These two approaches have complementary benefits: refinement supports the use of programs as specifications, as well as transitive composition of proofs, whereas separation logic supports conditional specifications, as well as modular ownership reasoning about shared state. A number of verification frameworks employ these techniques in tandem, but in all such cases the benefits of the two techniques remain separate. For example, in frameworks that use relational separation logic to prove contextual refinement, the relational separation logic judgment does not support transitive composition of proofs, while the contextual refinement judgment does not support conditional specifications.  \r\nIn this paper, we propose Conditional Contextual Refinement (or CCR, for short), the first verification system to not only combine refinement and separation logic in a single framework but also to truly marry them together into a unified mechanism enjoying all the benefits of refinement and separation logic simultaneously. Specifically, unlike in prior work, CCR’s refinement specifications are both conditional (with separation logic pre- and post-conditions) and transitively composable. We implement CCR in Coq and evaluate its effectiveness on a range of interesting examples.","lang":"eng"}],"oa":1,"article_type":"original","_id":"17499","volume":7,"day":"11","doi":"10.1145/3571232","publication_identifier":{"issn":["2475-1421"]},"type":"journal_article","month":"01","oa_version":"Published Version","article_processing_charge":"No","page":"1121-1151","scopus_import":"1"},{"publisher":"Association for Computing Machinery","oa":1,"abstract":[{"text":"Prior work on multi-language program verification has achieved impressive results, including the compositional verification of complex compilers. But the existing approaches to this problem impose a variety of restrictions on the overall structure of multi-language programs (e.g. fixing the source language, fixing the set of involved languages, fixing the memory model, or fixing the semantics of interoperation). In this paper, we explore the problem of how to avoid such global restrictions.\r\nConcretely, we present DimSum: a new, decentralized approach to multi-language semantics and verification, which we have implemented in the Coq proof assistant. Decentralization means that we can define and reason about languages independently from each other (as independent modules communicating via events), but also combine and translate between them when necessary (via a library of combinators).\r\nWe apply DimSum to a high-level imperative language Rec (with an abstract memory model and function calls), a low-level assembly language Asm (with a concrete memory model, arbitrary jumps, and syscalls), and a mathematical specification language Spec. We evaluate DimSum on two case studies: an Asm library extending Rec with support for pointer comparison, and a coroutine library for Rec written in Asm. In both cases, we show how DimSum allows the Asm libraries to be abstracted to Rec-level specifications, despite the behavior of the Asm libraries not being syntactically expressible in Rec itself. We also verify an optimizing multi-pass compiler from Rec to Asm, showing that it is compatible with these Asm libraries.","lang":"eng"}],"date_updated":"2024-09-10T09:13:02Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1145/3571220"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_created":"2024-09-05T08:24:06Z","publication":"Proceedings of the ACM on Programming Languages","title":"DimSum: A decentralized approach to multi-language semantics and verification","publication_status":"published","status":"public","extern":"1","date_published":"2023-01-11T00:00:00Z","year":"2023","citation":{"ista":"Sammler MJ, Spies S, Song Y, D’Osualdo E, Krebbers R, Garg D, Dreyer D. 2023.

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."}],"publisher":"American Astronomical Society","issue":"1","intvolume":"       946","author":[{"last_name":"Tagawa","full_name":"Tagawa, Hiromichi","first_name":"Hiromichi"},{"full_name":"Kimura, Shigeo S.","first_name":"Shigeo S.","last_name":"Kimura"},{"full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","first_name":"Zoltán","last_name":"Haiman"},{"last_name":"Perna","full_name":"Perna, Rosalba","first_name":"Rosalba"},{"last_name":"Bartos","first_name":"Imre","full_name":"Bartos, Imre"}],"quality_controlled":"1","language":[{"iso":"eng"}],"status":"public","publication_status":"published","extern":"1","year":"2023","date_published":"2023-03-21T00:00:00Z","citation":{"ieee":"H.

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.

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.","lang":"eng"}],"publisher":"Oxford University Press","date_created":"2024-09-05T09:20:27Z","publication":"Monthly Notices of the Royal Astronomical Society","title":"Disappearing thermal X-ray emission as a tell-tale signature of merging massive black hole binaries","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnras/stad3095"}],"date_updated":"2024-09-10T14:43:04Z","quality_controlled":"1","language":[{"iso":"eng"}],"status":"public","extern":"1","publication_status":"published","date_published":"2023-10-13T00:00:00Z","year":"2023","citation":{"ista":"Krauth LM, Davelaar J, Westernacher-Schneider JR, Haiman Z, Zrake J, MacFadyen A. 2023.

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)."}],"oa":1,"publisher":"Oxford University Press","publication":"Monthly Notices of the Royal Astronomical Society","title":"Self-regulation of black hole accretion via jets in early protogalaxies","date_created":"2024-09-05T09:22:35Z","main_file_link":[{"url":"https://doi.org/10.1093/mnras/stad252","open_access":"1"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_updated":"2024-09-11T07:39:21Z"},{"article_type":"original","_id":"17527","volume":526,"doi":"10.1093/mnras/stad2616","day":"05","publication_identifier":{"issn":["0035-8711","1365-2966"]},"type":"journal_article","month":"09","oa_version":"Published Version","article_processing_charge":"No","page":"69-79","scopus_import":"1","author":[{"full_name":"Tagawa, Hiromichi","first_name":"Hiromichi","last_name":"Tagawa"},{"last_name":"Haiman","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán","first_name":"Zoltán"}],"intvolume":"       526","issue":"1","citation":{"apa":"Tagawa, H., &#38; Haiman, Z.

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."}],"oa":1},{"month":"05","type":"journal_article","oa_version":"Published Version","article_processing_charge":"No","page":"1126-1139","scopus_import":"1","article_type":"original","volume":523,"_id":"17539","day":"10","doi":"10.1093/mnras/stad1412","publication_identifier":{"issn":["0035-8711","1365-2966"]},"date_updated":"2024-09-12T09:46:18Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnras/stad1412"}],"publication":"Monthly Notices of the Royal Astronomical Society","title":"Gas dynamical friction as a binary formation mechanism in AGN discs","date_created":"2024-09-05T09:53:03Z","publisher":"Oxford University Press","abstract":[{"lang":"eng","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.

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."}],"oa":1,"publisher":"Oxford University Press","author":[{"last_name":"Franchini","full_name":"Franchini, Alessia","first_name":"Alessia"},{"last_name":"Lupi","full_name":"Lupi, Alessandro","first_name":"Alessandro"},{"first_name":"Alberto","full_name":"Sesana, Alberto","last_name":"Sesana"},{"first_name":"Zoltán","full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman"}],"intvolume":"       522","issue":"1","language":[{"iso":"eng"}],"quality_controlled":"1","citation":{"mla":"Franchini, Alessia, et al. “The Importance of Live Binary Evolution in Numerical Simulations of Binaries Embedded in Circumbinary Discs.” <i>Monthly Notices of the Royal Astronomical Society</i>, vol. 522, no. 1, Oxford University Press, 2023, pp. 1569–74, doi:<a href=\"https://doi.org/10.1093/mnras/stad1070\">10.1093/mnras/stad1070</a>.","ista":"Franchini A, Lupi A, Sesana A, Haiman Z. 2023.

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."}],"oa":1,"date_updated":"2024-09-18T09:53:12Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","main_file_link":[{"open_access":"1","url":"https://doi.org/10.3847/2041-8213/acc9c8"}],"title":"A SPectroscopic survey of biased halos in the reionization Era (ASPIRE): A first look at the rest-frame optical spectra of > 6.5 quasars using JWST","publication":"The Astrophysical Journal Letters","date_created":"2024-09-05T10:11:02Z"},{"_id":"17551","volume":521,"publication_identifier":{"issn":["0035-8711","1365-2966"]},"doi":"10.1093/mnras/stad686","day":"06","article_type":"original","article_processing_charge":"No","scopus_import":"1","page":"2050-2066","oa_version":"Published Version","type":"journal_article","month":"03","year":"2023","date_published":"2023-03-06T00:00:00Z","extern":"1","status":"public","publication_status":"published","citation":{"mla":"Lu, Tianhuan, et al. “Cosmological Constraints from HSC Survey First-Year Data Using Deep Learning.” <i>Monthly Notices of the Royal Astronomical Society</i>, vol. 521, no. 2, Oxford University Press, 2023, pp. 2050–66, doi:<a href=\"https://doi.org/10.1093/mnras/stad686\">10.1093/mnras/stad686</a>.","ama":"Lu T, Haiman Z, Li X.

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."}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnras/stad686"}],"date_updated":"2024-09-18T10:09:01Z","date_created":"2024-09-05T10:14:34Z","title":"Cosmological constraints from HSC survey first-year data using deep learning","publication":"Monthly Notices of the Royal Astronomical Society"},{"article_type":"original","doi":"10.1093/mnras/stad3641","publication_identifier":{"issn":["0035-8711","1365-2966"]},"volume":527,"_id":"17557","month":"01","type":"journal_article","oa_version":"Published Version","page":"10448-10468","scopus_import":"1","article_processing_charge":"No","author":[{"first_name":"Connar","full_name":"Rowan, Connar","last_name":"Rowan"},{"last_name":"Whitehead","first_name":"Henry","full_name":"Whitehead, Henry"},{"first_name":"Tjarda","full_name":"Boekholt, Tjarda","last_name":"Boekholt"},{"full_name":"Kocsis, Bence","first_name":"Bence","last_name":"Kocsis"},{"first_name":"Zoltán","full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman"}],"issue":"4","intvolume":"       527","language":[{"iso":"eng"}],"quality_controlled":"1","citation":{"chicago":"Rowan, Connar, Henry Whitehead, Tjarda Boekholt, Bence Kocsis, and Zoltán Haiman. “Black Hole Binaries in AGN Accretion Discs – II.

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 &amp;gt;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.","lang":"eng"}],"oa":1,"publisher":"Oxford University Press (OUP)"},{"publication_identifier":{"issn":["0028-0836","1476-4687"]},"day":"28","doi":"10.1038/s41586-023-06345-5","_id":"17558","volume":621,"article_type":"original","scopus_import":"1","page":"51-55","article_processing_charge":"No","oa_version":"Preprint","type":"journal_article","month":"06","quality_controlled":"1","language":[{"iso":"eng"}],"external_id":{"arxiv":["2211.14329"]},"date_published":"2023-06-28T00:00:00Z","year":"2023","extern":"1","publication_status":"published","status":"public","citation":{"short":"X.

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.","lang":"eng"}],"publisher":"Springer Science and Business Media LLC","date_created":"2024-09-05T11:28:21Z","title":"Detection of stellar light from quasar host galaxies at redshifts above 6","publication":"Nature","arxiv":1,"date_updated":"2024-09-18T12:19:50Z","main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.2211.14329"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345"},{"publisher":"Springer Science and Business Media LLC","abstract":[{"lang":"eng","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."}],"oa":1,"date_updated":"2024-09-19T07:31:45Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","main_file_link":[{"url":"https://doi.org/10.1007/s41114-022-00041-y","open_access":"1"}],"title":"Astrophysics with the laser interferometer space antenna","publication":"Living Reviews in Relativity","date_created":"2024-09-05T12:16:33Z","citation":{"ista":"Amaro-Seoane P et al. 2023.

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."}],"oa":1,"date_updated":"2024-09-19T11:45:10Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.3847/1538-4357/ace71d"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","title":"High-energy electromagnetic, neutrino, and cosmic-ray emission by stellar-mass black holes in disks of active galactic nuclei","publication":"The Astrophysical Journal","date_created":"2024-09-05T12:28:06Z"},{"publication":"The Astrophysical Journal","title":"Observable signature of merging stellar-mass black holes in active galactic nuclei","date_created":"2024-09-05T12:41:47Z","main_file_link":[{"url":"https://doi.org/10.3847/1538-4357/acc4bb","open_access":"1"}],"date_updated":"2024-09-23T12:36:58Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","abstract":[{"lang":"eng","text":"The origin of stellar-mass black hole mergers discovered through gravitational waves is being widely debated.

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.

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."}],"oa":1,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnras/stad1926"}],"date_updated":"2024-09-23T13:42:19Z","publication":"Monthly Notices of the Royal Astronomical Society","title":"Black hole binary formation in AGN discs: from isolation to merger","date_created":"2024-09-05T13:09:11Z","volume":524,"_id":"17602","doi":"10.1093/mnras/stad1926","day":"03","publication_identifier":{"issn":["0035-8711","1365-2966"]},"article_type":"original","article_processing_charge":"No","page":"2770-2796","scopus_import":"1","month":"07","type":"journal_article","oa_version":"Published Version"},{"quality_controlled":"1","language":[{"iso":"eng"}],"extern":"1","status":"public","publication_status":"published","year":"2023","date_published":"2023-06-29T00:00:00Z","citation":{"chicago":"Wang, Feige, Jinyi Yang, Joseph F.

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, 5.3<z<6.7, with half of them situated at z∼5.4 and z∼6.2. This indicates that star-forming galaxies, such as [OIII] emitters, are generally clustered at high redshifts. These discoveries demonstrate the unparalleled redshift survey capabilities of NIRCam WFSS and the potential of the full ASPIRE survey dataset.","lang":"eng"}],"publisher":"American Astronomical Society","date_created":"2024-09-05T13:14:46Z","publication":"The Astrophysical Journal Letters","title":"A SPectroscopic survey of biased halos in the reionization era (ASPIRE): JWST reveals a filamentary structure around a z = 6.61 Quasar","date_updated":"2024-09-23T14:08:58Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","main_file_link":[{"open_access":"1","url":"https://doi.org/10.3847/2041-8213/accd6f"}],"publication_identifier":{"issn":["2041-8205","2041-8213"]},"doi":"10.3847/2041-8213/accd6f","day":"29","volume":951,"_id":"17606","article_type":"original","article_number":"L4","scopus_import":"1","article_processing_charge":"No","oa_version":"Published Version","month":"06","type":"journal_article"},{"article_type":"original","_id":"17611","volume":522,"day":"23","doi":"10.1093/mnrasl/slad016","publication_identifier":{"issn":["1745-3925","1745-3933"]},"type":"journal_article","month":"02","oa_version":"Published Version","article_processing_charge":"No","page":"L84-L88","scopus_import":"1","author":[{"last_name":"Komossa","first_name":"S","full_name":"Komossa, S"},{"last_name":"Grupe","first_name":"D","full_name":"Grupe, D"},{"last_name":"Kraus","full_name":"Kraus, A","first_name":"A"},{"first_name":"M A","full_name":"Gurwell, M A","last_name":"Gurwell"},{"first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán","last_name":"Haiman"},{"first_name":"F K","full_name":"Liu, F K","last_name":"Liu"},{"full_name":"Tchekhovskoy, A","first_name":"A","last_name":"Tchekhovskoy"},{"first_name":"L C","full_name":"Gallo, L C","last_name":"Gallo"},{"first_name":"M","full_name":"Berton, M","last_name":"Berton"},{"full_name":"Blandford, R","first_name":"R","last_name":"Blandford"},{"full_name":"Gómez, J L","first_name":"J L","last_name":"Gómez"},{"first_name":"A G","full_name":"Gonzalez, A G","last_name":"Gonzalez"}],"intvolume":"       522","issue":"1","citation":{"ista":"Komossa S, Grupe D, Kraus A, Gurwell MA, Haiman Z, Liu FK, Tchekhovskoy A, Gallo LC, Berton M, Blandford R, Gómez JL, Gonzalez AG. 2023.

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 &amp;gt;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.","lang":"eng"}],"oa":1}]
