However, reaching perfect balance between being simple enough or overly simplistic is a challenging task. Frequently, game-theoretic models have an underlying assumption that players, whenever they choose to execute a specific action, do so perfectly. In fact, it is rare that action execution perfectly coincides with intentions of individuals, giving rise to behavioural mistakes. The concept of incompetence of players was suggested to address this issue in game-theoretic settings. Under the assumption of incompetence, players have non-zero probabilities of executing a different strategy from the one they chose, leading to stochastic outcomes of the interactions. In this article, we survey results related to the concept of incompetence in classic as well as evolutionary game theory and provide several new results. We also suggest future extensions of the model and argue why it is important to take into account behavioural mistakes when analysing interactions among players in both economic and biological settings."}],"volume":13,"page":"231-264","publisher":"Springer Nature","type":"journal_article","year":"2023","project":[{"name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"754411"}],"language":[{"iso":"eng"}],"doi":"10.1007/s13235-022-00425-3","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"01","article_type":"original","license":"https://creativecommons.org/licenses/by/4.0/","isi":1,"ddc":["000"],"month":"03","status":"public","author":[{"first_name":"Thomas","full_name":"Graham, Thomas","last_name":"Graham"},{"last_name":"Kleshnina","first_name":"Maria","full_name":"Kleshnina, Maria","id":"4E21749C-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Jerzy A.","full_name":"Filar, Jerzy A.","last_name":"Filar"}],"publication":"Dynamic Games and Applications","quality_controlled":"1","ec_funded":1,"scopus_import":"1","citation":{"mla":"Graham, Thomas, et al. “Where Do Mistakes Lead?

Once a satisfactory overall shape is found, a subsequent design optimization adapts the beam geometry to reduce the elastic energy of the linkage while preserving the target shape.

However, theslender nature of these beams often conflicts with the structure’s load-bearing capacity.To address this issue, multiple layers are typically stacked to enhance out-of-planestiffness and prevent stability issues. The primary challenge then lies in deploying suchmulti-layered systems globally, as it requires significant shaping forces for actuation.This paper presents an alternative design approach that involves strategically connect-ing compact-to-volumetric gridshell components using weaving principles to shape athick segmented shell. This innovative approach allows for an incremental construc-tion process based entirely on deployable modules with volumetric configurations thatlocally provide the necessary structural depth for the entire system. To demonstrate thisprinciple, we present the realization of BamX, a research pavilion constructed usingdeployable cylindrical components made from raw bamboo slats. These componentsare interconnected at carefully optimized interlocking woven nodes, resulting in abending-active structural frame that is both strong and exceptionally lightweight. Todetermine the optimal topology and geometry of the pavilion, we employ an integrativecomputational approach that leverages advanced numerical optimization techniques.Our method incorporates a physics-based simulation of the bending and twisting be-havior of the bamboo ribbons. By finding the ideal locations for ribbon crossings, weensure that all external and internal forces are in global equilibrium while minimizingthe mechanical stress experienced by each ribbon. BamX exemplifies how a symbiosisof refined weaving craft and advanced computational modeling enables fascinatingnew opportunities for rethinking deployability in architecture.","lang":"eng"}],"date_updated":"2024-08-12T09:54:02Z","extern":"1","file":[{"file_name":"2023_ArchGeometry_Suzuki.pdf","access_level":"open_access","date_updated":"2024-08-12T09:52:12Z","relation":"main_file","checksum":"bf97dbf1794277f18711adef81b2e218","content_type":"application/pdf","file_id":"17421","creator":"dernst","date_created":"2024-08-12T09:52:12Z","file_size":775573,"success":1}],"_id":"17380","title":"BamX: Rethinking Deployability in Architecture through Weaving","publication_identifier":{"isbn":["9783111160115"],"eisbn":["9783111162683"]},"date_created":"2024-08-05T06:28:57Z","fulldoi":"https://doi.org/10.1515/9783111162683-016","oa_version":"Published Version","publication_status":"published","article_processing_charge":"Yes","oa":1,"editor":[{"first_name":"Kathrin","full_name":"Dörfler, Kathrin","last_name":"Dörfler"},{"full_name":"Knippers, Jan","first_name":"Jan","last_name":"Knippers"},{"full_name":"Menges, Achim","first_name":"Achim","last_name":"Menges"},{"last_name":"Parascho","full_name":"Parascho, Stefana","first_name":"Stefana"},{"full_name":"Pottmann, Helmut","first_name":"Helmut","last_name":"Pottmann"},{"last_name":"Wortmann","first_name":"Thomas","full_name":"Wortmann, Thomas"}]},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.1145/3592399","article_type":"original","day":"01","author":[{"full_name":"Vidulis, Michele","first_name":"Michele","last_name":"Vidulis"},{"last_name":"Ren","first_name":"Yingying","id":"93d68d10-3540-11ef-a265-f748a50dba3d","full_name":"Ren, Yingying"},{"full_name":"Panetta, Julian","first_name":"Julian","last_name":"Panetta"},{"last_name":"Grinspun","full_name":"Grinspun, Eitan","first_name":"Eitan"},{"last_name":"Pauly","full_name":"Pauly, Mark","first_name":"Mark"}],"status":"public","month":"08","issue":"4","publication":"ACM Transactions on Graphics","quality_controlled":"1","scopus_import":"1","citation":{"ista":"Vidulis M, Ren Y, Panetta J, Grinspun E, Pauly M. 2023.

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.","lang":"eng"}],"article_number":"73","volume":42,"type":"journal_article","publisher":"Association for Computing Machinery","language":[{"iso":"eng"}],"year":"2023"},{"doi":"10.1115/1.4056350","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_type":"original","day":"01","issue":"4","author":[{"last_name":"Wang","first_name":"Yue","full_name":"Wang, Yue"},{"full_name":"Ren, Yingying","id":"93d68d10-3540-11ef-a265-f748a50dba3d","first_name":"Yingying","last_name":"Ren"},{"last_name":"Chen","full_name":"Chen, Tian","first_name":"Tian"}],"month":"04","status":"public","quality_controlled":"1","publication":"Journal of Applied Mechanics","scopus_import":"1","citation":{"chicago":"Wang, Yue, Yingying Ren, and Tian Chen. “From Kirigami to Hydrogels: A Tutorial on Designing Conformally Transformable Surfaces.” <i>Journal of Applied Mechanics</i>.

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."}],"language":[{"iso":"eng"}],"year":"2023","type":"journal_article","publisher":"American Society of Mechanical Engineers"},{"scopus_import":"1","citation":{"mla":"Guéneau, Armaël, et al. “Melocoton: A Program Logic for Verified Interoperability between OCaml and C.” <i>Proceedings of the ACM on Programming Languages</i>, vol. 7, no.

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.","lang":"eng"}],"year":"2023","language":[{"iso":"eng"}],"publisher":"Association for Computing Machinery","type":"journal_article"},{"quality_controlled":"1","publication":"The Astrophysical Journal Letters","main_file_link":[{"url":"https://doi.org/10.3847/2041-8213/acc103","open_access":"1"}],"issue":"1","author":[{"last_name":"Tagawa","first_name":"Hiromichi","full_name":"Tagawa, Hiromichi"},{"first_name":"Shigeo S.","full_name":"Kimura, Shigeo S.","last_name":"Kimura"},{"full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","first_name":"Zoltán","last_name":"Haiman"},{"last_name":"Perna","first_name":"Rosalba","full_name":"Perna, Rosalba"},{"full_name":"Bartos, Imre","first_name":"Imre","last_name":"Bartos"}],"status":"public","month":"03","article_type":"original","day":"21","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","doi":"10.3847/2041-8213/acc103","date_published":"2023-03-21T00:00:00Z","citation":{"ieee":"H.

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."}],"extern":"1","date_updated":"2024-09-10T10:52:04Z","intvolume":"       946"},{"scopus_import":"1","citation":{"chicago":"Gayathri, V., Daniel Wysocki, Y.

While the unusual mass and spin of some of the discovered objects constrain progenitor scenarios, the observed mergers are consistent with multiple interpretations. A promising approach to solve this question is to consider the observed distributions of binary properties and compare them to expectations from different origin scenarios. Here we describe a new hierarchical population analysis framework to assess the relative contribution of different formation channels simultaneously. 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. We find that high-mass and high-mass-ratio binaries appear more likely to have an AGN origin compared to having the same origin as lower-mass events.

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"}],"volume":526,"page":"5441-5454","date_updated":"2024-09-10T14:43:04Z","intvolume":"       526","extern":"1","title":"Disappearing thermal X-ray emission as a tell-tale signature of merging massive black hole binaries","_id":"17521","publication_identifier":{"issn":["0035-8711","1365-2966"]},"date_created":"2024-09-05T09:20:27Z","oa_version":"Published Version","fulldoi":"https://doi.org/10.1093/mnras/stad3095","publication_status":"published","article_processing_charge":"No","oa":1,"date_published":"2023-10-13T00:00:00Z","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>.","short":"L.M.

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).","lang":"eng"}],"page":"4258-4275","volume":520,"publication_identifier":{"issn":["0035-8711","1365-2966"]},"date_created":"2024-09-05T09:22:35Z","_id":"17522","title":"Self-regulation of black hole accretion via jets in early protogalaxies","article_processing_charge":"No","oa":1,"fulldoi":"https://doi.org/10.1093/mnras/stad252","oa_version":"Published Version","publication_status":"published"},{"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","doi":"10.1093/mnras/stad2616","article_type":"original","day":"05","author":[{"last_name":"Tagawa","full_name":"Tagawa, Hiromichi","first_name":"Hiromichi"},{"last_name":"Haiman","first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán"}],"status":"public","month":"09","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnras/stad2616"}],"issue":"1","publication":"Monthly Notices of the Royal Astronomical Society","quality_controlled":"1","scopus_import":"1","citation":{"ieee":"H.

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"}],"page":"69-79","volume":526,"type":"journal_article","publisher":"Oxford University Press","language":[{"iso":"eng"}],"year":"2023"},{"_id":"17539","title":"Gas dynamical friction as a binary formation mechanism in AGN discs","date_created":"2024-09-05T09:53:03Z","publication_identifier":{"issn":["0035-8711","1365-2966"]},"publication_status":"published","fulldoi":"https://doi.org/10.1093/mnras/stad1412","oa_version":"Published Version","oa":1,"article_processing_charge":"No","language":[{"iso":"eng"}],"year":"2023","type":"journal_article","publisher":"Oxford University Press","page":"1126-1139","volume":523,"abstract":[{"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.

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"}],"extern":"1","intvolume":"       523","date_updated":"2024-09-12T09:46:18Z","quality_controlled":"1","publication":"Monthly Notices of the Royal Astronomical Society","issue":"1","main_file_link":[{"url":"https://doi.org/10.1093/mnras/stad1412","open_access":"1"}],"author":[{"first_name":"Stanislav","full_name":"DeLaurentiis, Stanislav","last_name":"DeLaurentiis"},{"last_name":"Epstein-Martin","first_name":"Marguerite","full_name":"Epstein-Martin, Marguerite"},{"full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","first_name":"Zoltán","last_name":"Haiman"}],"status":"public","month":"05","article_type":"original","day":"10","doi":"10.1093/mnras/stad1412","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_published":"2023-05-10T00:00:00Z","citation":{"ama":"DeLaurentiis S, Epstein-Martin M, Haiman Z.

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"}],"extern":"1","date_updated":"2024-09-18T09:30:21Z","intvolume":"       522"},{"fulldoi":"https://doi.org/10.3847/2041-8213/acc9c8","oa_version":"Published Version","publication_status":"published","article_processing_charge":"No","oa":1,"_id":"17549","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_identifier":{"issn":["2041-8205","2041-8213"]},"date_created":"2024-09-05T10:11:02Z","abstract":[{"text":"Studies of rest-frame optical emission in quasars at z>6 have historically been limited by the wavelengths accessible by ground-based telescopes. 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.","lang":"eng"}],"article_number":"L5","volume":951,"date_updated":"2024-09-18T09:53:12Z","intvolume":"       951","extern":"1","type":"journal_article","publisher":"American Astronomical

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.

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.

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."}],"main_file_link":[{"url":"https://doi.org/10.1093/mnras/stad3641","open_access":"1"}],"issue":"4","author":[{"first_name":"Connar","full_name":"Rowan, Connar","last_name":"Rowan"},{"first_name":"Henry","full_name":"Whitehead, Henry","last_name":"Whitehead"},{"full_name":"Boekholt, Tjarda","first_name":"Tjarda","last_name":"Boekholt"},{"full_name":"Kocsis, Bence","first_name":"Bence","last_name":"Kocsis"},{"first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán","last_name":"Haiman"}],"status":"public","month":"01","quality_controlled":"1","publication":"Monthly Notices of the Royal Astronomical Society","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","doi":"10.1093/mnras/stad3641","article_type":"original","date_published":"2023-01-01T00:00:00Z","scopus_import":"1","citation":{"chicago":"Rowan, Connar, Henry Whitehead, Tjarda Boekholt, Bence Kocsis, and Zoltán Haiman. “Black Hole Binaries in AGN Accretion Discs – II.
