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."}],"publisher":"IOP Publishing","scopus_import":"1","date_created":"2026-04-12T22:01:48Z","tmp":{"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)","image":"/images/cc_by.png"},"OA_place":"publisher","_id":"21709","ddc":["520"],"quality_controlled":"1","status":"public","oa":1,"publication":"The Astrophysical Journal Letters","month":"03","oa_version":"Published Version","doi":"10.3847/2041-8213/ae4c88","file":[{"checksum":"1be4f361bf59aa08b8c98ed4f475a463","content_type":"application/pdf","file_size":2821786,"file_id":"21784","access_level":"open_access","relation":"main_file","date_created":"2026-05-04T07:11:37Z","date_updated":"2026-05-04T07:11:37Z","success":1,"file_name":"2026_AstrophysicalJourLetters_Hviding.pdf","creator":"dernst"}],"author":[{"full_name":"Hviding, Raphael E.","last_name":"Hviding","first_name":"Raphael E."},{"first_name":"Anna","full_name":"De Graaff, Anna","last_name":"De Graaff"},{"first_name":"Hanpu","last_name":"Liu","full_name":"Liu, Hanpu"},{"first_name":"Andy D.","last_name":"Goulding","full_name":"Goulding, Andy D."},{"full_name":"Ma, Yilun","last_name":"Ma","first_name":"Yilun"},{"full_name":"Greene, Jenny E.","last_name":"Greene","first_name":"Jenny E."},{"full_name":"Boogaard, Leindert A.","last_name":"Boogaard","first_name":"Leindert A."},{"full_name":"Bunker, Andrew J.","last_name":"Bunker","first_name":"Andrew J."},{"full_name":"Cleri, Nikko J.","last_name":"Cleri","first_name":"Nikko J."},{"last_name":"Franx","full_name":"Franx, Marijn","first_name":"Marijn"},{"first_name":"Michaela","full_name":"Hirschmann, Michaela","last_name":"Hirschmann"},{"full_name":"Leja, Joel","last_name":"Leja","first_name":"Joel"},{"id":"7439a258-f3c0-11ec-9501-9df22fe06720","first_name":"Jorryt J","full_name":"Matthee, Jorryt J","orcid":"0000-0003-2871-127X","last_name":"Matthee"},{"first_name":"Rohan P.","last_name":"Naidu","full_name":"Naidu, Rohan P."},{"full_name":"Setton, David J.","last_name":"Setton","first_name":"David J."},{"first_name":"Hannah","full_name":"Übler, Hannah","last_name":"Übler"},{"last_name":"Venturi","full_name":"Venturi, Giacomo","first_name":"Giacomo"},{"first_name":"Bingjie","last_name":"Wang","full_name":"Wang, Bingjie"}],"external_id":{"arxiv":["2601.09778"]},"DOAJ_listed":"1","arxiv":1,"intvolume":" 1000","article_number":"L18","publication_status":"published","issue":"1"},{"ddc":["520"],"quality_controlled":"1","publication":"The Astrophysical Journal","month":"03","oa":1,"status":"public","publisher":"IOP Publishing","article_type":"original","acknowledgement":"We wish to thank our colleagues in the CEERS collaboration for their hard work and valuable contributions on this project.

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."}],"OA_place":"publisher","tmp":{"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)","image":"/images/cc_by.png"},"_id":"21710","scopus_import":"1","date_created":"2026-04-12T22:01:49Z","title":"Galaxies in the epoch of reionization are all bark and no bite-plenty of ionizing photons, low escape fractions","citation":{"ista":"Papovich C, Cole JW, Hu W, Finkelstein SL, Shen L, Arrabal Haro P, Amorín RO, Backhaus BE, Bagley MB, Bhatawdekar R, Calabrò A, Carnall AC, Cleri NJ, Daddi E, Dickinson M, Grogin NA, Holwerda BW, Jaskot AE, Koekemoer AM, Llerena M, Lucas RA, Mascia S, Pacucci F, Pentericci L, Pérez-González PG, Pirzkal N, Raghunathan S, Seillé LM, Somerville RS, Yung LYA. 2026.

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.

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"}],"article_type":"original","OA_place":"publisher","tmp":{"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)","image":"/images/cc_by.png"},"_id":"21712","scopus_import":"1","date_created":"2026-04-12T22:01:49Z","quality_controlled":"1","ddc":["520"],"publication":"The Astrophysical Journal","month":"02","oa":1,"status":"public","language":[{"iso":"eng"}],"date_published":"2026-02-01T00:00:00Z","has_accepted_license":"1","department":[{"_id":"ZoHa"}],"file_date_updated":"2026-05-04T10:24:49Z","date_updated":"2026-05-04T10:26:59Z","day":"01","year":"2026","type":"journal_article","publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"title":"Lomb-scargle periodogram struggles with non-sinusoidal supermassive Black Hole binary signatures in quasar lightcurves","citation":{"chicago":"Lin, Allison, Maria Charisi, and Zoltán Haiman. “Lomb-Scargle Periodogram Struggles with Non-Sinusoidal Supermassive Black Hole Binary Signatures in Quasar Lightcurves.” The Astrophysical Journal.

The component spins are both exceptionally high (a1 = 0.90 +0.10/-0.19, a2 = 0.80 +0.20/-0.51), which is difficult to explain with repeated mergers. 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. These findings underscore the critical role of sustained, coherent accretion in shaping the most extreme black hole binaries.","lang":"eng"}],"article_type":"original","acknowledgement":"The authors thank Davide Gerosa and Matthew Mould for valuable suggestions.

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.","lang":"eng"}],"tmp":{"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)","image":"/images/cc_by.png"},"_id":"21714","OA_place":"publisher","date_created":"2026-04-12T22:01:50Z","scopus_import":"1"},{"arxiv":1,"article_number":"129","publication_status":"published","issue":"2","PlanS_conform":"1","intvolume":" 996","doi":"10.3847/1538-4357/ae1836","author":[{"last_name":"Greene","full_name":"Greene, Jenny E.","first_name":"Jenny E."},{"full_name":"Setton, David J.","last_name":"Setton","first_name":"David J."},{"full_name":"Furtak, Lukas J.","last_name":"Furtak","first_name":"Lukas J."},{"full_name":"Naidu, Rohan P.","last_name":"Naidu","first_name":"Rohan P."},{"first_name":"Marta","full_name":"Volonteri, Marta","last_name":"Volonteri"},{"last_name":"Dayal","full_name":"Dayal, Pratika","first_name":"Pratika"},{"last_name":"Labbe","full_name":"Labbe, Ivo","first_name":"Ivo"},{"first_name":"Pieter","last_name":"Van Dokkum","full_name":"Van Dokkum, Pieter"},{"full_name":"Bezanson, Rachel","last_name":"Bezanson","first_name":"Rachel"},{"first_name":"Gabriel","full_name":"Brammer, Gabriel","last_name":"Brammer"},{"first_name":"Sam E.","last_name":"Cutler","full_name":"Cutler, Sam E."},{"full_name":"Glazebrook, Karl","last_name":"Glazebrook","first_name":"Karl"},{"full_name":"De Graaff, Anna","last_name":"De Graaff","first_name":"Anna"},{"last_name":"Hirschmann","full_name":"Hirschmann, Michaela","first_name":"Michaela"},{"first_name":"Raphael E.","full_name":"Hviding, Raphael E.","last_name":"Hviding"},{"full_name":"Kokorev, Vasily","last_name":"Kokorev","first_name":"Vasily"},{"first_name":"Joel","last_name":"Leja","full_name":"Leja, Joel"},{"last_name":"Liu","full_name":"Liu, Hanpu","first_name":"Hanpu"},{"last_name":"Ma","full_name":"Ma, Yilun","first_name":"Yilun"},{"id":"7439a258-f3c0-11ec-9501-9df22fe06720","first_name":"Jorryt J","full_name":"Matthee, Jorryt J","orcid":"0000-0003-2871-127X","last_name":"Matthee"},{"full_name":"Nanayakkara, Themiya","last_name":"Nanayakkara","first_name":"Themiya"},{"last_name":"Oesch","full_name":"Oesch, Pascal A.","first_name":"Pascal A."},{"first_name":"Richard","full_name":"Pan, Richard","last_name":"Pan"},{"full_name":"Price, Sedona H.","last_name":"Price","first_name":"Sedona H."},{"last_name":"Spilker","full_name":"Spilker, Justin S.","first_name":"Justin S."},{"last_name":"Wang","full_name":"Wang, Bingjie","first_name":"Bingjie"},{"first_name":"John R.","last_name":"Weaver","full_name":"Weaver, John R."},{"first_name":"Katherine E.","full_name":"Whitaker, Katherine E.","last_name":"Whitaker"},{"last_name":"Williams","full_name":"Williams, Christina C.","first_name":"Christina C."},{"last_name":"Zitrin","full_name":"Zitrin, Adi","first_name":"Adi"}],"file":[{"date_created":"2026-05-04T11:19:48Z","date_updated":"2026-05-04T11:19:48Z","success":1,"creator":"dernst","file_name":"2026_AstrophysicalJour_Greene.pdf","relation":"main_file","access_level":"open_access","content_type":"application/pdf","file_id":"21792","file_size":684400,"checksum":"7b3cb025d4bcaa35c6e52bd0c8fb6cf4"}],"oa_version":"Published Version","external_id":{"arxiv":["2509.05434"]},"DOAJ_listed":"1","date_created":"2026-04-12T22:01:50Z","scopus_import":"1","OA_place":"publisher","tmp":{"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)","image":"/images/cc_by.png"},"_id":"21715","acknowledgement":"We benefit from the following JWST programs: UNCOVER (JWST/GO #2561; Labbé & Bezanson); ALT (JWST-GO #3516; Naidu & Matthee); MegaScience (JWST-GO #4111; Suess); RUBIES (JWST-GO #4233; de Graaff & Brammer); PRIMER (JWST/GO #1837; Dunlop).\r\n\r\nWe acknowledge funding from NSF/AAG #2306950, JWST-GO-02561, JWST-GO-03516, and JWST-GO-04111, provided through a grant from the STScI under NASA contract NAS5-03127.

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."}],"article_type":"original","publisher":"IOP Publishing","oa":1,"status":"public","month":"01","publication":"The Astrophysical Journal","quality_controlled":"1","ddc":["520"],"year":"2026","publication_identifier":{"issn":["0004-637X"],"eissn":["1538-4357"]},"type":"journal_article","day":"10","date_updated":"2026-05-04T11:20:42Z","file_date_updated":"2026-05-04T11:19:48Z","department":[{"_id":"JoMa"}],"has_accepted_license":"1","language":[{"iso":"eng"}],"date_published":"2026-01-10T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","OA_type":"gold","article_processing_charge":"Yes","volume":996,"project":[{"_id":"bd9b2118-d553-11ed-ba76-db24564edfea","name":"Young galaxies as tracers and agents of cosmic reionization","grant_number":"101076224"}],"citation":{"mla":"Greene, Jenny E., et al. “What You See Is What You Get: Empirically Measured Bolometric Luminosities of Little Red Dots.” The Astrophysical Journal, vol. 996, no. 2, 129, IOP Publishing, 2026, doi:10.3847/1538-4357/ae1836.","ista":"Greene JE, Setton DJ, Furtak LJ, Naidu RP, Volonteri M, Dayal P, Labbe I, Van Dokkum P, Bezanson R, Brammer G, Cutler SE, Glazebrook K, De Graaff A, Hirschmann M, Hviding RE, Kokorev V, Leja J, Liu H, Ma Y, Matthee JJ, Nanayakkara T, Oesch PA, Pan R, Price SH, Spilker JS, Wang B, Weaver JR, Whitaker KE, Williams CC, Zitrin A. 2026.

An objective is a set of runs (or infinite trajectories) of the RMDP, and the value for an objective is the maximal probability that the agent can guarantee against the adversarial environment. We consider (a) reachability objectives, where given a target set of states, the goal is to eventually arrive at one of them; and (b) parity objectives, which are a canonical representation for ω-regular objectives. The qualitative analysis problem asks whether the objective can be ensured with probability 1. In this work, we study the qualitative problem for reachability and parity objectives on RMDPs without making any assumption over the structures of the RMDPs, e.g., unichain or aperiodic. Our contributions are twofold. We first present efficient algorithms with oracle access to uncertainty sets that solve qualitative problems of reachability and parity objectives. We then report experimental results demonstrating the effectiveness of our oracle-based approach on classical RMDP examples from the literature scaling up to thousands of states."}],"ec_funded":1,"publisher":"Association for the Advancement of Artificial Intelligence","oa":1,"status":"public","publication":"Proceedings of the 40th AAAI Conference on Artificial Intelligence","month":"03","quality_controlled":"1"},{"OA_type":"diamond","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","project":[{"_id":"34b2c9cb-11ca-11ed-8bc3-a50ba74ca4a3","name":"Geometry of the tip of the global nilpotent cone","grant_number":"P35847"},{"grant_number":"27483","name":"Big algebras in classical types","_id":"e6c64f42-ab3c-11f0-94c7-a95658059ccc"}],"volume":22,"title":"Big algebra in type A for the coordinate ring of the matrix space","citation":{"ama":"Ngo NT.

For the last three problems, these trade-offs give the first fully-dynamic algorithms achieving poly-logarithmic approximation in sub-linear time per operation.\r\nThe main technical ingredient behind our dynamic hierarchy is a dynamic cut-sparsifier algorithm that can handle vertex splits with low recourse. This is achieved by white-boxing the dynamic cut sparsifier construction of [Abraham et al. FOCS’16], based on forest packing, together with new structural insights about the maintenance of these forests under vertex splits. Given the versatility of cut sparsification in both the static and dynamic graph algorithms literature, we believe this construction may be of independent interest.","lang":"eng"}],"acknowledgement":"Monika Henzinger: Funded by the European union.

The most basic objective is the reachability objective, where a target set must be eventually visited, and the more general parity objectives can model all omega-regular specifications. For such objectives, the computational analysis problems are the following: (a) qualitative analysis that asks whether the objective can be satisfied with probability 1 (almost-sure winning) or probability arbitrarily close to 1 (limit-sure winning); and (b) quantitative analysis that asks for the approximation of the optimal probability of satisfying the objective. For general POMDPs, almost-sure analysis for reachability objectives is EXPTIME-complete, but limit-sure and quantitative analyses for reachability objectives are undecidable; almost-sure, limit-sure, and quantitative analyses for parity objectives are all undecidable. A special class of POMDPs, called revealing POMDPs, has been studied recently in several works, and for this subclass the almost-sure analysis for parity objectives was shown to be EXPTIME-complete. In this work, we show that for revealing POMDPs the limit-sure analysis for parity objectives is EXPTIME-complete, and even the quantitative analysis for parity objectives can be achieved in EXPTIME.","lang":"eng"}],"acknowledgement":"This work was partially supported by the ANRT under the French CIFRE Ph.D program in collaboration between NyxAir and Paris-Dauphine University (Contract: CIFRE N° 2022/0513), by the French Agence Nationale de la Recherche (ANR) under reference ANR-21-CE40-\r\n0020 (CONVERGENCE project), by Austrian Science Fund (FWF) 10.55776/COE12, and by the ERC CoG 863818 (ForM-SMArt) grant.","ec_funded":1,"status":"public","publication":"Proceedings of the AAAI Conference on Artificial Intelligence","month":"03","corr_author":"1","quality_controlled":"1","day":"14","date_updated":"2026-05-04T11:44:14Z","year":"2026","publication_identifier":{"eissn":["2374-3468"],"issn":["2159-5399"]},"type":"conference","date_published":"2026-03-14T00:00:00Z","language":[{"iso":"eng"}],"department":[{"_id":"KrCh"}],"conference":{"name":"AAAI: Conference on Artificial Intelligence","end_date":"2026-01-27","location":"Singapore, Singapore","start_date":"2026-01-20"},"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2511.13134"}],"article_processing_charge":"No","OA_type":"green","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"short":"A.

Open clusters offer the most straightforward way to empirically determine the IFMR, as their well-defined ages allow for direct progenitor lifetime estimates. We construct the most comprehensive open cluster WD IFMR to date by combining new spectroscopy of 22 WDs with an extensive literature review of WDs with strong cluster associations. To minimize systematics, we restrict our analysis to spectroscopically confirmed hydrogen-atmosphere (DA) WDs consistent with single-stellar origins. We separately analyze a subset with reliable Gaia-based astrometric membership assessments, as well as a full sample that adds WDs with strong cluster associations whose membership cannot be reliably assessed with Gaia. The Gaia-based sample includes 69 spectroscopically confirmed DA WDs, more than doubling the sample size of previous Gaia-based open cluster IFMRs. The full sample, which includes 53 additional literature WDs,\r\nincreases the total number of cluster WDs by over 50% relative to earlier works. We provide functional forms for both the Gaia-based and full-sample IFMRs. The Gaia-based result useful for Mi � 2.67 M⊙ is Mf = [0.179 0.100H (Mi 3.84 M )] × (Mi 3.84 M ) + 0.628 M , where H(x) is the Heaviside step function. Comparing our IFMR to recent literature, we identify significant deviations from best-fit IFMRs derived from both Gaia-based volume-limited samples of field WDs and double WD binaries, with the largest discrepancy occurring for initial masses of about 5 M⊙.","lang":"eng"}],"article_processing_charge":"Yes","OA_type":"gold","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"The White Dwarf initial–final mass relation from open clusters in Gaia DR3","citation":{"short":"D.R.

However, molecular markers for centrally projecting PVH neuron populations remain largely undefined, and a complete census of PVH cell types has not been established. Therefore, we performed extensive single-cell/nucleus RNA sequencing to catalog PVH neuron subtypes and multiplexed error-robust fluorescence in situ hybridization (MERFISH) to map them spatially. Our spatial transcriptomic atlas resolves 26 Sim1+ and 29 GABAergic neuron populations from the PVH and surrounding areas. Additionally, projection-based profiling identified neurons that project to the parabrachial region (PB) and spinal cord, helping to determine PVH populations that regulate satiety and sympathetic nervous system activity, respectively. Notably, activation of PB-projecting PVH neurons expressing Brs3 reduces food intake, and silencing them causes obesity. Together, this atlas contributes high-resolution PVH spatial and circuit-based gene expression profiles, representing a valuable resource for the field of homeostasis."}],"article_type":"original","publisher":"Elsevier"},{"intvolume":" 548","article_number":"stag505","publication_status":"published","issue":"1","arxiv":1,"external_id":{"arxiv":["2603.12048"]},"DOAJ_listed":"1","oa_version":"Published Version","doi":"10.1093/mnras/stag505","author":[{"first_name":"Abbigail K.","full_name":"Elms, Abbigail K.","last_name":"Elms"},{"first_name":"Stefano","last_name":"Bagnulo","full_name":"Bagnulo, Stefano"},{"full_name":"Tremblay, Pier Emmanuel","last_name":"Tremblay","first_name":"Pier Emmanuel"},{"full_name":"Cunningham, Tim","last_name":"Cunningham","first_name":"Tim"},{"first_name":"James","full_name":"Munday, James","last_name":"Munday"},{"full_name":"Landstreet, John","last_name":"Landstreet","first_name":"John"},{"first_name":"Kareem","full_name":"El-Badry, Kareem","last_name":"El-Badry"},{"full_name":"Caiazzo, Ilaria","orcid":"0000-0002-4770-5388","last_name":"Caiazzo","id":"8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d","first_name":"Ilaria"},{"full_name":"Melis, Carl","last_name":"Melis","first_name":"Carl"},{"first_name":"Viktoria","full_name":"Pinter, Viktoria","last_name":"Pinter"},{"last_name":"Weinberger","full_name":"Weinberger, Alycia","first_name":"Alycia"}],"file":[{"checksum":"75c48d70d10a9a48875f577e04da80bc","content_type":"application/pdf","file_size":4991495,"file_id":"21794","access_level":"open_access","relation":"main_file","creator":"dernst","file_name":"2026_MNRAS_Elms.pdf","success":1,"date_updated":"2026-05-04T12:10:40Z","date_created":"2026-05-04T12:10:40Z"}],"quality_controlled":"1","ddc":["520"],"oa":1,"status":"public","publication":"Monthly Notices of the Royal Astronomical Society","month":"05","article_type":"original","acknowledgement":"This project has received funding from the European Research Council under the European Union’s Horizon 2020 research and innovation programme (Grant agreement numbers 101002408).

These mysterious systems offer unique insight into the complex interplay between magnetic fields, stellar rotation and atmospheric activity in single white dwarfs. DAHe stars have detectable magnetic fields through Zeeman-split spectral lines, whereas DAe stars lack such splitting. We report the first discovery and characterization of magnetism in the DAe white dwarf WD J165335.21−100116.33 with new time-resolved spectropolarimetry from FORS2. We detect a weak but variable longitudinal magnetic field with values Bz > −9.2 ± 2.4 kG and Bz < −2.2 ± 1.0 kG. Independent ZTF and ATLAS photometry reveal a consistent period of P = 80.3070 ± 0.0007 h. Time-resolved optical spectroscopy obtained with six ground-based instruments demonstrates strong modulation in the strength of the Hα and Hβ Balmer line emission with P = 80.2922 ± 0.0108 h. The photometric flux and Balmer emission strength vary in antiphase, with the strongest magnetic detections coinciding with phases of low photometric flux and strong line emission. These characteristicssupport the theory that a magnetically active, temperature-inverted spot/region is producing an optically thin chromospheric emission region. Comparison with other DAe and DAHe white dwarfsreveals all systems have a strikingly similar antiphase phenomenology, reinforcing the theory that they are subject to a unified physical mechanism. With the detection of a weak magnetic field, we reclassify WD J165335.21−100116.33 as a low-field DAHe white dwarf.

We violate a Bell inequality by performing joint measurements on two copies of the same single-photon entangled state, where one photon acts as a phase reference for the other, making it self-referential. We observe CHSH parameters of 2.71 = 0.09 and 2.23 = 0.07, depending on the joint measurements implemented.

While the membranes of most bacteria and eukaryotes consist of single-headed bilayer lipids, the membranes of archaea are composed of mixtures of single-headed bilayer lipids and double-headed bolalipids. Archaeal bolalipids can adopt straight or u-shaped conformations, enabling them—together with bilayer lipids—to control whether membranes form bilayer or monolayer structures. Yet, the physical principles governing archaeal membranes remain largely unexplored, especially how membrane structure couples to externally imposed curvature during membrane remodeling. Here, we perform coarse-grained molecular dynamics simulations of toroidal vesicles to systematically probe the effects of all relevant combinations of mean and Gaussian curvatures on shape stability and lipid organization. We find that soft bilayer membranes can sustain all curvatures induced, whereas rigid bolalipid monolayer membranes either transition to different vesicle shapes or rupture. Bilayer-mimicking u-shaped bolalipids and bilayer lipids are spatially accumulated in regions of high mean membrane curvature independent of Gaussian curvature. Our work identifies curvature–composition coupling as a physical signature of archaeal membrane remodeling.","lang":"eng"}],"ec_funded":1,"publisher":"AIP Publishing","corr_author":"1","status":"public","oa":1,"month":"04","publication":"Journal of Chemical Physics","quality_controlled":"1","ddc":["540"],"doi":"10.1063/5.0325170","author":[{"orcid":"0000-0001-8501-6017","last_name":"Frey","full_name":"Frey, Felix F","first_name":"Felix F","id":"a0270b37-8f1a-11ec-95c7-8e710c59a4f3"},{"last_name":"Santana de Freitas Amaral","full_name":"Santana de Freitas Amaral, Miguel","first_name":"Miguel","id":"4f2d02dd-47a9-11ec-ad10-82820ed3f501"},{"id":"bf63d406-f056-11eb-b41d-f263a6566d8b","first_name":"Anđela","full_name":"Šarić, Anđela","last_name":"Šarić","orcid":"0000-0002-7854-2139"}],"file":[{"file_id":"21801","file_size":8764791,"content_type":"application/pdf","access_level":"open_access","relation":"main_file","checksum":"2e10c4f4531676e0771ef3730e4b63a9","file_name":"2026_JourChemPhysics_Frey.pdf","creator":"dernst","date_created":"2026-05-05T12:35:24Z","success":1,"date_updated":"2026-05-05T12:35:24Z"}],"oa_version":"Published Version","external_id":{"arxiv":["2603.15170"]},"related_material":{"record":[{"relation":"research_data","status":"public","id":"21800"}]},"arxiv":1,"publication_status":"published","article_number":"144902","issue":"14","PlanS_conform":"1","intvolume":" 164"},{"publication":"Biomacromolecules","month":"04","status":"public","oa":1,"quality_controlled":"1","_id":"21749","OA_place":"repository","date_created":"2026-04-19T22:07:46Z","scopus_import":"1","page":"2956-2965","acknowledgement":"The authors acknowledge Crispin Hetherington and L.

Synthetic peptide assemblies, driven by supramolecular interactions, can form single triple helices through intrahelical amino acid pairs; however, the principles guiding interhelical associations into higher-order structures remain unclear. Here, we incorporate cation−π and electrostatic charge pairs to probe interhelical interactions and elucidate the mechanisms driving triple helix assembly into fibrils, nanotubes, and nanosheets. Introducing cation−π pairs into a fibrillating collagen mimetic resulted in D-periodic fibrils with pH-sensitive gelation. By alternating the presentation of electrostatic and cation−π pairs, the assembly of another D-periodic fibril featuring inner and outer triple-helical layers was resolved by cryo electron microscopy to a resolution of 8 Å. At physiological pH, antiparallel association of these triple helices leads to the formation of nanotubes. The packing behavior of triple helices correlates with the interhelical interactions, where parallel associations favor fibril formation and antiparallel interactions drive nanotube and nanosheet assembly. These self-assembling triple-helical peptides demonstrate how packing of higher-order structures can be tailored with supramolecular interactions and establish the relationship of different hierarchical collagen-mimetic assemblies as pH-dependent."}],"publisher":"American Chemical Society","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","OA_type":"green","article_processing_charge":"No","main_file_link":[{"url":"https://doi.org/10.1101/2025.02.15.637692","open_access":"1"}],"volume":27,"title":"Supramolecular assembly of collagen-mimetic eptide D-periodic fibrils and nanoassemblies","citation":{"ista":"Cole CC, Kreutzberger MAB, Klein K, Cahue KA, Pogostin BH, Farsheed AC, Swain JWR, Bui TH, Dey A, Makhoul JT, Dubackic M, Pal A, Olsson U, Šarić A, Egelman EH, Hartgerink JD. 2026.

Argyrodite-type Ag8SnSe6 exhibits a melt-like Ag sublattice that drives lattice thermal conductivity (κL) below 0.2 watts per meter per kelvin, yet its low carrier concentration limits the power factor. Here, interstitial Ag atoms raise the Fermi level into the conduction band, substantially increasing the electron concentration. Simultaneously, the formation of a secondary Ag2Se phase generates lattice distortions that enhance phonon scattering. A pronounced mismatch between electronic (~200 nanometers) and phononic (~0.22 nanometers) mean free paths decouples charge and heat transport, enabling concurrent suppression of κL and retention of high electrical conductivity. This coupled electronic-phononic modulation yields a record ZT of 0.72 at ambient temperature and a peak ZT of 1.1 at 735 kelvins, with an average ZTavg of 0.72 over 320 to 735 kelvins. A unicouple device achieves 6.3% efficiency under a 357-kelvin gradient, highlighting a practical strategy for high-performance midtemperature thermoelectrics.","lang":"eng"}],"article_type":"original","acknowledgement":"The Scientific Service Units (SSU) of ISTA supported this research through resources provided by the Lab Support Facility (LSF).
