Elastic knots are physical realizations of closed curves embedded in 3-space. When endowed with the material thickness and bending resistance of a physical wire, these knots settle into equilibrium states that balance the forces induced by elastic deformation and self-contacts of the wire. In general, elastic knots can have many distinct equilibrium states, i.e. they are multistable mechanical systems. We propose a computational pipeline that combines randomized spatial sampling and physics simulation to efficiently find stable equilibrium states of elastic knots. Leveraging results from knot theory, we run our pipeline on thousands of different topological knot types to create an extensive data set of multistable knots. By applying a series of filters to this data, we discover new transformable knots with interesting geometric and physical properties. A further analysis across knot types reveals geometric and topological patterns, yielding constructive principles that generalize beyond the currently tabulated knot types. We show how multistable elastic knots can be used to design novel deployable structures and engaging recreational puzzles. Several physical prototypes at different scales highlight these applications and validate our simulation."}],"intvolume":"        42","_id":"17381","title":"Computational exploration of multistable elastic knots","article_number":"73","publication_status":"published"},{"day":"01","quality_controlled":"1","date_updated":"2024-08-12T09:45:05Z","extern":"1","publication":"Journal of Applied Mechanics","intvolume":"        90","oa_version":"None","abstract":[{"text":"Elastic surfaces that morph between multiple geometrical configurations are of significant engineering value, with applications ranging from the deployment of space-based photovoltaic arrays, the erection of temporary shelters, and the realization of flexible display systems, to understanding the encapsulation and release of viral RNAs. In general, ensuring that a shape with a planar rest configuration can deploy into a target three-dimensional (3D) shape is a nontrivial problem. Moreover, it is difficult to physically realize the local deformations necessary to achieve such global transformation. Here, we give a tutorial on applying conformal mapping to rationalize the geometrical deformation of several microstructure designs. A conformal map is a function that locally preserves angles and shapes but not lengths: some regions are scaled (enlarged or shrunk) more than others. To transform a planar surface to 3D, we implement uniform local scalings as mechanical deformations. Numerous natural and architected material systems exhibit such behavior, including kirigami, origami, hydrogel, linkage mechanisms, and fabric membranes. The design and fabrication of conformally transformable surfaces is a transdisciplinary challenge involving insights from advanced manufacturing, computational design, material science, and mechanics. By recognizing that many material systems exhibit isotropic deformation, we hope to inspire researchers to adopt conformal mapping in designing next-generation surface-based engineering systems.","lang":"eng"}],"_id":"17382","title":"From kirigami to hydrogels: A tutorial on designing conformally transformable surfaces","publication_status":"published","article_number":"JAM-22-1358","doi":"10.1115/1.4056350","article_type":"original","type":"journal_article","publication_identifier":{"eissn":["1528-9036"],"issn":["0021-8936"]},"publisher":"American Society of Mechanical Engineers","issue":"4","volume":90,"year":"2023","scopus_import":"1","month":"04","author":[{"full_name":"Wang, Yue","last_name":"Wang","first_name":"Yue"},{"full_name":"Ren, Yingying","last_name":"Ren","id":"93d68d10-3540-11ef-a265-f748a50dba3d","first_name":"Yingying"},{"full_name":"Chen, Tian","last_name":"Chen","first_name":"Tian"}],"language":[{"iso":"eng"}],"status":"public","article_processing_charge":"No","citation":{"short":"Y.

In this paper, we take the first steps towards the goal of developing program logics for multi-language verification. Specifically, we present Melocoton, a multi-language program verification system for reasoning about OCaml, C, and their interactions through the OCaml FFI. Melocoton consists of the first formal semantics of (a large subset of) the OCaml FFI—previously only described in prose in the OCaml manual—as well as the first program logic to reason about the interactions of program components written in OCaml and C.

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.

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."}],"publication":"Proceedings of the ACM on Programming Languages","publication_identifier":{"issn":["2475-1421"]},"scopus_import":"1","month":"01","volume":7,"citation":{"ieee":"M.

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.","lang":"eng"}],"publication":"The Astrophysical Journal Letters"},{"extern":"1","date_updated":"2024-09-10T13:31:17Z","_id":"17513","article_number":"L29","oa_version":"Published Version","doi":"10.3847/2041-8213/acbfb8","publisher":"American Astronomical Society","type":"journal_article","article_type":"original","year":"2023","issue":"2","date_published":"2023-03-13T00:00:00Z","status":"public","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_created":"2024-09-05T08:52:25Z","quality_controlled":"1","day":"13","main_file_link":[{"open_access":"1","url":"https://doi.org/10.3847/2041-8213/acbfb8"}],"publication_status":"published","title":"Gravitational wave source populations: Disentangling an AGN component","intvolume":"       945","abstract":[{"lang":"eng","text":"The astrophysical origin of over 90 compact binary mergers discovered by the LIGO and Virgo gravitational wave observatories is an open question.

The remaining subthreshold sources will contribute to a large confusion noise, which is approximately an order of magnitude above LISA’s sensitivity level.

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"}],"intvolume":"       526","title":"Disappearing thermal X-ray emission as a tell-tale signature of merging massive black hole binaries","publication_status":"published","day":"13","quality_controlled":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnras/stad3095"}],"author":[{"full_name":"Krauth, Luke Major","first_name":"Luke Major","last_name":"Krauth"},{"full_name":"Davelaar, Jordy","first_name":"Jordy","last_name":"Davelaar"},{"last_name":"Westernacher-Schneider","first_name":"John Ryan","full_name":"Westernacher-Schneider, John Ryan"},{"last_name":"Haiman","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","first_name":"Zoltán","full_name":"Haiman, Zoltán"},{"full_name":"Zrake, Jonathan","first_name":"Jonathan","last_name":"Zrake"},{"last_name":"MacFadyen","first_name":"Andrew","full_name":"MacFadyen, Andrew"}],"language":[{"iso":"eng"}],"page":"5441-5454","citation":{"mla":"Krauth, Luke Major, et al. “Disappearing Thermal X-Ray Emission as a Tell-Tale Signature of Merging Massive Black Hole Binaries.” <i>Monthly Notices of the Royal Astronomical Society</i>, vol. 526, no. 4, Oxford University Press, 2023, pp. 5441–54, doi:<a href=\"https://doi.org/10.1093/mnras/stad3095\">10.1093/mnras/stad3095</a>.","ieee":"L.

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)."}],"intvolume":"       520","title":"Self-regulation of black hole accretion via jets in early protogalaxies","publication_status":"published","main_file_link":[{"url":"https://doi.org/10.1093/mnras/stad252","open_access":"1"}],"day":"27","quality_controlled":"1"},{"extern":"1","date_updated":"2024-09-11T08:52:17Z","doi":"10.1093/mnras/stad2616","oa_version":"Published Version","_id":"17527","issue":"1","year":"2023","publisher":"Oxford University Press","type":"journal_article","article_type":"original","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_created":"2024-09-05T09:30:18Z","date_published":"2023-09-05T00:00:00Z","status":"public","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnras/stad2616"}],"day":"05","quality_controlled":"1","abstract":[{"text":"The origin of the recently discovered new class of transients, X-ray quasi-periodic eruptions (QPEs), remains a puzzle.

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.","lang":"eng"}],"intvolume":"       526","publication":"Monthly Notices of the Royal Astronomical Society","publication_status":"published","title":"Flares from stars crossing active galactic nucleus discs on low-inclination orbits","month":"09","scopus_import":"1","volume":526,"publication_identifier":{"issn":["0035-8711","1365-2966"]},"oa":1,"language":[{"iso":"eng"}],"author":[{"full_name":"Tagawa, Hiromichi","first_name":"Hiromichi","last_name":"Tagawa"},{"last_name":"Haiman","first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán"}],"article_processing_charge":"No","citation":{"ieee":"H.

We perform three-body integrations of the interaction of two co-planar sBHs in nearby, initially circular orbits around the supermassive black hole. We find that DF can facilitate the formation of gravitationally bound near-Keplerian binaries in AGN discs, and we delineate the discrete ranges of impact parameters and AGN disc parameters for which such captures occur. We also report trends in the bound binaries’ eccentricity and sense of rotation (prograde or retrograde with respect to the background AGN disc) as a function of the impact parameter of the initial encounter. While based on an approximate description of gaseous friction, our results suggest that binary formation in AGN discs should be common and may produce both prograde and retrograde, as well as both circular and eccentric binaries.","lang":"eng"}],"intvolume":"       523","title":"Gas dynamical friction as a binary formation mechanism in AGN discs","publication_status":"published"},{"publication_status":"published","title":"The importance of live binary evolution in numerical simulations of binaries embedded in circumbinary discs","publication":"Monthly Notices of the Royal Astronomical Society","abstract":[{"text":"The shrinking of a binary orbit driven by the interaction with a gaseous circumbinary disc, initially advocated as a potential way to catalyse the binary merger, has recently been debated in the case of geometrically thick (i.e. with H/R ≳ 0.1) discs. However, a clear consensus is still missing mainly owing to numerical limitations, such as fixed orbit binaries or lack of resolution inside the cavity carved by the binary in its circumbinary disc. In this work, we assess the importance of evolving the binary orbit by means of hydrodynamic simulations performed with the code gizmo in meshless finite mass mode. In order to model the interaction between equal mass circular binaries and their locally isothermal circumbinary discs, we enforce hyper-Lagrangian resolution inside the cavity. We find that fixing the binary orbit ultimately leads to an overestimate of the gravitational torque that the gas exerts on the binary and an underestimate of the torque due to the accretion of material on to the binary components. Furthermore, we find that the modulation of the accretion rate on the binary orbital period is strongly suppressed in the fixed orbit simulation, while it is clearly present in the live binary simulations. This has potential implications for the prediction of the observable periodicities in massive black hole binary candidates.","lang":"eng"}],"intvolume":"       522","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnras/stad1070"}],"quality_controlled":"1","day":"12","oa":1,"page":"1569-1574","citation":{"short":"A.

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.

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 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."}]},{"year":"2023","issue":"4","article_type":"original","type":"journal_article","publisher":"Oxford University Press (OUP)","date_created":"2024-09-05T10:32:08Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","status":"public","date_published":"2023-01-01T00:00:00Z","date_updated":"2024-09-18T12:11:28Z","extern":"1","doi":"10.1093/mnras/stad3641","_id":"17557","oa_version":"Published Version","volume":527,"month":"01","scopus_import":"1","publication_identifier":{"issn":["0035-8711","1365-2966"]},"oa":1,"page":"10448-10468","article_processing_charge":"No","citation":{"ama":"Rowan C, Whitehead H, Boekholt T, Kocsis B, Haiman Z.

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"}]},{"title":"Detection of stellar light from quasar host galaxies at redshifts above 6","publication_status":"published","publication":"Nature","abstract":[{"lang":"eng","text":"The detection of starlight from the host galaxies of quasars during the reionization epoch (z > 6) has been elusive, even with deep Hubble Space Telescope observations1,2. The current highest redshift quasar host detected3, at z = 4.5, required the magnifying effect of a foreground lensing galaxy. Low-luminosity quasars4,5,6 from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP)7 mitigate the challenge of detecting their underlying, previously undetected host galaxies. Here we report rest-frame optical images and spectroscopy of two HSC-SSP quasars at z > 6 with the JWST. Using near-infrared camera imaging at 3.6 and 1.5 μm and subtracting the light from the unresolved quasars, we find that the host galaxies are massive (stellar masses of 13 × and 3.4 × 1010 M☉, respectively), compact and disc-like. Near-infrared spectroscopy at medium resolution shows stellar absorption lines in the more massive quasar, confirming the detection of the host. Velocity-broadened gas in the vicinity of these quasars enables measurements of their black hole masses (1.4 × 109 and 2.0 × 108 M☉, respectively). Their location in the black hole mass–stellar mass plane is consistent with the distribution at low redshift, suggesting that the relation between black holes and their host galaxies was already in place less than a billion years after the Big Bang."}],"intvolume":"       621","main_file_link":[{"url":" https://doi.org/10.48550/arXiv.2211.14329","open_access":"1"}],"quality_controlled":"1","day":"28","arxiv":1,"oa":1,"page":"51-55","article_processing_charge":"No","citation":{"apa":"Ding, X., Onoue, M., Silverman, J.

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.

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."}],"publication":"The Astrophysical Journal","year":"2023","issue":"1","publisher":"American Astronomical Society","article_type":"original","type":"journal_article","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_created":"2024-09-05T12:28:06Z","date_published":"2023-09-12T00:00:00Z","status":"public","extern":"1","date_updated":"2024-09-19T11:45:10Z","doi":"10.3847/1538-4357/ace71d","article_number":"23","_id":"17584","oa_version":"Published Version"},{"article_type":"original","type":"journal_article","publisher":"American Astronomical Society","year":"2023","issue":"1","status":"public","date_published":"2023-06-06T00:00:00Z","date_created":"2024-09-05T12:41:47Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_updated":"2024-09-23T12:36:58Z","extern":"1","article_number":"13","_id":"17594","oa_version":"Published Version","doi":"10.3847/1538-4357/acc4bb","publication_identifier":{"issn":["0004-637X","1538-4357"]},"volume":950,"scopus_import":"1","month":"06","citation":{"ieee":"H.

Mergers in the disks of active galactic nuclei (AGNs) represent a promising source of origin, with possible observational clues in the gravitational-wave data. Beyond gravitational waves, a unique signature of AGN-assisted mergers is electromagnetic emission from the accreting black holes. Here we show that jets launched by accreting black holes merging in an AGN disk can be detected as peculiar transients by infrared, optical, and X-ray observatories. We further show that this emission mechanism can explain the possible associations between gravitational-wave events and the optical transient ZTF 19abanrhr and the proposed gamma-ray counterparts GW150914-GBM and LVT151012-GBM. We demonstrate how these associations, if genuine, can be used to reconstruct the properties of these events’ environments. Searching for infrared and X-ray counterparts to similar electromagnetic transients in the future, once host galaxies are localized by optical observations, could provide a smoking-gun signature of the mergers’ AGN origin."}],"intvolume":"       950"}]
