Here we study the shapes of self-lensing flares (SLFs) via general-relativistic ray tracing in a superimposed binary BH metric, in which the emission is generated by geometrically thin accretion flows around each component. The suite of models covers eccentric binary orbits, black hole spins, unequal mass binaries, and different emission model geometries. We explore the above parameter space and report how the light curves change as a function of, e.g., binary separation, inclination, and eccentricity. We also compare our light curves to those in the microlensing approximation, and show how strong deflections, as well as time-delay effects, change the size and shape of the SLF. If gravitational waves (GWs) from the inspiraling MBHB are observed by LISA, SLFs can help securely identify the source and localizing it on the sky, and to constrain the graviton mass by comparing the phasing of the SLFs and the GWs. Additionally, when these systems are viewed edge-on the SLF shows a distinct dip that can be directly correlated with the BH shadow size. This opens a new way to measure BH shadow sizes in systems that are unresolvable by current VLBI facilities.","lang":"eng"}],"article_number":"103010","article_type":"original","date_created":"2024-09-05T09:29:24Z","volume":105,"status":"public","publication_status":"published","day":"09","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","doi":"10.1103/physrevd.105.103010","issue":"10","oa":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1103/physrevd.105.103010"}],"extern":"1"},{"issue":"7900","oa":1,"main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.2010.09765"}],"extern":"1","status":"public","publication_status":"published","day":"09","doi":"10.1038/s41586-021-04333-1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","oa_version":"Preprint","abstract":[{"lang":"eng","text":"There is some weak evidence that the black hole merger named GW190521 had a non-zero eccentricity.

Modern hydrodynamics simulations have confirmed the low-density cavity, but show that any mass flowing from large scales into the circumbinary disk is eventually transferred onto the binary components. Even though many numerical studies confirm this picture, it is still not understood precisely how gas parcels overcome the centrifugal barrier and ultimately accrete. We present a detailed analysis of the binary accretion process, using an accurate prescription for evolving grid-based hydrodynamics with Lagrangian tracer particles that track the trajectories of individual gas parcels. We find that binary accretion can be described in four phases: (1) gas is viscously transported through the circumbinary disk up to the centrifugal barrier at the cavity wall, (2) the cavity wall is tidally distorted into accretion streams consisting of near-ballistic gas parcels on eccentric orbits, (3) the portion of each stream moving inwards of an ``accretion horizon'' radius r¯≃a -- the radius beyond which no material is returned to the cavity wall -- becomes bound to a minidisk orbiting an individual binary component, and (4) the minidisk gas accretes onto the binary component through the combined effect of viscous and tidal stresses.","lang":"eng"}],"volume":932,"date_created":"2024-09-05T10:17:13Z","article_type":"original","oa_version":"Published Version"},{"year":"2022","month":"08","citation":{"ista":"Hu H, Inayoshi K, Haiman Z, Li W, Quataert E, Kuiper R. 2022.

In this work, we account for baryonic physics via a baryonic correction model that modifies the matter distribution in dark matter-only N-body simulations, mimicking the effects of galaxy formation and feedback. We implement this model in a large suite of ray-tracing simulations, spanning a grid of cosmological models in Ωm−σ8 space. We then develop a convolutional neural network (CNN) architecture to learn and constrain cosmological and baryonic parameters simultaneously from the simulated WL convergence maps. We find that in a Hyper-Suprime Cam-like survey, our CNN achieves a 1.7× tighter constraint in Ωm−σ8 space (1σ area) than the power spectrum and 2.1× tighter than the peak counts, showing that the CNN can efficiently extract non-Gaussian cosmological information even while marginalizing over baryonic effects. When we combine our CNN with the power spectrum, the baryonic effects degrade the constraint in Ωm−σ8 space by a factor of 2.4, compared to the much worse degradation by a factor of 4.7 or 3.7 from either method alone.","lang":"eng"}],"volume":511,"date_created":"2024-09-05T12:02:56Z","article_type":"original","status":"public","publication_status":"published","day":"28","doi":"10.1093/mnras/stac161","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","issue":"1","extern":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnras/stac161"}],"oa":1,"publication":"Monthly Notices of the Royal Astronomical Society","publication_identifier":{"issn":["0035-8711","1365-2966"]},"quality_controlled":"1","article_processing_charge":"No","title":"Simultaneously constraining cosmology and baryonic physics via deep learning from weak lensing","author":[{"last_name":"Lu","first_name":"Tianhuan","full_name":"Lu, Tianhuan"},{"first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman","full_name":"Haiman, Zoltán"},{"full_name":"Zorrilla Matilla, José Manuel","last_name":"Zorrilla Matilla","first_name":"José Manuel"}],"type":"journal_article","date_published":"2022-01-28T00:00:00Z","month":"01","_id":"17562","date_updated":"2024-09-18T12:41:52Z","page":"1518-1528","citation":{"ama":"Lu T, Haiman Z, Zorrilla Matilla JM.

WL peak counts, which trace overdensities in the cosmic web, are one promising and simple statistic for constraining cosmological parameters. The physical origin of WL peaks have previously been linked to dark matter halos along the line of sight, and this peak-halo connection has been used to develop various semianalytic halo-based models for predicting peak counts. Here, we study the origin of WL peaks and the effectiveness of halo-based models for WL peak counts using a suite of ray-tracing N-body simulations. We compare WL peaks in convergence maps from the full simulations to those in maps created from only particles associated with halos—the latter playing the role of a “perfect” halo model. We find that, while halo-only contributions are able to replicate peak counts qualitatively well, halos do not explain all WL peaks. Halos particularly underpredict negative peaks, which are associated with local overdensities in large-scale underdense regions along the line of sight. In addition, neglecting nonhalo contributions to peaks counts leads to a significant bias on the parameters (Ωm, 𝜎8) for surveys larger than ⪆100 deg2. We conclude that other elements of the cosmic web, outside and far away from dark matter halos, need to be incorporated into models of WL peaks in order to infer unbiased cosmological constraints.","lang":"eng"}],"article_number":"023505","article_type":"original","date_created":"2024-09-05T12:03:46Z","volume":105,"status":"public","publication_status":"published","day":"07","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","doi":"10.1103/physrevd.105.023505","issue":"2","extern":"1","main_file_link":[{"url":"https://doi.org/10.1103/PhysRevD.105.023505","open_access":"1"}],"oa":1},{"issue":"1","oa":1,"extern":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.3847/1538-4357/ac45f8"}],"status":"public","publication_status":"published","day":"03","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","doi":"10.3847/1538-4357/ac45f8","oa_version":"Published Version","abstract":[{"lang":"eng","text":"Stellar-mass BHs (sBHs) are predicted to be embedded in active galactic nuclei (AGN) disks due to gravitational drag and in-situ star formation. However, we find that due to a high gas density in an AGN disk environment, compact objects may rapidly grow to intermediate-mass BHs and deplete matter from the AGN disk unless accretion is suppressed by some feedback process(es). These consequences are inconsistent with AGN observations and the dynamics of the Galactic center. Here we consider mechanical feedback mechanisms for the reduction of gas accretion. Rapidly accreting sBHs launch winds and/or jets via the Blandford-Znajek mechanism, which produce high-pressure shocks and cocoons. Such a shock and cocoon can spread laterally in the plane of the disk, eject the outer regions of a circum-sBH disk (CsBD) and puncture a hole in the AGN disk with horizontal size comparable to the disk scale-height. Since the depletion timescale of the bound CsBD is much shorter than the resupply timescale of gas to the sBH, the time-averaged accretion rate onto sBHs is reduced by this process by a factor of ∼10--100. This feedback mechanism can therefore help alleviate the sBH over-growth and AGN-disk depletion problems. On the other hand, we find that cocoons of jets can unbind a large fraction of the gas accreting in the disks of less massive SMBHs, which may help explain the dearth of high-Eddington ratio AGNs with SMBH mass ≲105M⊙."}],"article_number":"41","article_type":"original","date_created":"2024-09-05T12:13:22Z","volume":927,"scopus_import":"1","intvolume":" 927","year":"2022","_id":"17568","citation":{"apa":"Tagawa, H., Kimura, S.

Several suggested formation pathways for these SMBHs lead to a heavy seed, with an initial black hole mass of 104–106 M⊙. This can lead to an overly massive BH galaxy (OMBG), whose nuclear black hole’s mass is comparable to or even greater than the surrounding stellar mass: the black hole to stellar mass ratio is Mbh/M* ≫ 10−3, well in excess of the typical values at lower redshift. We investigate how long these newborn BHs remain outliers in the Mbh − M* relation, by exploring the subsequent evolution of two OMBGs previously identified in the Renaissance simulations. We find that both OMBGs have Mbh/M* > 1 during their entire life, from their birth at z ≈ 15 until they merge with much more massive haloes at z ≈ 8. We find that the OMBGs are spatially resolvable from their more massive, 1011 M⊙, neighbouring haloes until their mergers are complete at z ≈ 8. This affords a window for future observations with JWST and sensitive X-ray telescopes to diagnose the heavy-seed scenario, by detecting similar OMBGs and establishing their uniquely high black hole-to-stellar mass ratio."}],"article_type":"original","date_created":"2024-09-05T12:14:22Z","volume":519,"scopus_import":"1","intvolume":" 519","issue":"2","extern":"1","main_file_link":[{"url":"https://doi.org/10.1093/mnras/stac3715","open_access":"1"}],"oa":1,"status":"public","publication_status":"published","day":"20","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","doi":"10.1093/mnras/stac3715"},{"publication":"The Astrophysical Journal","article_processing_charge":"No","quality_controlled":"1","publication_identifier":{"issn":["0004-637X","1538-4357"]},"author":[{"last_name":"D’Orazio","first_name":"Daniel J.","full_name":"D’Orazio, Daniel J."},{"full_name":"Haiman, Zoltán","last_name":"Haiman","first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"},{"first_name":"Janna","last_name":"Levin","full_name":"Levin, Janna"},{"full_name":"Samsing, Johan","first_name":"Johan","last_name":"Samsing"},{"last_name":"Vigna-Gómez","first_name":"Alejandro","full_name":"Vigna-Gómez, Alejandro"}],"title":"Multimessenger constraints on magnetic fields in merging black hole–neutron star binaries","date_published":"2022-01-01T00:00:00Z","type":"journal_article","language":[{"iso":"eng"}],"publisher":"American Astronomical Society","citation":{"chicago":"D’Orazio, Daniel J., Zoltán Haiman, Janna Levin, Johan Samsing, and Alejandro Vigna-Gómez. “Multimessenger Constraints on Magnetic Fields in Merging Black Hole–Neutron Star Binaries.” The Astrophysical Journal.

No coincident electromagnetic (EM) counterparts were detected. While the mass ratio and BH spin in both systems were not sufficient to tidally disrupt the NS outside the BH event horizon, other, magnetospheric mechanisms for EM emission exist in this regime and depend sensitively on the NS magnetic field strength. Combining GW measurements with EM flux upper limits, we place upper limits on the NS surface magnetic field strength above which magnetospheric emission models would have generated an observable EM counterpart. We consider fireball models powered by the black hole battery mechanism, where energy is output in gamma rays over ≲1 s. Consistency with no detection by Fermi-GBM or INTEGRAL SPI-ACS constrains the NS surface magnetic field to ≲1015 G. Hence, joint GW detection and EM upper limits rule out the theoretical possibility that the NSs in GW200105 and GW200115, and the putative NS in GW190814, retain dipolar magnetic fields ≳1015 G until merger. They also rule out formation scenarios where strongly magnetized magnetars quickly merge with BHs. We alternatively rule out operation of the BH-battery-powered fireball mechanism in these systems. This is the first multimessenger constraint on NS magnetic fields in BHNS systems and a novel approach to probe fields at this point in NS evolution. This demonstrates the constraining power that multimessenger analyses of BHNS mergers have on BHNS formation scenarios, NS magnetic field evolution, and the physics of BHNS magnetospheric interactions."}],"article_number":"56","publication_status":"published","status":"public","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","doi":"10.3847/1538-4357/ac4bdb","issue":"1","extern":"1","oa":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.3847/1538-4357/ac4bdb"}]},{"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","doi":"10.1016/j.actaastro.2022.04.020","day":"06","publication_status":"published","status":"public","main_file_link":[{"url":"https://doi.org/10.1016/j.actaastro.2022.04.020","open_access":"1"}],"extern":"1","oa":1,"intvolume":" 196","scopus_import":"1","article_type":"original","date_created":"2024-09-05T12:19:08Z","volume":196,"abstract":[{"lang":"eng","text":"Ultra-high angular resolution in astronomy has always been an important vehicle for making fundamental discoveries. Recent results in direct imaging of the vicinity of the supermassive black hole in the nucleus of the radio galaxy M87 by the millimeter VLBI system Event Horizon Telescope and various pioneering results of the Space VLBI mission RadioAstron provided new momentum in high angular resolution astrophysics. In both mentioned cases, the angular resolution reached the values of about 10–20 microarcseconds (0.05–0.1 nanoradian). Further developments towards at least an order of magnitude “sharper” values, at the level of 1 microarcsecond are dictated by the needs of advanced astrophysical studies. The paper emphasis that these higher values can only be achieved by placing millimeter and submillimeter wavelength interferometric systems in space. A concept of such the system, called Terahertz Exploration and Zooming-in for Astrophysics, has been proposed in the framework of the ESA Call for White Papers for the Voyage 2050 long term plan in 2019. In the current paper we present new science objectives for such the concept based on recent results in studies of active galactic nuclei and supermassive black holes. We also discuss several approaches for addressing technological challenges of creating a millimeter/sub-millimeter wavelength interferometric system in space. In particular, we consider a novel configuration of a space-borne millimeter/sub-millimeter antenna which might resolve several bottlenecks in creating large precise mechanical structures. The paper also presents an overview of prospective space-qualified technologies of low-noise analogue front-end instrumentation for millimeter/sub-millimeter telescopes. Data handling and processing instrumentation is another key technological component of a sub-millimeter Space VLBI system. Requirements and possible implementation options for this instrumentation are described as an extrapolation of the current state-of-the-art Earth-based VLBI data transport and processing instrumentation. The paper also briefly discusses approaches to the interferometric baseline state vector determination and synchronisation and heterodyning system. The technology-oriented sections of the paper do not aim at presenting a complete set of technological solutions for sub-millimeter (terahertz) space-borne interferometers. Rather, in combination with the original ESA Voyage 2050 White Paper, it sharpens the case for the next generation microarcsecond-level imaging instruments and provides starting points for further in-depth technology trade-off studies."}],"oa_version":"Published Version","language":[{"iso":"eng"}],"publisher":"Elsevier BV","date_updated":"2024-09-19T08:01:42Z","_id":"17576","citation":{"chicago":"Gurvits, Leonid I., Zsolt Paragi, Ricardo I.

Using multiwavelength (MWL) information (optical, X-ray, mid-IR), we characterized the intrinsic nuclear properties of this sample and compared them with those of isolated systems. Among the 124 X-ray-detected AGN candidates, 52 appear in pairs and 72 as single X-ray sources. Through MWL analysis, we confirmed the presence of the AGN in >80 per cent of the detected targets in pairs (42 out of 52). X-ray spectral analysis confirms the trend of increasing AGN luminosity with decreasing separation, suggesting that mergers may have contributed to triggering more luminous AGN. Through X-ray/mid-IR ratio versus X-ray colours, we estimated a fraction of Compton-thin AGN (with 1022 cm−2 < NH < 1024 cm−2) of about 80 per cent, while about 16 per cent are Compton-thick sources (with NH > 1024 cm−2). These fractions of obscured sources are larger than those found in samples of isolated AGN, confirming that pairs of AGN show higher obscuration. This trend is further confirmed by comparing the de-reddened [O iii] emission with the observed X-ray luminosity. However, the derived fraction of Compton-thick sources in this sample at the early stages of merging is lower than that reported for late-merging dual-AGN samples. Comparing NH from X-rays with that derived from E(B − V) from narrow-line regions, we found that the absorbing material is likely to be associated with the torus or broad-line regions. We also explored the X-ray detection efficiency of dual-AGN candidates, finding that, when observed properly (at on-axis positions and with long exposures), X-ray data represent a powerful way to confirm and investigate dual-AGN systems.","lang":"eng"}],"oa_version":"None","publisher":"Oxford University Press","language":[{"iso":"eng"}],"month":"12","citation":{"ieee":"A.

LCs are obtained by modeling the disk thermodynamics with an adiabatic equation of state, a local blackbody cooling prescription, and corrections to approximate the effects of radiation pressure. We find that modulation of multi-band LCs on the orbital time scale are generally in-phase (to within ∼2% of a binary orbital period), but they contain pulse substructure in the time domain that is not necessarily reflected in BH accretion rates M˙. We thus predict that binary-hosting AGN will exhibit highly correlated, in-phase, periodic brightness modulations in their low-energy disk emission. However, detectability of these modulations in multi-wavelength observing campaigns could be seriously compromised because observed stochastic variability in AGNs typically has a higher amplitude than our proposed signal. It is possible that observations over temporal baselines of many binary periods may make the signal more prominent, but this would need to be analyzed carefully. If jet emission is predicted by M˙, then we predict a weaker correlation with low-energy disk emission due to the differing sub-peak structure. For the binary parameters we explore, we show that LC variability due to hydrodynamics likely dominates Doppler brightening for all equal-mass binaries with disk Mach numbers ≲20. A promising signature of eccentricity is weak or absent \"lump\" periodicity. We find hints that a significant lag exists between M˙ and low-energy disk emission for circular binaries, but they are in-phase for eccentric binaries, which might explain some \"orphan\" blazar flares with no γ-ray counterpart."}],"article_number":"103010","oa_version":"Preprint","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","doi":"10.1103/physrevd.106.103010","day":"08","publication_status":"published","status":"public","extern":"1","oa":1,"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2111.06882","open_access":"1"}],"issue":"10","article_processing_charge":"No","quality_controlled":"1","publication_identifier":{"issn":["2470-0010","2470-0029"]},"publication":"Physical Review D","date_published":"2022-11-08T00:00:00Z","type":"journal_article","arxiv":1,"author":[{"first_name":"John Ryan","last_name":"Westernacher-Schneider","full_name":"Westernacher-Schneider, John Ryan"},{"full_name":"Zrake, Jonathan","first_name":"Jonathan","last_name":"Zrake"},{"full_name":"MacFadyen, Andrew","last_name":"MacFadyen","first_name":"Andrew"},{"full_name":"Haiman, Zoltán","first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman"}],"title":"Multiband light curves from eccentric accreting supermassive black hole binaries","language":[{"iso":"eng"}],"publisher":"American Physical Society","date_updated":"2024-09-19T11:36:36Z","_id":"17582","citation":{"chicago":"Westernacher-Schneider, John Ryan, Jonathan Zrake, Andrew MacFadyen, and Zoltán Haiman. “Multiband Light Curves from Eccentric Accreting Supermassive Black Hole Binaries.” Physical Review D.

We investigate protostellar growth in dynamically heated atomic-cooling haloes (ACHs) found in recent cosmological simulations, performing three-dimensional radiation hydrodynamical (RHD) simulations that consider stellar evolution under variable mass accretion. We find that one of the ACHs feeds the central protostar at rates exceeding a critical value, above which the star evolves in a cool bloating phase and hardly produces ionizing photons. Consequently, the stellar mass reaches M∗≳104 M⊙ unimpeded by radiative feedback. In the other ACH, where the mass supply rate is lower, the star spends most of its life as a hot main-sequence star, emitting intense ionizing radiation. Then, the stellar mass growth is terminated around 500 M⊙ by photoevaporation of the circumstellar disk. A series of our RHD simulations provide a formula of the final stellar mass determined either by stellar feedback or their lifetime as a function of the mass supply rate from the parent cloud in the absence of stellar radiation. Combining the results with the statistical properties of SMS-forming clouds in high-redshift quasar progenitor haloes, we construct a top-heavy mass distribution of primordial stars over M∗≃100--105 M⊙, approximately following a power-law spectrum of ∝M−1.3∗ with a steeper decline at M∗≳2×104 M⊙.

Extracting information from these scales requires higher-order statistics and the controlling of related systematics such as baryonic effects. To account for baryonic effects in cosmological analyses at reduced computational cost, semi-analytic baryonic correction models (BCMs) have been proposed. Here, we study the accuracy of a particular BCM (the A20-BCM) for WL peak counts, a well-studied, simple, and effective higher-order statistic. We compare WL peak counts generated from the full hydrodynamical simulation IllustrisTNG and a baryon-corrected version of the corresponding dark matter-only simulation IllustrisTNG-Dark. We apply galaxy shape noise matching depths reached by DES, KiDS, HSC, LSST, Roman, and Euclid. We find that peak counts from the A20-BCM are (i) accurate at per cent level for peaks with S/N < 4, (ii) statistically indistinguishable from IllustrisTNG in most current and ongoing surveys, but (iii) insufficient for deep future surveys covering the largest solid angles, such as LSST and Euclid. We find that the BCM matches individual peaks accurately, but underpredicts the amplitude of the highest peaks. We conclude that the A20-BCM is a viable substitute for full hydrodynamical simulations in cosmological parameter estimation from beyond-Gaussian statistics for ongoing and future surveys with modest solid angles. For the largest surveys, the A20-BCM must be refined to provide a more accurate match, especially to the highest peaks."}],"oa_version":"Preprint"},{"type":"journal_article","date_published":"2022-08-01T00:00:00Z","author":[{"full_name":"Hu, Haojie","last_name":"Hu","first_name":"Haojie"},{"first_name":"Kohei","last_name":"Inayoshi","full_name":"Inayoshi, Kohei"},{"first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman","full_name":"Haiman, Zoltán"},{"last_name":"Quataert","first_name":"Eliot","full_name":"Quataert, Eliot"},{"full_name":"Kuiper, Rolf","last_name":"Kuiper","first_name":"Rolf"}],"title":"Long-term evolution of supercritical black hole accretion with outflows: A subgrid feedback model for cosmological simulations","quality_controlled":"1","publication_identifier":{"issn":["0004-637X","1538-4357"]},"article_processing_charge":"No","publication":"The Astrophysical Journal","year":"2022","citation":{"chicago":"Hu, Haojie, Kohei Inayoshi, Zoltán Haiman, Eliot Quataert, and Rolf Kuiper. “Long-Term Evolution of Supercritical Black Hole Accretion with Outflows: A Subgrid Feedback Model for Cosmological Simulations.” The Astrophysical Journal.

In the high-accretion optically-thick limit, where the radiation energy is efficiently trapped within the inflow, the accretion flow becomes adiabatic and comprises of turbulent gas in the equatorial region and strong bipolar outflows. As a result, the mass inflow rate decreases toward the center as M˙in∝rp with p∼0.5−0.7 and a small fraction of the inflowing gas feeds the nuclear BH. Thus, super-Eddington accretion is sustained only when a larger amount of gas is supplied from larger radii at >100−1000 M˙Edd. The global structure of the flow settles down to a quasi-steady state in millions of the orbital timescale at the BH event horizon, which is >10−100 times longer than that addressed in previous (magneto-)RHD simulation studies. Energy transport via radiative diffusion accelerates the outflow near the poles in the inner region but does not change the overall properties of the accretion flow compared to the cases without diffusion. Based on our simulation results, we provide a mechanical feedback model for super-Eddington accreting BHs. This can be applied as a sub-grid model in large-scale cosmological simulations that do not sufficiently resolve galactic nuclei, and to the formation of the heaviest gravitational-wave sources via accretion in dense environments.","lang":"eng"}],"article_number":"132","article_type":"original","date_created":"2024-09-05T13:17:38Z","volume":934,"oa_version":"Published Version","intvolume":" 934","scopus_import":"1","extern":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.3847/1538-4357/ac75d8"}],"oa":1,"issue":"2","day":"01","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","doi":"10.3847/1538-4357/ac75d8","status":"public","publication_status":"published"},{"file":[{"creator":"dernst","file_id":"7796","checksum":"f53e71fd03744075adcd0b8fc1b8423d","file_size":263926,"date_created":"2020-05-04T10:33:42Z","file_name":"2020_EuropMathematics_Akopyan.pdf","access_level":"open_access","date_updated":"2020-07-14T12:48:03Z","relation":"main_file","content_type":"application/pdf"}],"date_updated":"2025-04-14T07:48:36Z","_id":"7791","citation":{"chicago":"Akopyan, Arseniy, and Roman Karasev. “When Different Norms Lead to Same Billiard Trajectories?” European Journal of Mathematics.

In the same step, the chosen node picks a random neighbor, and the two nodes balance their loads by averaging them. We are interested in the expected gap between the minimum and maximum loads at nodes as the process progresses, and its dependence on n and on the graph structure. Variants of the above graphical balanced allocation process have been studied previously by Peres, Talwar, and Wieder [Peres et al., 2015], and by Sauerwald and Sun [Sauerwald and Sun, 2015]. These authors left as open the question of characterizing the gap in the case of cycle graphs in the dynamic case, where weights are created during the algorithm’s execution. For this case, the only known upper bound is of 𝒪(n log n), following from a majorization argument due to [Peres et al., 2015], which analyzes a related graphical allocation process. In this paper, we provide an upper bound of 𝒪 (√n log n) on the expected gap of the above process for cycles of length n. We introduce a new potential analysis technique, which enables us to bound the difference in load between k-hop neighbors on the cycle, for any k ≤ n/2. We complement this with a \"gap covering\" argument, which bounds the maximum value of the gap by bounding its value across all possible subsets of a certain structure, and recursively bounding the gaps within each subset. We provide analytical and experimental evidence that our upper bound on the gap is tight up to a logarithmic factor.
