBD is much
shorter than the resupply timescale of gas to the sBH, the time-averaged accretion
rate onto sBHs is reduced by this process by a factor of ∼10--100. This feedback
mechanism can therefore help alleviate the sBH over-growth and AGN-disk depletion
problems. On the other hand, we find that cocoons of jets can unbind a large fraction
of the gas accreting in the disks of less massive SMBHs, which may help explain
the dearth of high-Eddington ratio AGNs with SMBH mass ≲105M⊙.

text: 'The existence of 109 M⊙ supermassive black holes (SMBHs) within the first
billion years of the Universe remains a puzzle in our conventional understanding
of black hole formation and growth. Several suggested formation pathways for these
SMBHs lead to a heavy seed, with an initial black hole mass of 104–106 M⊙. This
can lead to an overly massive BH galaxy (OMBG), whose nuclear black hole’s mass
is comparable to or even greater than the surrounding stellar mass: the black
hole to stellar mass ratio is Mbh/M* ≫ 10−3, well in excess of the typical values
at lower redshift. We investigate how long these newborn BHs remain outliers in
the Mbh − M* relation, by exploring the subsequent evolution of two OMBGs previously
identified in the Renaissance simulations. We find that both OMBGs have Mbh/M*
> 1 during their entire life, from their birth at z ≈ 15 until they merge
with much more massive haloes at z ≈ 8. We find that the OMBGs are spatially resolvable
from their more massive, 1011 M⊙, neighbouring haloes until their mergers are
complete at z ≈ 8. This affords a window for future observations with JWST and
sensitive X-ray telescopes to diagnose the heavy-seed scenario, by detecting similar
OMBGs and establishing their uniquely high black hole-to-stellar mass ratio.'

text: The LIGO–Virgo–KAGRA Collaboration recently detected gravitational waves (GWs)
from the merger of black hole–neutron star (BHNS) binary systems GW200105 and
GW200115. No coincident electromagnetic (EM) counterparts were detected. While
the mass ratio and BH spin in both systems were not sufficient to tidally disrupt
the NS outside the BH event horizon, other, magnetospheric mechanisms for EM emission
exist in this regime and depend sensitively on the NS magnetic field strength.
Combining GW measurements with EM flux upper limits, we place upper limits on
the NS surface magnetic field strength above which magnetospheric emission models
would have generated an observable EM counterpart. We consider fireball models
powered by the black hole battery mechanism, where energy is output in gamma rays
over ≲1 s. Consistency with no detection by Fermi-GBM or INTEGRAL SPI-ACS constrains
the NS surface magnetic field to ≲1015 G. Hence, joint GW detection and EM upper
limits rule out the theoretical possibility that the NSs in GW200105 and GW200115,
and the putative NS in GW190814, retain dipolar magnetic fields ≳1015 G until
merger. They also rule out formation scenarios where strongly magnetized magnetars
quickly merge with BHs. We alternatively rule out operation of the BH-battery-powered
fireball mechanism in these systems. This is the first multimessenger constraint
on NS magnetic fields in BHNS systems and a novel approach to probe fields at
this point in NS evolution. This demonstrates the constraining power that multimessenger
analyses of BHNS mergers have on BHNS formation scenarios, NS magnetic field evolution,
and the physics of BHNS magnetospheric interactions.

text: Ultra-high angular resolution in astronomy has always been an important vehicle
for making fundamental discoveries. Recent results in direct imaging of the vicinity
of the supermassive black hole in the nucleus of the radio galaxy M87 by the millimeter
VLBI system Event Horizon Telescope and various pioneering results of the Space
VLBI mission RadioAstron provided new momentum in high angular resolution astrophysics.
In both mentioned cases, the angular resolution reached the values of about 10–20
microarcseconds (0.05–0.1 nanoradian). Further developments towards at least an
order of magnitude “sharper” values, at the level of 1 microarcsecond are dictated
by the needs of advanced astrophysical studies. The paper emphasis that these
higher values can only be achieved by placing millimeter and submillimeter wavelength
interferometric systems in space. A concept of such the system, called Terahertz
Exploration and Zooming-in for Astrophysics, has been proposed in the framework
of the ESA Call for White Papers for the Voyage 2050 long term plan in 2019. In
the current paper we present new science objectives for such the concept based
on recent results in studies of active galactic nuclei and supermassive black
holes. We also discuss several approaches for addressing technological challenges
of creating a millimeter/sub-millimeter wavelength interferometric system in space.
In particular, we consider a novel configuration of a space-borne millimeter/sub-millimeter
antenna which might resolve several bottlenecks in creating large precise mechanical
structures. The paper also presents an overview of prospective space-qualified
technologies of low-noise analogue front-end instrumentation for millimeter/sub-millimeter
telescopes. Data handling and processing instrumentation is another key technological
component of a sub-millimeter Space VLBI system. Requirements and possible implementation
options for this instrumentation are described as an extrapolation of the current
state-of-the-art Earth-based VLBI data transport and processing instrumentation.
The paper also briefly discusses approaches to the interferometric baseline state
vector determination and synchronisation and heterodyning system. The technology-oriented
sections of the paper do not aim at presenting a complete set of technological
solutions for sub-millimeter (terahertz) space-borne interferometers. Rather,
in combination with the original ESA Voyage 2050 White Paper, it sharpens the
case for the next generation microarcsecond-level imaging instruments and provides
starting points for further in-depth technology trade-off studies.

text: We present a study of optically selected dual Active Galactic Nuclei (AGN)
with projected separations of 3–97 kpc. Using multiwavelength (MWL) information
(optical, X-ray, mid-IR), we characterized the intrinsic nuclear properties of
this sample and compared them with those of isolated systems. Among the 124 X-ray-detected
AGN candidates, 52 appear in pairs and 72 as single X-ray sources. Through MWL
analysis, we confirmed the presence of the AGN in >80 per cent of the detected
targets in pairs (42 out of 52). X-ray spectral analysis confirms the trend of
increasing AGN luminosity with decreasing separation, suggesting that mergers
may have contributed to triggering more luminous AGN. Through X-ray/mid-IR ratio
versus X-ray colours, we estimated a fraction of Compton-thin AGN (with 1022 cm−2
< NH < 1024 cm−2) of about 80 per cent, while about 16 per cent
are Compton-thick sources (with NH > 1024 cm−2). These fractions of obscured
sources are larger than those found in samples of isolated AGN, confirming that
pairs of AGN show higher obscuration. This trend is further confirmed by comparing
the de-reddened [O iii] emission with the observed X-ray luminosity. However,
the derived fraction of Compton-thick sources in this sample at the early stages
of merging is lower than that reported for late-merging dual-AGN samples. Comparing
NH from X-rays with that derived from E(B − V) from narrow-line regions, we found
that the absorbing material is likely to be associated with the torus or broad-line
regions. We also explored the X-ray detection efficiency of dual-AGN candidates,
finding that, when observed properly (at on-axis positions and with long exposures),
X-ray data represent a powerful way to confirm and investigate dual-AGN systems.

text: We use long-run, high-resolution hydrodynamics simulations to compute the
multi-wavelength light curves (LCs) from thermal disk emission around accreting
equal-mass supermassive black hole (BH) binaries, with a focus on revealing binary
eccentricity. LCs are obtained by modeling the disk thermodynamics with an adiabatic
equation of state, a local blackbody cooling prescription, and corrections to
approximate the effects of radiation pressure. We find that modulation of multi-band
LCs on the orbital time scale are generally in-phase (to within ∼2% of a binary
orbital period), but they contain pulse substructure in the time domain that is
not necessarily reflected in BH accretion rates M˙. We thus predict that binary-hosting
AGN will exhibit highly correlated, in-phase, periodic brightness modulations
in their low-energy disk emission. However, detectability of these modulations
in multi-wavelength observing campaigns could be seriously compromised because
observed stochastic variability in AGNs typically has a higher amplitude than
our proposed signal. It is possible that observations over temporal baselines
of many binary periods may make the signal more prominent, but this would need
to be analyzed carefully. If jet emission is predicted by M˙, then we predict
a weaker correlation with low-energy disk emission due to the differing sub-peak
structure. For the binary parameters we explore, we show that LC variability due
to hydrodynamics likely dominates Doppler brightening for all equal-mass binaries
with disk Mach numbers ≲20. A promising signature of eccentricity is weak or absent
"lump" periodicity. We find hints that a significant lag exists between M˙ and
low-energy disk emission for circular binaries, but they are in-phase for eccentric
binaries, which might explain some "orphan" blazar flares with no γ-ray counterpart.

text: Supermassive stars (SMSs) with masses of M∗≃104--105 M⊙ are invoked as possible
seeds of high-redshift supermassive black holes, but it remains under debate whether
their protostar indeed acquires sufficient mass via gas accretion overcoming radiative
feedback. We investigate protostellar growth in dynamically heated atomic-cooling
haloes (ACHs) found in recent cosmological simulations, performing three-dimensional
radiation hydrodynamical (RHD) simulations that consider stellar evolution under
variable mass accretion. We find that one of the ACHs feeds the central protostar
at rates exceeding a critical value, above which the star evolves in a cool bloating
phase and hardly produces ionizing photons. Consequently, the stellar mass reaches
M∗≳104 M⊙ unimpeded by radiative feedback. In the other ACH, where the mass supply
rate is lower, the star spends most of its life as a hot main-sequence star, emitting
intense ionizing radiation. Then, the stellar mass growth is terminated around
500 M⊙ by photoevaporation of the circumstellar disk. A series of our RHD simulations
provide a formula of the final stellar mass determined either by stellar feedback
or their lifetime as a function of the mass supply rate from the parent cloud
in the absence of stellar radiation. Combining the results with the statistical
properties of SMS-forming clouds in high-redshift quasar progenitor haloes, we
construct a top-heavy mass distribution of primordial stars over M∗≃100--105 M⊙,
approximately following a power-law spectrum of ∝M−1.3∗ with a steeper decline
at M∗≳2×104 M⊙. Their massive BH remnants would be further fed via the dense debris
disk, powering "milli-quasars" with a bolometric luminosity of Lbol ≳ 1043 erg
s−1.

text: Next-generation weak lensing (WL) surveys, such as by the Vera Rubin Observatory,
the Roman Space Telescope, and the Euclid space mission, will supply vast amounts
of data probing small, highly non-linear scales. Extracting information from these
scales requires higher-order statistics and the controlling of related systematics
such as baryonic effects. To account for baryonic effects in cosmological analyses
at reduced computational cost, semi-analytic baryonic correction models (BCMs)
have been proposed. Here, we study the accuracy of a particular BCM (the A20-BCM)
for WL peak counts, a well-studied, simple, and effective higher-order statistic.
We compare WL peak counts generated from the full hydrodynamical simulation IllustrisTNG
and a baryon-corrected version of the corresponding dark matter-only simulation
IllustrisTNG-Dark. We apply galaxy shape noise matching depths reached by DES,
KiDS, HSC, LSST, Roman, and Euclid. We find that peak counts from the A20-BCM
are (i) accurate at per cent level for peaks with S/N < 4, (ii) statistically
indistinguishable from IllustrisTNG in most current and ongoing surveys, but (iii)
insufficient for deep future surveys covering the largest solid angles, such as
LSST and Euclid. We find that the BCM matches individual peaks accurately, but
underpredicts the amplitude of the highest peaks. We conclude that the A20-BCM
is a viable substitute for full hydrodynamical simulations in cosmological parameter
estimation from beyond-Gaussian statistics for ongoing and future surveys with
modest solid angles. For the largest surveys, the A20-BCM must be refined to provide
a more accurate match, especially to the highest peaks.

text: We study the long-term evolution of the global structure of axisymmetric accretion
flows onto a black hole (BH) at rates substantially higher than the Eddington
value (M˙Edd), performing two-dimensional hydrodynamical simulations with and
without radiative diffusion. In the high-accretion optically-thick limit, where
the radiation energy is efficiently trapped within the inflow, the accretion flow
becomes adiabatic and comprises of turbulent gas in the equatorial region and
strong bipolar outflows. As a result, the mass inflow rate decreases toward the
center as M˙in∝rp with p∼0.5−0.7 and a small fraction of the inflowing gas feeds
the nuclear BH. Thus, super-Eddington accretion is sustained only when a larger
amount of gas is supplied from larger radii at >100−1000 M˙Edd. The global structure
of the flow settles down to a quasi-steady state in millions of the orbital timescale
at the BH event horizon, which is >10−100 times longer than that addressed in
previous (magneto-)RHD simulation studies. Energy transport via radiative diffusion
accelerates the outflow near the poles in the inner region but does not change
the overall properties of the accretion flow compared to the cases without diffusion.
Based on our simulation results, we provide a mechanical feedback model for super-Eddington
accreting BHs. This can be applied as a sub-grid model in large-scale cosmological
simulations that do not sufficiently resolve galactic nuclei, and to the formation
of the heaviest gravitational-wave sources via accretion in dense environments.
