While Bitcoin,\r\nbased on Proof-of-Work (PoW), was the first protocol in this model, significant\r\nresearch has focused on permissionless protocols using alternative physical resources,\r\nspecifically Proof-of-Space (PoSpace) and Verifiable Delay Functions (VDFs). This\r\nthesis investigates the theoretical limits and design space of longest-chain protocols in\r\nthe fully permissionless and dynamically available settings using these three resources.\r\nFirst, we address the feasibility of blockchains relying solely on storage as a resource.\r\nWe prove a fundamental impossibility result: there exists no secure longest-chain\r\nprotocol based exclusively on Proof-of-Space in the fully permissionless or dynamically\r\navailable settings. Further, we quantify the adversarial capabilities required to execute\r\na double-spend attack. Our result formally justifies the necessity of coupling PoSpace\r\nwith time-dependent primitives (such as VDFs) or to move to less permissive settings\r\n(quasi-permissionless or permissioned) to ensure security.\r\nSecond, we generalize Nakamoto-like heaviest chain consensus to protocols utilizing\r\ncombinations of multiple physical resources. We analyze chain selection rules governed\r\nby a weight function Γ(S, V,W), which assigns weight to blocks based on recorded\r\nSpace (S), VDF speed (V ), and Work (W). We provide a complete classification\r\nof secure weight functions, proving that a weight function is secure against private\r\ndouble-spend attacks if and only if it is homogeneous in the timed resources (V,W)\r\nand sub-homogeneous in S. This framework unifies existing protocols like Bitcoin and\r\nChia under a single theoretical model and provides a powerful tool for designing new\r\nlongest-chain blockchains from a mix of physical resources.","lang":"eng"}],"file_date_updated":"2026-04-15T07:37:25Z","citation":{"ieee":"M.

Our analysis focuses on tropical precipitation characteristics spanning a wide range of spatio-temporal scales—including the diurnal cycle, extreme precipitation, convective organization, and the Madden-Julian Oscillation (MJO)—along with interactions between convection and the thermodynamic environment. All three models commonly show weaker convective organization with smaller precipitation cells than observed, though the strength of the bias varies by model. This diversity is introduced by differences in the representation of (a) convective initiation affected by the convective sensitivity to moisture and (b) tropospheric moistening associated with deep convection. Models with stronger thermodynamic-convection coupling increase environmental moisture near convection, thereby enhancing convective organization. This has important upscale effects on the MJO; while IFS and NICAM capture its eastward propagation well, ICON has difficulty reproducing it. The amplitudes and phases of precipitation diurnal cycles over land show much greater disagreement among the models than over ocean, influenced by how convection is initiated. Biases in rain evaporation and cold pool formation hinder the propagation of mesoscale convection, leading to errors such as the misrepresentation of nocturnal convection moving off the coast of Sumatra in IFS and ICON. These results highlight the importance of thermodynamic-convection coupling in realistically simulating tropical convection across scales. To improve this coupling, kilometer-scale models require better representation of the interaction between resolved convection and three-dimensional turbulent mixing."}],"publication_identifier":{"eissn":["1942-2466"]},"volume":18,"language":[{"iso":"eng"}],"file_date_updated":"2026-04-07T09:11:23Z","citation":{"ieee":"D.

In particular, the ability of these envelope gravito-inertial modes to couple with those trapped in the radiative interior could open up new opportunities for probing the deep-layer dynamics of solar-type stars. The possibility for such a coupling to occur is particularly favoured among pre-main-sequence (PMS) solar-type stars. Indeed, due to the contraction of the protostellar object, they are able to reach high rotation frequencies before nuclear reactions are ignited and magnetic braking becomes the driving mechanism for their rotational evolution. In this work, we studied the coupling between the envelope inertial waves and the radiative interior g modes in PMS stars, focussing on the case of prograde dipolar modes. We considered the cases of 0.5 M⊙ and 1 M⊙ PMS models, each with three different scenarios of rotational evolution. We show that for stars that have formed with a sufficient amount of angular momentum, this coupling can occur in frequency ranges that are accessible to space-borne photometry, creating inertial dips in the period spacing pattern. Using an asymptotic analysis, we characterised the shape of these inertial dips to show that they depend on rotation and on the stiffness of the convective-radiative interface.","lang":"eng"}],"date_updated":"2026-04-07T09:23:27Z","publication_identifier":{"issn":["0004-6361"],"eissn":["1432-0746"]},"DOAJ_listed":"1","has_accepted_license":"1","title":"Core-envelope coupling of gravito-inertial waves in pre-main-sequence solar-type stars","ddc":["520"],"OA_place":"publisher","OA_type":"diamond","type":"journal_article","scopus_import":"1","publication":"Astronomy & Astrophysics","date_published":"2026-03-01T00:00:00Z","publication_status":"published","file":[{"date_updated":"2026-04-07T09:20:02Z","content_type":"application/pdf","creator":"dernst","file_id":"21666","access_level":"open_access","relation":"main_file","file_size":1535506,"success":1,"date_created":"2026-04-07T09:20:02Z","file_name":"2026_AstronomyAstrophysics_Breton.pdf","checksum":"a7fd798bf450d67d4166fdf54ff2c70c"}],"oa_version":"Published Version","external_id":{"arxiv":["2603.01979"]},"author":[{"last_name":"Breton","full_name":"Breton, S.

Popular algorithms are policy iteration and variants of value iteration; in tool competitions, most participants rely on the latter. These algorithms generally need worst-case exponential time. However, the problem can equally be formulated as a linear programme, solvable in polynomial time. In this paper, we give a detailed overview of today’s state-of-the-art algorithms for MDP model checking with a focus on performance and correctness. We highlight their fundamental differences, and describe various optimizations and implementation variants. We experimentally compare floating-point and exact-arithmetic implementations of all algorithms on three benchmark sets using two probabilistic model checkers. Our results show that (optimistic) value iteration is a sensible default, but other algorithms are preferable in specific settings. This paper thereby provides a guide for MDP verification practitioners—tool builders and users alike.","lang":"eng"}],"quality_controlled":"1","year":"2026","keyword":["Quantitative model checking","Markov decision process","Linear programming","Value iteration","Policy iteration"],"month":"03","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","department":[{"_id":"KrCh"}],"article_type":"original","tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"publication_status":"epub_ahead","oa_version":"Published Version","author":[{"full_name":"Hartmanns, Arnd","first_name":"Arnd","last_name":"Hartmanns"},{"last_name":"Junges","full_name":"Junges, Sebastian","first_name":"Sebastian"},{"last_name":"Quatmann","full_name":"Quatmann, Tim","first_name":"Tim"},{"last_name":"Weininger","orcid":"0000-0002-0163-2152","id":"02ab0197-cc70-11ed-ab61-918e71f56881","first_name":"Maximilian","full_name":"Weininger, Maximilian"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1007/s10009-026-00848-y"}],"project":[{"name":"IST-BRIDGE: International postdoctoral program","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","grant_number":"101034413","call_identifier":"H2020"}]},{"oa_version":"Preprint","status":"public","article_processing_charge":"No","day":"14","publication_status":"submitted","_id":"21699","date_created":"2026-04-09T09:10:41Z","oa":1,"abstract":[{"lang":"eng","text":"Recent research in nanophotonics for scintillation-based imaging has demonstrated promising improvements in scintillator performance. In parallel, advances in nanophotonics have enabled wavefront control through metasurfaces, a capability that has transformed fields such as microscopy by allowing tailored control of optical propagation. This naturally raises the following question, which we address in this perspective: can wavefront-control strategies be leveraged to improve scintillation-based imaging? To answer this question, we explore nanophotonic- and metasurface-enabled wavefront control in scintillators to mitigate image blurring arising from their intrinsically diffuse light emission. While depth-of-field extension in scintillation faces fundamental limitations absent in microscopy, this approach reveals promising avenues, including stacked scintillators, selective spatial-frequency enhancement, and X-ray energy-dependent imaging. These results clarify the key distinctions in adapting wavefront engineering to scintillation and its potential to enable tailored detection strategies."}],"date_updated":"2026-04-13T11:26:08Z","author":[{"last_name":"Chen","full_name":"Chen, Joshua","first_name":"Joshua"},{"full_name":"Vaidya, Sachin","first_name":"Sachin","last_name":"Vaidya"},{"first_name":"Simo","full_name":"Pajovic, Simo","last_name":"Pajovic"},{"last_name":"Choi","first_name":"Seou","full_name":"Choi, Seou"},{"full_name":"Michaels, William","first_name":"William","last_name":"Michaels"},{"last_name":"Louis Martin-Monier","first_name":"Louis Martin-Monier","full_name":"Louis Martin-Monier, Louis Martin-Monier"},{"full_name":"Hu, Juejun","first_name":"Juejun","last_name":"Hu"},{"last_name":"Cogswell","full_name":"Cogswell, Carol","first_name":"Carol"},{"full_name":"Roques-Carmes, Charles","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","first_name":"Charles","last_name":"Roques-Carmes"},{"last_name":"Soljačić","full_name":"Soljačić, Marin","first_name":"Marin"}],"doi":"10.48550/arXiv.2601.09830","citation":{"short":"J.

Applied strain has attracted particular attention as a key tuning parameter for altermagnets. Although several experimental studies have demonstrated the preparation of single-domain states through a combination of applied strain and magnetic field, the route to such states remains unclear. Here, we use magneto-optical measurements on single crystals of MnTe under applied strain to show that, in contrast to previous reports, strain acts primarily to rotate the Néel vector L continuously. Since the orientation of L determines the magnetic point group symmetry, this continuous rotation effectively tunes the symmetry and its associated physical properties. Furthermore, we demonstrate that built-in strain in free-standing crystals is sufficient to pin L into continuous textures over millimeter length scales. Together, these results provide guidance for future device design and open the door to leveraging the Néel vector orientation as a tunable degree of freedom in spintronic applications."}]},{"scopus_import":"1","type":"journal_article","date_published":"2026-04-07T00:00:00Z","publication":"Proceedings of the National Academy of Sciences","ddc":["570"],"OA_place":"publisher","has_accepted_license":"1","title":"Descent from a common ancestor restricts exploration of protein sequence space","OA_type":"hybrid","file_date_updated":"2026-05-04T06:46:31Z","doi":"10.1073/pnas.2532018123","citation":{"ieee":"L.

However, this question is understudied in part because experimental and computational studies use extant sequences as a starting point to study sequence space. Here, we study whether extant sequences are representative of the entire functional sequence space. Across thousands of protein families from vertebrates and bacteria we calculate the dimensionality and the volume of sequence space occupied by extant homologs. We find that the observed dimensionality and volume of extant sequence space are minuscule, many orders of magnitude smaller than what we estimated using a model of protein evolution. Simulating sequence evolution we then quantify the impact of phylogeny, selection, and epistasis on restricting the evolutionary exploration of sequence space. We find that sequence evolution from a single common ancestor, or a single point of origin in sequence space, is by far the largest limiting factor that reduces the dimensionality and volume of extant sequence space. These results indicate that there are vast areas of functional sequence space that have not been explored in evolution because of the excessive restrictions on natural exploration of the protein sequence space imposed by the point of origin effect. We suggest that protein design methods that rely on extant sequences may be limited in their ability to discover truly novel functions.","lang":"eng"}],"date_updated":"2026-05-04T06:57:31Z","publisher":"National Academy of Sciences","day":"07","_id":"21704","license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","date_created":"2026-04-12T22:01:47Z","oa":1,"status":"public","acknowledgement":"We thank Olga Kalinina for feedback on our manuscript, Vsevolod Kuksin for fruitful discussions and Lev Tsarin for participation in the design of our models.

Follow-up with the Large Lenslet Array Magellan Spectrograph shows a helium-dominated accretion disk, and high-speed ULTRACAM photometry reveals pronounced primary and secondary eclipses. We construct a decade-long timing baseline leveraging light curves from the ATLAS and Gaia surveys, as well as the high-speed imagers ULTRACAM on the New Energy Telescope and proto-Lightspeed on the Magellan Clay telescope. From this timing baseline, we measure an orbital period derivative of P 1.60 0.07 10 = ± × 12 s s−1. Interpreted in the context of stable mass transfer, the magnitude and sign of P indicate that the orbital evolution is governed by the interplay between gravitationalwave-driven angular-momentum losses and mass transfer, directly probing the donor’s structural response to mass loss. We constrain the accretor and donor mass based on stable mass-transfer arguments assuming angularmomentum loss dominated by gravitational-wave emission, allowing us to infer the characteristic gravitational\r\nwave strain of the binary for future space-based GW observatories such as the Laser Interferometer Space Antenna (LISA). We predict a characteristic strain corresponding to a 4 yr LISA signal-to-noise ratio ≳10, establishing ATLAS J1013−4516 as a strong prospective LISA source that will probe long-term orbital evolution in the mass-transferring regime.","lang":"eng"}],"_id":"21705","publisher":"IOP Publishing","day":"01","oa":1,"date_created":"2026-04-12T22:01:47Z","article_processing_charge":"Yes","status":"public","acknowledgement":"This work has made use of data from the Asteroid Terrestrial-impact Last Alert System (ATLAS) project.

How neuronal left-right asymmetry is initiated and integrated into a bilaterally symmetrical ground pattern is poorly understood. Here, we show that the directional asymmetry of a Drosophila central brain circuit originates from axonal interactions of two types of bilateral pioneer neurons. Subsequent recruitment of neighboring neurons into the asymmetric neuropil primordium results in hemisphere-specific microcircuits. Circuit lateralization requires dynamic expression of the cell adhesion molecule Fasciclin 2 to maintain structural plasticity in axonal remodeling. Reduced circuit asymmetry following cell type–specific Fasciclin 2 manipulation affects adult brain function. These results reveal an unexpected degree of developmental plasticity of late-born Drosophila neurons in the formation of a circuit node via the lateralized recruitment of symmetric circuit components."}],"date_updated":"2026-05-04T09:18:06Z","publication_identifier":{"eissn":["2375-2548"]},"language":[{"iso":"eng"}],"volume":12,"doi":"10.1126/sciadv.aea6020","file_date_updated":"2026-05-04T09:16:36Z","citation":{"ista":"Markovitsch JW, Mitić D, Del Pilar Jiménez García A, Zane A, Kainz S, Kaur R, Hummel T. 2026.

The GLOF also destroyed 13 bridges and a major hydropower plant in the Chungthang region. Over 60,000 individuals in four districts of Sikkim were impacted by this GLOF event. This study examines the factors that led to the GLOF event. Our study shows that the cause of this GLOF was initiated by a landslide, that dumped a substantial amount (~ 38.31 million m3) of debris into the South Lhonak Lake. Furthermore, the glacier that was connected to the lake, lost a big chunk of ice mass (~ 7 million m3) due to calving. The combination of these two processes led to the collapse of the left lateral moraine that consequently generated flood waves which breached the terminal moraine dam of the lake. We recommend monitoring land subsidence and calving events for large proglacial lakes to prevent the disastrous consequences of such GLOFs in the future.","lang":"eng"}],"date_updated":"2026-05-04T07:54:53Z","publication_identifier":{"eissn":["2045-2322"]},"corr_author":"1","oa":1,"date_created":"2026-04-12T22:01:48Z","publisher":"Springer Nature","day":"24","_id":"21708","status":"public","acknowledgement":"This work was carried out independently without the support of any funding agency or sponsors.

Key questions are how LRDs connect to standard UV-luminous AGN, whether transitional phases exist, and whether they are observable. We present the “X-ray dot” (XRD), a compact source at z = 3.28 observed by the NIRSpec Wide Guaranteed Time Observation survey. The XRD exhibits LRD hallmarks: a blackbody-like (Teff ≃ 6400 K) red continuum, a faint but blue rest-UV excess, falling mid-IR emission, and broad Balmer lines (FWHM ∼ 2700–3200 km s−1). Unlike LRDs, however, it is remarkably X-ray luminous (L2−10 keV = 1044.18 erg s−1) and has a continuum inflection that is blueward of the Balmer limit. We find that the red rest-optical and blue mid-IR continuum cannot be reproduced by standard dust-attenuated AGN models without invoking extremely steep extinction curves, nor can the weak mid-IR emission be reconciled with well-established X-ray–torus scaling relations. We therefore consider an alternative scenario: the XRD may be an LRD in transition, where the gas envelope dominates the optical continuum but optically thin sight lines allow X-rays to escape. The XRD may thus provide a physical link between LRDs and standard AGN, offering direct evidence that LRDs are powered by supermassive black holes and providing insight into their accretion properties.","lang":"eng"}],"date_updated":"2026-05-04T07:13:07Z","citation":{"ieee":"R.

We study this problem using JWST imaging and prism spectroscopy for 412 galaxies at 4.5 < z < 9.0. We fit these data simultaneously with stellar population and nebular emission models that include a parameter for the fraction of ionizing photons that escape the galaxy, fesc. We find that the ionization production efficiency, ξion = Q(H0)/LUV, increases with redshift and decreasing UV luminosity, but shows significant scatter, (log ion z, MUV) 0.3 dex. The inferred escape fractions averaged over the population are low, ranging from〈fesc〉 ≃ 2.6% ± 1.4% at 6 < z < 9 to 6.5% ± 2.2% at 4.5 < z < 6, with weak or no indication of evolution with redshift. This implies that in our models most of the ionizing photons need to be absorbed to account for the nebular emission. We compute the impact of our results on reionization, including the distributions for ξion and fesc, and the evolution and uncertainty of the UV luminosity function. Considering galaxies brighter than MUV < −16 mag would produce an intergalactic medium hydrogen-ionized fraction of xe = 0.5 at 5.3 < z < 5.8, possibly too late compared to constraints from from quasistellar\r\nobject (QSO) sight lines. Including fainter galaxies, MUV < −14 mag, we obtain xe = 0.5 at 6.0 < z < 8.1, fully consistent with QSO and cosmic microwave background data. This implies that EoR galaxies produce plenty of ionizing photons, but that these do not efficiently escape. This may be a result of high gas column densities combined with burstier star formation histories, which limit the time massive stars are able to clear channels through the gas for ionizing photons to escape.","lang":"eng"}],"date_updated":"2026-05-04T10:44:57Z","ddc":["520"],"OA_place":"publisher","has_accepted_license":"1","title":"Galaxies in the epoch of reionization are all bark and no bite-plenty of ionizing photons, low escape fractions","OA_type":"gold","scopus_import":"1","type":"journal_article","date_published":"2026-03-20T00:00:00Z","publication":"The Astrophysical Journal","publication_status":"published","oa_version":"Published Version","file":[{"creator":"dernst","access_level":"open_access","file_id":"21791","file_size":6670398,"relation":"main_file","success":1,"date_created":"2026-05-04T10:40:07Z","file_name":"2026_AstrophysicalJour_Papovich.pdf","checksum":"0031a6f197a3fa8c2845de10b6bdc696","date_updated":"2026-05-04T10:40:07Z","content_type":"application/pdf"}],"author":[{"last_name":"Papovich","full_name":"Papovich, Casey","first_name":"Casey"},{"full_name":"Cole, Justin W.","first_name":"Justin W.","last_name":"Cole"},{"full_name":"Hu, Weida","first_name":"Weida","last_name":"Hu"},{"full_name":"Finkelstein, Steven L.","first_name":"Steven L.","last_name":"Finkelstein"},{"first_name":"Lu","full_name":"Shen, Lu","last_name":"Shen"},{"last_name":"Arrabal Haro","full_name":"Arrabal Haro, Pablo","first_name":"Pablo"},{"full_name":"Amorín, Ricardo O.","first_name":"Ricardo O.","last_name":"Amorín"},{"last_name":"Backhaus","first_name":"Bren E.","full_name":"Backhaus, Bren E."},{"full_name":"Bagley, Micaela B.","first_name":"Micaela B.","last_name":"Bagley"},{"last_name":"Bhatawdekar","full_name":"Bhatawdekar, Rachana","first_name":"Rachana"},{"full_name":"Calabrò, Antonello","first_name":"Antonello","last_name":"Calabrò"},{"last_name":"Carnall","full_name":"Carnall, Adam C.","first_name":"Adam C."},{"first_name":"Nikko J.","full_name":"Cleri, Nikko J.","last_name":"Cleri"},{"first_name":"Emanuele","full_name":"Daddi, Emanuele","last_name":"Daddi"},{"last_name":"Dickinson","full_name":"Dickinson, Mark","first_name":"Mark"},{"last_name":"Grogin","first_name":"Norman A.","full_name":"Grogin, Norman A."},{"last_name":"Holwerda","first_name":"Benne W.","full_name":"Holwerda, Benne W."},{"first_name":"Anne E.","full_name":"Jaskot, Anne E.","last_name":"Jaskot"},{"first_name":"Anton M.","full_name":"Koekemoer, Anton M.","last_name":"Koekemoer"},{"last_name":"Llerena","full_name":"Llerena, Mario","first_name":"Mario"},{"full_name":"Lucas, Ray A.","first_name":"Ray A.","last_name":"Lucas"},{"last_name":"Mascia","first_name":"Sara","id":"edaf889c-c7cd-11ef-ab1b-bb28c431bd29","full_name":"Mascia, Sara"},{"last_name":"Pacucci","full_name":"Pacucci, Fabio","first_name":"Fabio"},{"last_name":"Pentericci","first_name":"Laura","full_name":"Pentericci, Laura"},{"last_name":"Pérez-González","first_name":"Pablo G.","full_name":"Pérez-González, Pablo G."},{"full_name":"Pirzkal, Nor","first_name":"Nor","last_name":"Pirzkal"},{"last_name":"Raghunathan","first_name":"Srinivasan","full_name":"Raghunathan, Srinivasan"},{"last_name":"Seillé","full_name":"Seillé, Lise Marie","first_name":"Lise Marie"},{"full_name":"Somerville, Rachel S.","first_name":"Rachel S.","last_name":"Somerville"},{"first_name":"L.

They enable higher sample loading, improve chromatographic performance, and protect the analytical column by removing salts and contaminants. Recently, monolithic trap columns with micropillar architecture have emerged as alternatives to conventionally packed traps. This study compares the performance of a packed and a micropillar monolithic trap column for the analysis of tryptic peptides. Methods: A tryptic digest of HeLa cell lysate was analyzed under identical LC–MS conditions using both trap types. Peptides were detected at 214 nm and analyzed by nano-ESI on a Q Exactive Plus Orbitrap. Data were searched against the human UniProt database (February 2023) using FragPipe v20.0, and statistical evaluation of MaxLFQ intensities was performed in Perseus using Welch’s t-test and clustering analysis. Results: Over 2500 proteins were identified with both setups. The packed trap column yielded more total peptides, particularly those with post-translational modifications and higher hydrophilicity, whereas the monolithic column favored peptides of intermediate hydrophobicity. Chromatographic profiles confirmed a slight reduction in the trapping efficiency of hydrophilic peptides by the monolithic trap. Conclusions: Trap column design significantly influences peptide recovery and proteome coverage.","lang":"eng"}],"date_updated":"2026-05-04T10:36:21Z","doi":"10.3390/proteomes14010010","file_date_updated":"2026-05-04T10:31:35Z","citation":{"ieee":"J.

At subparsec separations, SMBHBs can be identified as quasars with periodic variability, with previous periodicity searches uncovering significant candidates. However, these searches focused primarily on sinusoidal signals, while theoretical models and hydrodynamical simulations predict that binaries produce more complex non-sinusoidal pulse shapes. Here we examine the efficacy of the Lomb–Scargle periodogram (LSP; one of the most popular tools for periodicity searches in unevenly sampled lightcurves) to detect periodicities with a sawtooth shape mimicking results of hydrodynamical simulations. We simulate idealized well-sampled lightcurves, lightcurves that mimic the data in the Palomar Transient Factory (PTF) analyzed in M. Charisi et al. (2016), and lightcurves that resemble our expectations for single-band data in the upcoming Legacy Survey of Space and Time (LSST) of the Rubin Observatory. We approximate quasar variability with a damped random walk (DRW) model, inject sinusoidal and sawtooth pulse shapes, and assess their statistical significance. We find that in the presence of red noise, the LSP detects a relatively low fraction of the sinusoidal signals (∼45%, ∼24%, and ∼23%, in the PTF-like, idealized, and LSST-like lightcurves, respectively). The fraction is significantly reduced for sawtooth periodicity (with only ∼9% in PTF-like and ∼1% in idealized and LSST-like lightcurves). These low recovery rates imply that previous searches have missed the large majority of binaries. They also have significant implications for the detection of SMBHBs in upcoming LSST necessitating the development of advanced tools that go beyond the simple LSP.","lang":"eng"}],"date_updated":"2026-05-04T10:26:59Z","publication_identifier":{"issn":["0004-637X"],"eissn":["1538-4357"]},"date_created":"2026-04-12T22:01:49Z","oa":1,"day":"01","publisher":"IOP Publishing","_id":"21712","status":"public","acknowledgement":"M.C. acknowledges support by the European Union (ERC; MMMonsters, 101117624).

Here we show that the black hole spin vectors are closely aligned with each other while significantly tilted relative to the binary’s orbital angular momentum, pointing to a common accretion-driven origin. We examine astrophysical formation channels capable of producing near-equal, high-mass, and mutually aligned spins consistent with GW231123—particularly binaries embedded in AGN disks and Population III remnants, which grew via coherent misaligned gas accretion. We further argue that other high-mass, high-spin events, e.g., GW190521, may share a similar evolutionary pathway.

In this Letter, we propose a new formation scenario for black hole (BH) + Be star binaries (hereafter BHBe binaries), where the Be star is produced through the wind Roche lobe overflow (WRLOF) mechanism. Our analysis is based on numerical simulations of the WRLOF process in massive binaries, building on recent theoretical work. We demonstrate that the WRLOF model can efficiently form BHBe binaries under reasonable assumptions on stellar wind velocities. Using rapid binary population synthesis, we estimate the population of such systems in the Milky Way, predicting ∼1800−3200 currently existing BHBe binaries originating from the WRLOF channel. These systems are characterized by high eccentricities and exceptionally wide orbits, with typical orbital periods exceeding 1000 days and a peak distribution around ∼10,000 days. Due to their long orbital separations, these BHBe binaries are promising targets for future detection via astrometric and interferometric observations."}],"date_updated":"2026-04-16T06:26:18Z","citation":{"apa":"Li, Z., Jia, S., Wei, D., Ge, H., Chen, H., Zhang, Y., … Han, Z.

Leveraging X-ray through far-infrared observations of two of the most luminous known little red dots, we directly measure their bolometric luminosities. We find evidence that more than half of the bolometric luminosity likely emerges in the rest-frame optical, with Lbol/L5100 = 5, roughly half the value for “standard” active galactic nuclei. Meanwhile, the X-ray emitting corona, UV-emitting blackbody, and reprocessed mid to far-infrared emission are all considerably subdominant, assuming that the far-infrared luminosity is well below current measured limits. We present new bolometric corrections that dramatically lower inferred bolometric luminosities by a factor of 10 compared to published values in the literature. These bolometric corrections are in accord with expectations from models in which gas absorption and reprocessing are responsible for the red rest-frame optical colors of little red dots. We discuss how this lowered luminosity scale suggests a lower mass scale for the population by at least an order of magnitude (e.g., ∼105–107 M⊙ black holes, and ∼108 M⊙ galaxies), alleviating tensions with clustering, overmassive black holes, and the integrated black hole mass density in the Universe."}],"date_updated":"2026-05-04T11:20:42Z","publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"language":[{"iso":"eng"}],"volume":996,"file_date_updated":"2026-05-04T11:19:48Z","citation":{"apa":"Greene, J.
