Here, we present a systematic search for broad-line active galactic nuclei (AGNs) in some of the faintest high-z galaxies surveyed yet by combining ultra-deep JWST/NIRSpec G395M spectroscopy with the strong lensing aid in AS1063. By employing the profile of the [O iii]λ5007 emission lines as a template for narrow-line components and carefully cross-validating with mock observations, we identify a sample of 10 broad-line AGNs at 4.5 < z < 7.0 (eight secure, two tentative). The inferred BH masses from the broad Hα line explore the intermediate BH mass regime down to ∼105.5 M⊙. The stellar mass (M*) is estimated with a galaxy+AGN composite model, and we find the BH to stellar mass ratio spans down to MBH/M* ≲ 0.1%, unveiling populations on the empirical MBH–M* relation observed in the local Universe. We also derive the BH mass function and investigate its low-mass end at this epoch. While we confirm the agreement of our results with previous studies at MBH ≳ 106.5M⊙, we find the mass range of ∼105.5 M⊙ features an enhanced abundance with respect to the extrapolated best-fit Schechter function. Comparison with theoretical models suggests that a possible origin for this enhanced abundance is the direct-collapse BH formation, supporting the scenario that the direct collapse of massive gas clouds is a significant pathway for the earliest supermassive BHs.","lang":"eng"}],"date_created":"2026-06-14T22:01:43Z","scopus_import":"1","quality_controlled":"1","author":[{"last_name":"Fei","full_name":"Fei, Qinyue","first_name":"Qinyue"},{"last_name":"Fujimoto","full_name":"Fujimoto, Seiji","first_name":"Seiji"},{"last_name":"Naidu","first_name":"Rohan P.","full_name":"Naidu, Rohan P."},{"last_name":"Chisholm","full_name":"Chisholm, John","first_name":"John"},{"last_name":"Atek","first_name":"Hakim","full_name":"Atek, Hakim"},{"last_name":"Brammer","full_name":"Brammer, Gabriel","first_name":"Gabriel"},{"last_name":"Asada","first_name":"Yoshihisa","full_name":"Asada, Yoshihisa"},{"full_name":"Berg, Danielle A.","first_name":"Danielle A.","last_name":"Berg"},{"last_name":"Bromm","first_name":"Volker","full_name":"Bromm, Volker"},{"full_name":"Furtak, Lukas J.","first_name":"Lukas J.","last_name":"Furtak"},{"last_name":"Greene","full_name":"Greene, Jenny E.","first_name":"Jenny E."},{"full_name":"Hsiao, Tiger Yu Yang","first_name":"Tiger Yu Yang","last_name":"Hsiao"},{"full_name":"Jeon, Junehyoung","first_name":"Junehyoung","last_name":"Jeon"},{"first_name":"Vasily","full_name":"Kokorev, Vasily","last_name":"Kokorev"},{"id":"7439a258-f3c0-11ec-9501-9df22fe06720","first_name":"Jorryt J","full_name":"Matthee, Jorryt J","last_name":"Matthee","orcid":"0000-0003-2871-127X"},{"first_name":"Priyamvada","full_name":"Natarajan, Priyamvada","last_name":"Natarajan"},{"last_name":"Pan","first_name":"Richard","full_name":"Pan, Richard"},{"first_name":"Johan","full_name":"Richard, Johan","last_name":"Richard"},{"last_name":"Saldana-Lopez","first_name":"Alberto","full_name":"Saldana-Lopez, Alberto"},{"last_name":"Schaerer","first_name":"Daniel","full_name":"Schaerer, Daniel"},{"last_name":"Volonteri","first_name":"Marta","full_name":"Volonteri, Marta"},{"first_name":"Adi","full_name":"Zitrin, Adi","last_name":"Zitrin"}],"doi":"10.3847/1538-4357/ae6248","_id":"21999","publication":"The Astrophysical Journal","type":"journal_article","acknowledgement":"We thank the anonymous referee for insightful comments, which significantly improved the manuscript.

However, its conventional implementation quickly becomes intractable on a computer: barycentric subdivision produces poorly shaped simplices, and the star condition introduces many vertices. To address these limitations, this article develops a subdivision scheme based on spherical Delaunay triangulations, which attains better refinement properties than barycentric subdivisions. Moreover, the star condition is reframed as two independent problems, one geometric and the other combinatorial, respectively tackled in the language of locally equiconnected spaces and the list homomorphism problem, allowing an exponential reduction in the number of vertices. Via a prototype implementation, we obtain simplicial complexes homotopy equivalent to Grassmannians and Stiefel manifolds up to dimension 5.","lang":"eng"}],"day":"27","scopus_import":"1","quality_controlled":"1","author":[{"first_name":"Raphaël","full_name":"Tinarrage, Raphaël","id":"40ebcc9d-905f-11ef-bf0a-dc475da8a04e","orcid":"0000-0002-1404-1095","last_name":"Tinarrage"}],"_id":"22000","doi":"10.4230/LIPIcs.SoCG.2026.93","publication":"42nd International Symposium on Computational Geometry","type":"conference","ddc":["500"],"external_id":{"arxiv":["2112.07573"]},"citation":{"mla":"Tinarrage, Raphaël. “Simplicial Approximation to CW Complexes with Spherical Delaunay Triangulations.” <i>42nd International Symposium on Computational Geometry</i>, vol. 367, 93:1-93:22, Schloss Dagstuhl - Leibniz-Zentrum für Informatik, 2026, doi:<a href=\"https://doi.org/10.4230/LIPIcs.SoCG.2026.93\">10.4230/LIPIcs.SoCG.2026.93</a>.","ieee":"R.

However, in three or higher dimensions, there is no known truly subquadratic-time algorithm for any intersection graph of non-trivial objects, even basic ones such as unit balls or (axis-aligned) unit cubes. This was partially explained by the pioneering work of Bringmann et al. [Karl Bringmann et al., 2022] which gave several truly subquadratic lower bounds, notably for unit balls or unit cubes in 3D when the graph diameter Δ is at least Ω(log n), hinting at a pessimistic outlook for the complexity of the diameter problem in higher dimensions. In this paper, we substantially extend the landscape of diameter computation for objects in three and higher dimensions, giving a few positive results. Our highlighted findings include:  \r\n1) A truly subquadratic-time algorithm for deciding if the diameter of unit cubes in 3D is at most 3 (Diameter-3 hereafter), the first algorithm of its kind for objects in 3D or higher dimensions. Our algorithm is based on a novel connection to pseudolines, which is of independent interest. \r\n2) A truly subquadratic time lower bound for Diameter-3 of unit balls in 3D under the Orthogonal Vector (OV) hypothesis, giving the first separation between unit balls and unit cubes in the small diameter regime. Previously, computing the diameter for both objects was known to be quadratic hard when the diameter is Ω(log n) [Karl Bringmann et al., 2022]. \r\n3) A near-linear-time algorithm for Diameter-2 of unit cubes in 3D, generalizing the previous result for unit squares in 2D [Karl Bringmann et al., 2022]. \r\n4) A truly subquadratic-time algorithm and lower bound for Diameter-2 and Diameter-3 of rectangular boxes (of arbitrary dimension and sizes), respectively."}],"day":"27","date_created":"2026-06-14T22:01:44Z","file_date_updated":"2026-06-22T08:34:11Z","keyword":["Graph Diameter","Geometric Intersection Graphs","Unit Ball Graphs"],"volume":367,"title":"Charting the diameter computation landscape of intersection graphs in 3D and above","language":[{"iso":"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"},"OA_type":"gold","alternative_title":["LIPIcs"],"file":[{"file_id":"22114","file_name":"2026_LIPIcSSoCG_Chan.pdf","date_created":"2026-06-22T08:34:11Z","relation":"main_file","date_updated":"2026-06-22T08:34:11Z","creator":"dernst","checksum":"ffff03934cc182757d6db82d88f896e6","file_size":918197,"access_level":"open_access","content_type":"application/pdf","success":1}],"oa_version":"Published Version","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","OA_place":"publisher","publication_identifier":{"isbn":["9783959774185"],"eissn":["1868-8969"]},"has_accepted_license":"1","corr_author":"1","year":"2026","status":"public","das_tickbox":"0","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","month":"05","date_published":"2026-05-27T00:00:00Z","publication_status":"published","date_updated":"2026-06-22T08:37:44Z","article_number":"29:1-29:15","department":[{"_id":"MoHe"}],"conference":{"location":"New Brunswick, NJ, United States","end_date":"2026-06-05","name":"SoCG: Symposium on Computational Geometry","start_date":"2026-06-02"},"article_processing_charge":"Yes","oa":1},{"scopus_import":"1","language":[{"iso":"eng"}],"title":"Quantitative monitoring of Signal First-Order logic","volume":16557,"keyword":["Signal first-order logic","Robustness-based quantitative semantics","Online runtime monitoring"],"file_date_updated":"2026-06-22T08:18:41Z","date_created":"2026-06-14T22:01:44Z","day":"18","abstract":[{"text":"Runtime monitoring checks, during execution, whether a partial signal produced by a hybrid system satisfies its specification.

We provide the first robustness-based quantitative semantics for SFO, enabling the expression and evaluation of rich real-time properties beyond the scope of existing formalisms such as Signal Temporal Logic. To enable online monitoring, we identify a past-time fragment of SFO and give a pastification procedure that transforms bounded-response SFO formulas into equisatisfiable formulas in this fragment. We then develop an efficient runtime monitoring algorithm for this past-time fragment and evaluate its performance on a set of benchmarks, demonstrating the practicality and effectiveness of our approach. To the best of our knowledge, this is the first publicly available prototype for online quantitative monitoring of full SFO.","lang":"eng"}],"publication":"27th International Symposium on Formal Methods","type":"conference","external_id":{"arxiv":["2603.00728"]},"ddc":["000"],"citation":{"ama":"Chalupa M, Henzinger TA, Sarac NE, Yu E.

Combining them with strong, long-range dipolar interactions provides highly flexible control schemes promising even more exotic quantum phases. Recently, microwave shielding gave access to spin-polarized degenerate samples of dipolar fermionic molecules, where tunable p-wave interactions were enabled by field-linked resonances available only by compromising the shielding (due to experimental limitations). Here, we study the scattering properties of a fermionic dipolar spin mixture and show that a universal s-wave resonance is readily accessible without compromising the shielding. We develop a universal description of the tunable s-wave interaction and weakly bound tetratomic states based on the microwave-field parameters. The s-wave resonance paves the way to stable, controllable and strongly-interacting dipolar spin mixtures of deeply degenerate fermions and supports favorable conditions to reach this regime via evaporative cooling."}],"date_created":"2026-06-21T22:02:58Z","title":"Tunable field-linked s-wave interactions in dipolar fermi mixtures","DOAJ_listed":"1","language":[{"iso":"eng"}],"file_date_updated":"2026-06-24T06:09:35Z","volume":9,"scopus_import":"1","doi":"10.1038/s42005-026-02578-8","_id":"22100","project":[{"_id":"7c040762-9f16-11ee-852c-dd79eeee4ab3","name":"Coherent Optical Metrology Beyond Electric-Dipole-Allowed Transitions","grant_number":"F100403"},{"_id":"8fa7db46-16d5-11f0-9cad-917600954daf","name":"Polarons in Lead Halide Perovskites","grant_number":"12078"}],"quality_controlled":"1","author":[{"last_name":"Li","id":"ff19510a-0d2c-11ef-b018-c338ad2f4325","full_name":"Li, Jinglun","first_name":"Jinglun"},{"full_name":"Koutentakis, Georgios","first_name":"Georgios","id":"d7b23d3a-9e21-11ec-b482-f76739596b95","last_name":"Koutentakis"},{"last_name":"Hrast","first_name":"Mateja","full_name":"Hrast, Mateja","id":"48dbb294-2a9c-11ef-905d-f56be71f0e5d"},{"last_name":"Lemeshko","orcid":"0000-0002-6990-7802","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","full_name":"Lemeshko, Mikhail"},{"last_name":"Schindewolf","full_name":"Schindewolf, Andreas","first_name":"Andreas"},{"first_name":"Ragheed","full_name":"Al Hyder, Ragheed","id":"d1c405be-ae15-11ed-8510-ccf53278162e","last_name":"Al Hyder"}],"acknowledgement":"J.-L.Li thanks Gaoren Wang for valuable discussions on the absorbing boundary condition.

However, reasoning about DP is a challenging and error-prone task, hence methods for formal verification and refutation of DP properties have received significant interest in recent years. In this work, we present a novel method for automated formal refutation of є-DP. Our method refutes є-DP by searching for a pair of inputs together with a non-negative function over outputs whose expected value on these two inputs differs by a significant amount. The two inputs and the non-negative function over outputs are computed simultaneously, by utilizing upper expectation supermartingales and lower expectation submartingales from probabilistic program analysis, which we leverage to introduce a sound and complete proof rule for є-DP refutation. To the best of our knowledge, our method is the first method for є-DP refutation to offer the following four desirable features: (1) it is fully automated, (2) it is applicable to stochastic mechanisms with sampling instructions from both discrete and continuous distributions, (3) it provides soundness guarantees, and (4) it provides semi-completeness guarantees. Our experiments show that our prototype tool SuperDP achieves superior performance compared to the state of the art and manages to refute є-DP for a number of challenging examples collected from the literature, including ones that were out of the reach of prior methods.","lang":"eng"}],"volume":10,"keyword":["Static Program Analysis","Differential Privacy","Probabilistic Programming","Martingales"],"file_date_updated":"2026-06-24T06:19:56Z","language":[{"iso":"eng"}],"related_material":{"record":[{"id":"22134","relation":"research_data","status":"public"}]},"title":"SuperDP: Differential privacy refutation via supermartingales","scopus_import":"1","project":[{"name":"Formal Methods for Stochastic Models: Algorithms and Applications","grant_number":"863818","call_identifier":"H2020","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E"}],"_id":"22102","doi":"10.1145/3808296","author":[{"orcid":"0000-0002-4561-241X","last_name":"Chatterjee","full_name":"Chatterjee, Krishnendu","first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Ehsan","full_name":"Kafshdar Goharshadi, Ehsan","id":"103b4fa0-896a-11ed-bdf8-87b697bef40d","orcid":"0000-0002-8595-0587","last_name":"Kafshdar Goharshadi"},{"id":"294AA7A6-F248-11E8-B48F-1D18A9856A87","first_name":"Dorde","full_name":"Zikelic, Dorde","last_name":"Zikelic","orcid":"0000-0002-4681-1699"}],"quality_controlled":"1","intvolume":"        10","arxiv":1,"ddc":["000"],"external_id":{"arxiv":["2603.26215"]},"acknowledgement":"The authors would like to thank Petr Novotný for valuable discussions that helped shape this work.\r\nThis research was supported by the Singapore Ministry of Education (MOE) Academic Research\r\nFund (AcRF) Tier 1 grant (Proposal ID: 25-SIS-SMU-009), Vienna Science and Technology Fund\r\n(WWTF), State of Lower Austria [Grant ID 10.47379/ICT25017], ERC CoG 863818 (ForM-SMArt),\r\nand Austrian Science Fund (FWF) 10.55776/COE12.","citation":{"ista":"Chatterjee K, Goharshady E, Zikelic D. 2026.

Diptera have undergone multiple sex-chromosome turnovers and expansions while maintaining their general chromosomal content, which makes them an ideal clade to study such transitions. We analysed more than 100 dipteran whole-genome assemblies and identified 4 new lineages that underwent sex-chromosome turnover (in addition to the 5 previously reported). We find the majority of turnovers happened in the group Schizophora, which tend to have fewer genes on the F element (the chromosome homologous to the ancestral insect X chromosome) than lower dipterans, a factor previously hypothesized to facilitate turnover. Most derived X chromosomes have higher GC content than autosomes, consistent with a high prevalence of male-achiasmy in Diptera. In addition, an excess of gene movement out of the X is detected for most of these new X chromosomes, and many of these moved genes have high testis expression in Drosophila, suggesting that out-of-X gene movement contributes to the long-term demasculinization of X chromosomes.","lang":"eng"}],"article_processing_charge":"No","day":"8","type":"research_data","user_id":"68b8ca59-c5b3-11ee-8790-cd641c68093d","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_version":"Published Version","file":[{"date_updated":"2025-12-17T10:09:25Z","access_level":"open_access","file_size":1201,"checksum":"0b79be6229f2ad9ac117ef00fc4f5c0e","content_type":"text/plain","creator":"llayanaf","success":1,"file_id":"20834","date_created":"2025-12-17T10:09:25Z","file_name":"README.txt","relation":"main_file"},{"date_created":"2025-12-17T10:10:11Z","file_name":"Supplementary_Datasets.zip","relation":"main_file","file_id":"20835","access_level":"open_access","file_size":19052849,"content_type":"application/zip","checksum":"daf1c03149dd170b14e5c8e109ee3c77","creator":"llayanaf","success":1,"date_updated":"2025-12-17T10:10:11Z"},{"date_updated":"2025-12-17T10:12:05Z","success":1,"content_type":"application/zip","access_level":"open_access","file_size":4575,"checksum":"251e7aab01917c2ad2fbccf465492ea1","creator":"llayanaf","file_id":"20837","relation":"main_file","date_created":"2025-12-17T10:12:05Z","file_name":"Perl_scripts.zip"},{"creator":"llayanaf","checksum":"3cabf143b8cd286eae48c598da2b03bd","access_level":"open_access","file_size":572362,"content_type":"application/zip","success":1,"date_updated":"2026-01-08T01:35:08Z","file_name":"Supplementary_Tables.zip","date_created":"2026-01-08T01:35:08Z","relation":"main_file","file_id":"20959"}],"citation":{"ista":"Layana Franco LA, Toups MA, Vicoso B. 2026.

Here, after refining a figure-of-merit for the problem, we present a 1-milligram torsional pendulum operating at 18 Hz. We demonstrate laser cooling its motion from room temperature to 240 microkelvins, surpassing by over 20-fold the coldest motions attained for oscillators ranging from micrograms to kilograms. We quantify and contrast the utility of the current approach with other platforms. The achieved performance and large improvement potential highlight milligram-scale torsional pendulums as a powerful platform for precision measurements relevant to future studies at the quantum-gravity interface."}],"day":"04","date_created":"2025-12-21T11:39:04Z","file_date_updated":"2026-03-16T10:07:46Z","volume":9,"DOAJ_listed":"1","title":"One-milligram torsional pendulum toward experiments at the quantum-gravity interface","related_material":{"record":[{"id":"20842","relation":"research_data","status":"public"}]},"language":[{"iso":"eng"}],"scopus_import":"1","project":[{"_id":"bdb2a702-d553-11ed-ba76-f12e3e5a3bc6","name":"A quantum hybrid of atoms and milligram-scale pendulums: towards gravitational quantum mechanics","grant_number":"101087907"}],"doi":"10.1038/s42005-026-02514-w","_id":"20840","author":[{"full_name":"Agafonova, Sofya","first_name":"Sofya","id":"09501ff6-dca7-11ea-a8ae-b3e0b9166e80","orcid":"0000-0003-0582-2946","last_name":"Agafonova"},{"last_name":"Rosello","full_name":"Rosello, Pere","first_name":"Pere"},{"full_name":"Mekonnen, Manuel","first_name":"Manuel","last_name":"Mekonnen"},{"id":"4C02D85E-F248-11E8-B48F-1D18A9856A87","first_name":"Onur","full_name":"Hosten, Onur","last_name":"Hosten","orcid":"0000-0002-2031-204X"}],"quality_controlled":"1","arxiv":1,"intvolume":"         9","citation":{"ista":"Agafonova S, Rosello P, Mekonnen M, Hosten O. 2026.

As their depletion suppresses translation and, consequently, viral replication, tRNAs represent long-standing and increasingly recognized targets of innate immunity1,2,3,4,5. Here we report Cas12a3 effector nucleases from type V CRISPR–Cas adaptive immune systems in bacteria that preferentially cleave tRNAs after recognition of target RNA. Cas12a3 orthologues belong to one of two previously unreported nuclease clades that exhibit RNA-mediated cleavage of non-target RNA, and are distinct from all other known type V systems. Through cell-based and biochemical assays and direct RNA sequencing, we demonstrate that recognition of a complementary target RNA by the CRISPR RNA triggers Cas12a3 to cleave the conserved 5′-CCA-3′ tail of diverse tRNAs to drive growth arrest and anti-phage defence. Cryogenic electron microscopy structures further revealed a distinct tRNA-loading domain that positions the tRNA tail in the RuvC active site of the nuclease. By designing synthetic reporters that mimic the tRNA acceptor stem and tail, we expanded the capacity of current CRISPR-based diagnostics for multiplexed RNA detection. Overall, these findings reveal widespread tRNA inactivation as a previously unrecognized CRISPR-based immune strategy that broadens the application space of the existing CRISPR toolbox.","lang":"eng"}],"day":"07","main_file_link":[{"url":"https://doi.org/10.1038/s41586-025-09852-9","open_access":"1"}],"language":[{"iso":"eng"}],"title":"RNA-triggered Cas12a3 cleaves tRNA tails to execute bacterial immunity","ddc":["570"],"external_id":{"pmid":["41501459"]},"acknowledgement":"We thank Ł. Koziej for processing of the initial cryo-EM datasets, S. Schmelz for support in cryo-EM, A. Gatzemeier for assistance in the purification of dBa1Cas12a3, R. Rarose for support with the in vitro RNA experiments, M. Kaminski for providing purified PsmCas13b protein, L. Schönemann for protein purification, and C. Krempl and S. Backesfor providing the RSV and influenza A transcript-encoding plasmids.

However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large-scale atmospheric circulation. Observing this functional coupling in nature is challenging because the key processes occur over a wide range of spatial and temporal scales. However, recent advances in observational techniques and modeling have provided new insights into these interactions. In this review, we summarize the current state of knowledge on glacier-atmosphere interactions in high-mountain regions at different scales, and highlight recent advances in observational and numerical modeling. We also highlight important knowledge gaps and outline future research directions to improve the prediction of glacier change in a warming world.","lang":"eng"}],"publication_identifier":{"eissn":["1944-9208"],"issn":["8755-1209"]},"OA_place":"publisher","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"Published Version","OA_type":"hybrid","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"},"issue":"1","year":"2026","status":"public","has_accepted_license":"1","publication_status":"epub_ahead","date_updated":"2026-01-12T10:04:17Z","date_published":"2026-01-05T00:00:00Z","article_type":"original","month":"01","PlanS_conform":"1","ec_funded":1,"oa":1,"article_processing_charge":"Yes (in subscription journal)","article_number":"e2024RG000869","department":[{"_id":"FrPe"}]},{"publication":"Current Biology","type":"journal_article","intvolume":"        36","external_id":{"pmid":["41494523"]},"citation":{"ista":"Kücükdereli H, Douglass AM. 2026.

A new parametrization has demonstrated that the damping wing signature also carries local information about the distribution of neutral hydrogen (H I) in front of the quasar before it started shining. Leveraging a recently introduced Bayesian JAX-based Hamiltonian Monte Carlo inference framework, we derive constraints on the Lorentzian-weighted H I column density NDW H I , the quasar’s distance rpatch to the first neutral patch, and its lifetime tQ based on James Webb Space\r\nTelescope (JWST) Near Infrared Spectrograph (NIRSpec) spectra of the two z ∼ 7.5 quasars J1007+2115 and J1342+0928. After folding in model-dependent topology information, we find that J1007+2115 (and J1342+0928) is most likely to reside in a (xH1)= 0.32+0.22 −0.20 (0.58+0.23 −0.23) neutral IGM while shining for a remarkably short lifetime of log10 tQ/yr = 4.14+0.74 −0.18 (an intermediate lifetime of 5.64+0.25 −0.43) along a sightline with log10 NDW\r\nH I /cm−2 = 19.70+0.35 −0.86 (20.24+0.25 −0.22) and rpatch = 28.9+54.0 −14.4 cMpc\r\n(10.9+5.6−5.9 cMpc). In light of the potential presence of local absorbers in the foreground of J1342+0928 as has been recently suggested, we also demonstrate how the Lorentzian-weighted column density NDW H I provides a natural means for quantifying their contribution to the observed damping wing signal."}],"date_created":"2026-01-11T23:01:34Z","file_date_updated":"2026-01-12T09:43:07Z","volume":545,"DOAJ_listed":"1","title":"First constraints on the local ionization topology in front of two quasars at z ∼ 7.5","language":[{"iso":"eng"}],"scopus_import":"1"},{"doi":"10.1038/s41550-025-02745-x","_id":"20975","quality_controlled":"1","status":"public","author":[{"last_name":"Heintz","first_name":"Kasper E.","full_name":"Heintz, Kasper E."},{"last_name":"Bennett","full_name":"Bennett, Jake S.","first_name":"Jake S."},{"last_name":"Oesch","full_name":"Oesch, Pascal A.","first_name":"Pascal A."},{"first_name":"Albert","full_name":"Sneppen, Albert","last_name":"Sneppen"},{"full_name":"Rennehan, Douglas","first_name":"Douglas","last_name":"Rennehan"},{"full_name":"Pollock, Clara L.","first_name":"Clara L.","last_name":"Pollock"},{"last_name":"Witstok","first_name":"Joris","full_name":"Witstok, Joris"},{"last_name":"Smit","first_name":"Renske","full_name":"Smit, Renske"},{"last_name":"Vejlgaard","first_name":"Simone","full_name":"Vejlgaard, Simone"},{"last_name":"Terp","first_name":"Chamilla","full_name":"Terp, Chamilla"},{"last_name":"Koca","first_name":"Umran S.","full_name":"Koca, Umran S."},{"full_name":"Brammer, Gabriel B.","first_name":"Gabriel B.","last_name":"Brammer"},{"full_name":"Finlator, Kristian","first_name":"Kristian","last_name":"Finlator"},{"full_name":"Hayes, Matthew J.","first_name":"Matthew J.","last_name":"Hayes"},{"first_name":"Debora","full_name":"Sijacki, Debora","last_name":"Sijacki"},{"first_name":"Rohan P.","full_name":"Naidu, Rohan P.","last_name":"Naidu"},{"id":"7439a258-f3c0-11ec-9501-9df22fe06720","full_name":"Matthee, Jorryt J","first_name":"Jorryt J","last_name":"Matthee","orcid":"0000-0003-2871-127X"},{"last_name":"Valentino","first_name":"Francesco","full_name":"Valentino, Francesco"},{"last_name":"Tanvir","first_name":"Nial R.","full_name":"Tanvir, Nial R."},{"last_name":"Jakobsson","full_name":"Jakobsson, Páll","first_name":"Páll"},{"first_name":"Peter","full_name":"Laursen, Peter","last_name":"Laursen"},{"last_name":"Watson","full_name":"Watson, Darach J.","first_name":"Darach J."},{"last_name":"Davé","first_name":"Romeel","full_name":"Davé, Romeel"},{"last_name":"Keating","full_name":"Keating, Laura C.","first_name":"Laura C."},{"last_name":"Covelo-Paz","full_name":"Covelo-Paz, Alba","first_name":"Alba"}],"year":"2026","citation":{"ista":"Heintz KE, Bennett JS, Oesch PA, Sneppen A, Rennehan D, Pollock CL, Witstok J, Smit R, Vejlgaard S, Terp C, Koca US, Brammer GB, Finlator K, Hayes MJ, Sijacki D, Naidu RP, Matthee JJ, Valentino F, Tanvir NR, Jakobsson P, Laursen P, Watson DJ, Davé R, Keating LC, Covelo-Paz A. 2026.

They emerged through hierarchical structure formation of large-scale dark matter and baryon overdensities. Early galaxy ‘proto-clusters’ are believed to have substantially contributed to the cosmic star-formation rate density and served as ‘hotspots’ for the reionization of the intergalactic medium. Our understanding of the formation of these structures at the earliest cosmic epochs is, however, limited to sparse observations of their galaxy members or is based on phenomenological models and cosmological simulations. Here we report the detection of a large and coherent structure of neutral atomic hydrogen gas (H i) extending from a galaxy proto-cluster at redshift z = 5.4, one billion years after the Big Bang. The presence of this H i gas is revealed by strong damped Lyman-α absorption features observed in several background-galaxy spectra. Although the sight lines overall probe a large range in H i column densities, NHI = 1020 cm−2 to 1023.5 cm−2, they are similar across nearby sight lines, demonstrating that they probe the same dense neutral gas. This observation of a dense large-scale overdensity of cold neutral gas challenges current cosmological simulations and has strong implications for the reionization topology of the Universe."}],"day":"02","article_processing_charge":"No","date_created":"2026-01-11T23:01:34Z","department":[{"_id":"JoMa"}],"title":"A dense web of neutral gas in a galaxy proto-cluster post-reionization","language":[{"iso":"eng"}],"publisher":"Springer Nature","month":"01","article_type":"original","date_published":"2026-01-02T00:00:00Z","scopus_import":"1","publication_status":"epub_ahead","date_updated":"2026-01-12T09:53:21Z"},{"ec_funded":1,"publisher":"Society for Industrial & Applied Mathematics","date_updated":"2026-01-20T07:40:39Z","publication_status":"published","month":"01","date_published":"2026-01-01T00:00:00Z","article_type":"original","department":[{"_id":"HeEd"}],"article_processing_charge":"No","oa":1,"OA_type":"green","oa_version":"Preprint","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_identifier":{"issn":["1536-0040"]},"OA_place":"repository","status":"public","year":"2026","issue":"1","scopus_import":"1","date_created":"2026-01-12T11:17:06Z","day":"01","abstract":[{"lang":"eng","text":"Morse decompositions partition the flows in a vector field into equivalent structures. Given such a decomposition, one can define a further summary of its flow structure by what is called a connection matrix. These matrices, a generalization of Morse boundary operators from classical Morse theory, capture the connections made by the flows among the critical structures—such as attractors, repellers, and orbits—in a vector field. Recently, in the context of combinatorial dynamics, an efficient persistence-like algorithm to compute connection matrices has been proposed in Dey, Lipiński, Mrozek, and Slechta [SIAM J. Appl. Dyn. Syst., 23 (2024), pp. 81–97]. We show that, actually, the classical persistence algorithm with exhaustive reduction retrieves connection matrices, both simplifying the algorithm of Dey et al. and bringing the theory of persistence closer to combinatorial dynamical systems. We supplement this main result with an observation: the concept of persistence as defined for scalar fields naturally adapts to Morse decompositions whose Morse sets are filtered with a Lyapunov function. We conclude by presenting preliminary experimental results."}],"volume":25,"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2502.19369","open_access":"1"}],"language":[{"iso":"eng"}],"title":"Computing a connection matrix and persistence efficiently from a morse decomposition","intvolume":"        25","arxiv":1,"ddc":["510"],"external_id":{"arxiv":["2502.19369"]},"citation":{"short":"T.K.
