The ability of the linker to position the foldamer helix and the duplex DNA so that their rims and grooves are in register, despite their completely different chemical nature, was demonstrated using single crystal X‐ray diffraction, circular dichroism and molecular models. Bio‐layer interferometry confirmed that artificial hairpin DNA duplexes keep their ability to bind to DNA binding proteins.

Herein, we report a ligand-free aqueous synthesis of Te-doped CuAgSe (CuAgSe1-xTex), where structural and electronic modulation improve carrier transport and suppress phonon propagation. Ex-situ time-resolved X-ray diffraction reveals a spontaneous growth mechanism, while density functional theory calculations show that Te-5s and 5p orbitals hybridization generates localized states and an asymmetric density of states, thereby enhancing the Seebeck coefficient. Electron microscopy and strain analyses confirm that Te-doping introduces a high density of lattice dislocations and grain boundaries, leading to a reduced lattice thermal conductivity of 0.11 W m−1K−1 at 443 K. These synergistic effects translate into device-level performance—the first integrated CuAgSe thermoelectric modules, exhibit a maximum cooling temperature difference of 27.3 K, and power density of 0.34 W cm−2 with a conversion efficiency of 3.6% at a modest temperature gradient of 136 K. These results demonstrate that CuAgSe1-xTex enables efficient energy harvesting and localized cooling under small temperature gradient, underscoring the importance of structural and electronic design beyond conventional zT benchmarks.","lang":"eng"}],"date_created":"2026-01-11T23:01:34Z","quality_controlled":"1","title":"Efficient near room temperature thermoelectric cooling and power generation with CuAgSe","article_type":"original","publication":"Small","pmid":1,"_id":"20973","publisher":"Wiley","day":"30"},{"publication_status":"published","doi":"10.1063/5.0290636","type":"journal_article","oa_version":"Preprint","status":"public","date_updated":"2026-01-12T09:57:53Z","department":[{"_id":"JoFi"}],"article_processing_charge":"No","author":[{"first_name":"Lipi","last_name":"Patel","full_name":"Patel, Lipi"},{"first_name":"Samarth","orcid":"0000-0002-1965-4309","id":"221708e1-1ff6-11ee-9fa6-85146607433e","full_name":"Hawaldar, Samarth","last_name":"Hawaldar"},{"first_name":"Aditya","last_name":"Panikkar","full_name":"Panikkar, Aditya"},{"first_name":"Athreya","last_name":"Shankar","full_name":"Shankar, Athreya"},{"full_name":"Suri, Baladitya","last_name":"Suri","first_name":"Baladitya"}],"scopus_import":"1","citation":{"ama":"Patel L, Hawaldar S, Panikkar A, Shankar A, Suri B.

We observe amplification with 18 dB gain over a wide 400 MHz bandwidth centered around 5.3 GHz with added noise approaching the quantum limit, and a saturation power of −114 dBm. To accurately explain our experimental results, we extend existing theories for IEJPAs to incorporate the full sine nonlinearity of both the JPA and the transformer.

Despite extensive characterization in rodents, their detection in humans is limited by coarse spatial sampling, interictal epileptiform discharges (IEDs), and a lack of consensus on human ripple localization and morphology. Here, we demonstrate that mouse and human hippocampal ripples share spatial, spectral and temporal features, which are clearly distinct from IEDs. In recordings from male APP/PS1 mice, SPW-Rs were distinguishable from IEDs by multiple criteria. Hippocampal ripples recorded during NREM sleep in female and male surgical epilepsy patients exhibited similar narrowband frequency peaks and multiple ripple cycles in the CA1 and subiculum regions. Conversely, IEDs showed a broad spatial extent and wide-band frequency power. We developed a semi-automated, ripple curation toolbox (ripmap) to separate event waveforms by low-dimensional embedding to reduce false-positive rate in selected ripple channels. Our approach improves ripple detection and provides a firm foundation for future human memory research."}],"date_created":"2026-01-11T23:01:35Z","intvolume":"        16","quality_controlled":"1"},{"date_updated":"2026-01-20T07:23:34Z","department":[{"_id":"BiCh"}],"article_processing_charge":"Yes","author":[{"full_name":"Zhong, Peichen","last_name":"Zhong","first_name":"Peichen"},{"first_name":"Dongjin","full_name":"Kim, Dongjin","last_name":"Kim"},{"full_name":"King, Daniel S.","last_name":"King","first_name":"Daniel S."},{"orcid":"0000-0002-3584-9632","id":"cbe3cda4-d82c-11eb-8dc7-8ff94289fcc9","first_name":"Bingqing","full_name":"Cheng, Bingqing","last_name":"Cheng"}],"publication_status":"published","doi":"10.1038/s41524-025-01911-z","type":"journal_article","oa_version":"Published Version","status":"public","acknowledgement":"The authors thank for valuable discussions with Pinchen Xie, David Limmer, Jeff Neaton, and Greg Voth.

Machine learning interatomic potentials (MLIPs) offer an efficient and scalable alternative to quantum mechanical methods, but do not by themselves incorporate electrical response. Here, we show that polarization and Born effective charge (BEC) tensors can be directly extracted from long-range MLIPs within the Latent Ewald Summation (LES) framework, solely by learning from energy and force data. Using this approach, we predict the infrared spectra of bulk water under zero or finite external electric fields, ionic conductivities of high-pressure superionic ice, and the phase transition and hysteresis in ferroelectric PbTiO3 perovskite. This work thus extends the capability of MLIPs to predict electrical response –without training on charges or polarization or BECs– and enables accurate modeling of electric-field-driven processes in diverse systems at scale."}],"intvolume":"        11","quality_controlled":"1","PlanS_conform":"1","publication":"npj Computational Materials","volume":11,"OA_place":"publisher","article_type":"original","title":"Machine learning interatomic potential can infer electrical response","_id":"20990","publisher":"Springer Nature","day":"29","ddc":["540"]},{"publication_identifier":{"eissn":["2397-3129"]},"external_id":{"arxiv":["2408.11453"]},"OA_type":"diamond","file":[{"checksum":"3d38e850b40f3e1abbfd30073bd4388a","relation":"main_file","file_size":393625,"file_name":"2025_DiscreteAnalysis_Browning.pdf","date_updated":"2026-02-12T07:50:47Z","content_type":"application/pdf","creator":"dernst","file_id":"21214","date_created":"2026-02-12T07:50:47Z","access_level":"open_access","success":1}],"acknowledgement":"Supported by FWF grant (DOI 10.55776/P36278), Supported by European Union’s Horizon 2020 research and innovation program under the Marie Skłodowska-Curie Grant\r\nAgreement No. 101034413.","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"09","file_date_updated":"2026-02-12T07:50:47Z","project":[{"name":"Rational curves via function field analytic number theory","_id":"bd8a4fdc-d553-11ed-ba76-80a0167441a3","grant_number":"P36278"},{"name":"IST-BRIDGE: International postdoctoral program","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","call_identifier":"H2020","grant_number":"101034413"}],"corr_author":"1","scopus_import":"1","language":[{"iso":"eng"}],"article_number":"12","has_accepted_license":"1","citation":{"mla":"Browning, Timothy D., and Matteo Verzobio. “Counting Integer Points on Affine Surfaces with a Side Condition.” <i>Discrete Analysis</i>, vol. 2025, 12, Cambridge: Alliance of Diamond Open Access Journals, 2025, doi:<a href=\"https://doi.org/10.19086/da.143787\">10.19086/da.143787</a>.","ieee":"T.

It works by solving the SDP relaxation of [Arora-Rao-Vazirani, STOC 2004] using the Multiplicative Weights Update algorithm (MW) of [Arora-Kale, JACM 2016]. To implement one MW step, Sherman approximately solves a multicommodity flow problem using another application of MW. Nested MW steps are solved via a certain \"chaining\" algorithm that combines results of multiple calls to the maxflow algorithm. We present an alternative approach that avoids solving the multicommodity flow problem and instead computes \"violating paths\". This simplifies Sherman's algorithm by removing a need for a nested application of MW, and also allows parallelization: we show how to compute O(√(log n)/ε)-approximation via O(logO(1) n) maxflows using O(nε) processors. We also revisit Sherman's chaining algorithm, and present a simpler version together with a new analysis.","lang":"eng"}],"date_created":"2026-01-20T10:04:02Z"},{"author":[{"last_name":"Bleile","full_name":"Bleile, Yossi","id":"920a7385-7995-11ef-9bfd-8c434cd8f3c2","orcid":"0000-0002-4861-9174","first_name":"Yossi"},{"last_name":"Fajstrup","full_name":"Fajstrup, Lisbeth","first_name":"Lisbeth"},{"orcid":"0000-0002-1780-2689","id":"4879BB4E-F248-11E8-B48F-1D18A9856A87","first_name":"Teresa","full_name":"Heiss, Teresa","last_name":"Heiss"},{"first_name":"Anne Marie","last_name":"Svane","full_name":"Svane, Anne Marie"},{"last_name":"Sørensen","full_name":"Sørensen, Søren Strandskov","first_name":"Søren Strandskov"}],"article_processing_charge":"No","oa":1,"date_published":"2025-05-23T00:00:00Z","date_updated":"2026-01-21T10:34:57Z","year":"2025","department":[{"_id":"HeEd"}],"status":"public","publication_status":"submitted","date_created":"2026-01-20T10:12:21Z","abstract":[{"lang":"eng","text":"Motivated by applications in chemistry, we give a homlogical definition of tunnels, or more generally cobordisms, connecting disjoint parts of a cell complex.

Unfortunately, the BFT consensus algorithms that are the backbone of most of these blockchains scale poorly and offer limited throughput. In fact, many state-of-the-art BFT consensus algorithms require a single leader process to receive and validate votes from a quorum of processes and then broadcast the result, which is inherently non-scalable. Recent approaches avoid this bottleneck by using dissemination/aggregation trees to propagate values and collect and validate votes. However, the use of trees increases the round latency, which limits the throughput for deeper trees. In this paper we propose Kauri, a BFT communication abstraction that sustains high throughput as the system size grows by leveraging a novel pipelining technique to perform scalable dissemination and aggregation on trees. Furthermore, when the number of faults is moderate (arguably the most common case in practice), our construction is able to recover from faults in an optimal number of reconfiguration steps. We implemented and experimentally evaluated Kauri with up to 800 processes. Our results show that Kauri outperforms the throughput of state-of-the-art permissioned blockchain protocols, by up to 58x without compromising latency. Interestingly, in some cases, the parallelization provided by Kauri can also decrease the latency.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1145/3769423"}],"quality_controlled":"1"},{"month":"01","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","conference":{"name":"ICLR: International Conference on Learning Representations","location":"Singapore","start_date":"2025-04-24","end_date":"2025-04-28"},"file":[{"file_size":24386863,"relation":"main_file","checksum":"6c8dfe4291c41d5a2c2fd838105e10b9","file_name":"2025_ICLR_Gairola.pdf","date_updated":"2026-02-09T06:06:14Z","content_type":"application/pdf","creator":"dernst","access_level":"open_access","success":1,"date_created":"2026-02-09T06:06:14Z","file_id":"21162"}],"related_material":{"link":[{"url":"https://github.com/sidgairo18/how-to-probe","relation":"software"}]},"acknowledgement":"We sincerely thank Sukrut Rao and Yue Fan for their valuable feedback on the paper and insightful discussions throughout the project.

Contrarily, in this work we bring forward empirical evidence that challenges this very notion. Surprisingly, we discover a strong dependency on and demonstrate that the training details of a pre-trained model’s classification layer (<10% of model parameters) play a crucial role, much more than the pre-training scheme itself. This is of high practical relevance: (1) as techniques for pre-training models are becoming increasingly diverse, understanding the interplay between these techniques and attribution methods is critical; (2) it sheds light on an important yet overlooked assumption of post-hoc attribution methods which can drastically impact model explanations and how they are interpreted eventually. With this finding we also present simple yet effective adjustments to the classification layers, that can significantly enhance the quality of model explanations. We validate our findings across several visual pre-training frameworks (fully-supervised, self-supervised, contrastive vision-language training) and analyse how they impact explanations for a wide range of attribution methods on a diverse set of evaluation metrics."}],"quality_controlled":"1"},{"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"oa":1,"date_published":"2025-01-09T00:00:00Z","year":"2025","issue":"POPL","abstract":[{"lang":"eng","text":"Program logics have proven a successful strategy for verification of complex programs.

It is a frustrating fact of the status quo that whoever defines a new program logic must establish every part, both semantics and proof rules, from scratch. In spite of programming languages and program logics typically sharing many core features, reuse is generally not available across languages. Even inside one language, if the same underlying operation appears in multiple language primitives, reuse is typically not possible when establishing proof rules for the program logic.\r\nTo enable reuse across and inside languages when defining complex program logics (and proving them sound), we serve program logics à la carte by combining program logic fragments for the various effects of the language. Among other language features, the menu includes shared state, concurrency, and non-determinism as reusable, composable blocks that can be combined to define a program logic modularly.

The resulting IVL program is then verified using an existing back-end verifier. A soundness proof for such a translational verifier needs to relate the input program and verification logic to the semantics of the IVL, which in turn needs to be connected with the verification logic implemented in the back-end verifiers. Performing such proofs is challenging due to the large semantic gap between the input and output programs and logics, especially for complex verification logics such as separation logic.\r\nThis paper presents a formal framework for reasoning about translational separation logic verifiers. At its center is a generic core IVL that captures the essence of different separation logics. We define its operational semantics and formally connect it to two different back-end verifiers, which use symbolic execution and verification condition generation, resp. Crucially, this semantics uses angelic non-determinism to enable the application of different proof search algorithms and heuristics in the back-end verifiers. An axiomatic semantics for the core IVL simplifies reasoning about the front-end translation by performing essential proof steps once and for all in the equivalence proof with the operational semantics rather than for each concrete front-end translation.\r\nWe illustrate the usefulness of our formal framework by instantiating our core IVL with elements of Viper and connecting it to two Viper back-ends as well as a front-end for concurrent separation logic. All our technical results have been formalized in Isabelle/HOL, including the core IVL and its semantics, the semantics of two back-ends for a subset of Viper, and all proofs."}],"quality_controlled":"1","volume":9,"OA_place":"publisher","article_type":"original","title":"Formal foundations for translational separation logic verifiers","publication":"Proceedings of the ACM on Programming Languages","PlanS_conform":"1","ddc":["000"],"_id":"21053","day":"09","publisher":"Association for Computing Machinery","arxiv":1,"author":[{"full_name":"Dardinier, Thibault","last_name":"Dardinier","first_name":"Thibault"},{"last_name":"Sammler","full_name":"Sammler, Michael Joachim","id":"510d3901-2a03-11ee-914d-d9ae9011f0a7","first_name":"Michael Joachim"},{"full_name":"Parthasarathy, Gaurav","last_name":"Parthasarathy","first_name":"Gaurav"},{"first_name":"Alexander J.","last_name":"Summers","full_name":"Summers, Alexander J."},{"full_name":"Müller, Peter","last_name":"Müller","first_name":"Peter"}],"article_processing_charge":"No","date_updated":"2026-02-09T06:25:01Z","status":"public","doi":"10.1145/3704856","publication_status":"published","oa_version":"Published Version","type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"01","OA_type":"hybrid","external_id":{"arxiv":["2407.20002"]},"page":"569-599","publication_identifier":{"issn":["2475-1421"]},"has_accepted_license":"1","citation":{"apa":"Dardinier, T., Sammler, M.

The physical properties of LRDs currently have order-of-magnitude uncertainties, because models to explain the continuum of these sources differ immensely. Here, we leverage the complete selection of red sources in the RUBIES program, supplemented with public PRISM spectra, to study the origin of this V shape. By fitting a broken power law with a flexible inflection point, we find that a large fraction of red Hα emitters at 2 < z < 6 exhibit a strong change in slope, and that all strong inflections appear associated with the Balmer limit (0.3645 μm). Using a simple model of a reddened active galactic nucleus (AGN) with an unobscured scattered-light component, we demonstrate that the observed V shape in LRDs is unlikely to occur at any specific wavelength if the entire continuum is dominated by light from a power-law AGN continuum. In contrast, models with an intrinsic feature at the Balmer limit, such as those that are dominated by an evolved stellar population, can produce the observed spectral shapes, provided that a reddened component picks up sufficiently redward of the break. While no model can comfortably explain the full LRD spectral energy distribution, the common inflection location suggests that a single component consistently dominates the rest-frame UV optical in LRDs, and that this component is associated with T ∼ 10^4 K hydrogen.","lang":"eng"}],"year":"2025","issue":"1","date_published":"2025-12-09T00:00:00Z","oa":1,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"file_date_updated":"2026-02-09T06:39:23Z","scopus_import":"1","language":[{"iso":"eng"}],"citation":{"mla":"Setton, David J., et al. “Little Red Dots at an Inflection Point: Ubiquitous v-Shaped Turnover Consistently Occurs at the Balmer Limit.” <i>The Astrophysical Journal</i>, vol. 995, no. 1, 118, IOP Publishing, 2025, doi:<a href=\"https://doi.org/10.3847/1538-4357/ae1500\">10.3847/1538-4357/ae1500</a>.","ista":"Setton DJ, Greene JE, de Graaff A, Ma Y逸伦, Leja J, Matthee JJ, Bezanson R, Boogaard LA, Cleri NJ, Katz H, Labbe I, Maseda MV, McConachie I, Miller TB, Price SH, Suess KA, van Dokkum P, Wang 王 B冰洁, Weibel A, Whitaker KE, Williams CC. 2025.

However, the lack of observed far-infrared (FIR) emission has proved difficult to reconcile with the implied attenuated luminosity in these models. Here, we utilize deep new Atacama Large Millimeter/submillimeter Array imaging, new and existing JWST/MIRI imaging, and archival Spitzer/Herschel imaging of two of the rest-optically brightest LRDs (z = 3.1 and z = 4.47) to place the strongest constraints on the IR luminosity in LRDs to date. The detections at λrest = 1–4 μm imply flat slopes in the rest-IR, ruling out a contribution from hot (T ≳ 500 K) dust. Similarly, FIR nondetections rule out any appreciable cold (T ≲ 75 K) dust component. Assuming energy balance, these observations are inconsistent with the typical FIR dust emission of dusty starbursts and quasar tori, which usually show a mixture of cold and hot dust. Additionally, our [C ii] nondetections rule out typical dusty starbursts. We compute empirical maximum IR SEDs and find that both LRDs must have log(LIR/L ) 12.2 at the 3σ level. These limits are in tension with the predictions of rest-optical spectrophotometric fits, be they galaxy-only, AGN-only, or composite. It is unlikely that LRDs are highly dust-reddened intrinsically blue sources with a dust temperature distribution that conspires to avoid current observing facilities. Rather, we favor an intrinsically redder LRD SED model that alleviates the need for strong dust attenuation.","lang":"eng"}],"intvolume":"       991","quality_controlled":"1","date_published":"2025-09-12T00:00:00Z","year":"2025","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"oa":1,"_id":"21058","publisher":"IOP Publishing","arxiv":1,"day":"12","ddc":["520"],"PlanS_conform":"1","publication":"The Astrophysical Journal Letters","volume":991,"OA_place":"publisher","article_type":"original","title":"A confirmed deficit of hot and cold dust emission in the most luminous Little Red Dots"},{"year":"2025","date_published":"2025-09-01T00:00:00Z","oa":1,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"quality_controlled":"1","date_created":"2026-01-28T15:24:24Z","intvolume":"       701","abstract":[{"text":"Compact, star-forming galaxies with high star formation rate surface densities (ΣSFR) are often efficient Lyman continuum (LyC) emitters at z ≤ 4.5, likely because intense stellar feedback creates low-density channels that allow photons to escape. Irregular or disturbed morphologies, such as those resulting from mergers, can also facilitate LyC escape by creating anisotropic gas distributions. We investigated the influence of galaxy morphology on LyC production and escape at redshifts 5 ≤ z ≤ 7 using observations from various James Webb Space Telescope (JWST) surveys. Our sample consists of 436 sources, which are predominantly low-mass (∼10^8.15 M\f), star-forming galaxies with ionizing photon efficiency (ξion) values consistent with canonical expectations. Since direct measurements of fesc are not possible during the Epoch of  Reionization (EoR), we predicted fesc for high-redshift galaxies by applying survival analysis to a subsample of LyC emitters from the Low-Redshift Lyman Continuum Survey (LzLCS), selected to be direct analogs of reionization-era galaxies. We find that these galaxies exhibit, on average, modest predicted escape fractions (∼0.04). In addition, we evaluated the correlation between morphological features and LyC emission. Our findings indicate that neither ξion nor the predicted fesc values show a significant correlation with the presence of merger signatures. This suggests that in low-mass galaxies at z ≥ 5, strong morphological disturbances are not the primary mechanism driving LyC emission and leakage. Instead, compactness and star formation activity likely play a more pivotal role in regulating LyC escape.

Here we present a novel NIRCam-based selection method for Pop III galaxies, and carefully validate it through completeness and contamination simulations. We systematically search ≃ 500 arcmin2 across JWST legacy fields for Pop III candidates, including GLIMPSE, which, assisted by gravitational lensing, has produced JWST’s deepest NIRCam imaging thus far. We discover one promising Pop III galaxy candidate (GLIMPSE-16043) at z=6.50 -0.24 +0.03, a moderately lensed galaxy (µ = + 2.9 -0.2 +0.1) with an intrinsic UV magnitude of MUV= -15.89 -0.14 +0.12. It exhibits key Pop III features: strong Hα emission (rest-frame EW 2810 ± 550 Å); a Balmer jump; no dust (UV slope β = −2.34 ± 0.36); and undetectable metal lines (e.g., [O III]; [O III]/Hβ < 0.44), implying a gas-phase metallicity of Zgas/Z⊙ < 0.5%. These properties indicate the presence of a nascent, metal-deficient young stellar population (<5 Myr) with a stellar mass of ≃105 M⊙. Intriguingly, this source deviates significantly from the extrapolated UV–metallicity relation derived from recent JWST observations at z = 4–10, consistent with UV enhancement by a top-heavy Pop III initial mass function or the presence of an extremely metal-poor active galactic nucleus. We also  derive the first observational constraints on the Pop III UV luminosity function at z ≃ 6–7. The volume density of GLIMPSE-16043 (≈10^−4 cMpc−3) is in excellent agreement with theoretical predictions, independently reinforcing its plausibility. This study demonstrates the power of our novel NIRCam method to finally reveal distant galaxies even more pristine than the Milky Way’s most metal-poor satellites, thereby promising to bring us closer to the first generation of stars than we have ever been before."}],"date_created":"2026-01-28T15:25:17Z","intvolume":"       989","DOAJ_listed":"1","month":"08","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"file":[{"file_name":"2025_AstrophysicalJournal_Fujimoto.pdf","date_updated":"2026-02-09T07:57:01Z","file_size":14405059,"relation":"main_file","checksum":"9e08e77ce6d818fafd074e2b6c30bc43","access_level":"open_access","success":1,"date_created":"2026-02-09T07:57:01Z","file_id":"21167","content_type":"application/pdf","creator":"dernst"}],"acknowledgement":"We are grateful to the CEERS, PRIMER, JOF, UNCOVER, and GLIMPSE teams for developing their NIRCam surveys, and to the various JWST and HST surveys acknowledged in Section 3 that enabled our search.

However, disentangling their stellar from AGN light is challenging. Here, we use an empirical approach to infer the average stellar mass of five faint broad-line (BL) Hα emitters at z = 4–5 with BH masses ≈6 × 10^6 M⊙, with a method independent of their spectral energy distribution (SED). We use the deep JWST/NIRcam grism survey “All the Little Things” to measure the overdensities around BL-Hα emitters and around a spectroscopic reference sample of ∼300 galaxies. In our reference sample, we find that megaparsec-scale overdensity correlates with stellar mass. Their large-scale environments suggest that BL-Hα emitters are hosted by galaxies with stellar masses ≈5 × 10^7 M⊙, ≈40 times lower than those inferred from galaxy-only SED fits. Adding measurements around more luminous z ≈ 6 AGNs, we find tentative correlations between line width, BH mass, and the overdensity, suggestive of a steep BH to halo mass relation. The main implications are (1) when BH masses are taken at face value, we confirm extremely high BH to stellar mass ratios of ≈10%, (2) the galaxies of low stellar mass that host growing SMBHs are in tension with typical hydrodynamical simulations, except those without feedback, (3) a 1% duty cycle implied by the host mass hints at super-Eddington accretion, (4) the masses are at odds with an interpretation of the line broadening in terms of high stellar density, (5) our results imply a luminosity-dependent diversity of galaxy masses, environments, and SEDs among AGN samples."}],"title":"Environmental evidence for overly massive Black Holes in low-mass galaxies and a Black Hole–Halo mass relation at z ∼ 5","article_type":"original","volume":988,"OA_place":"publisher","publication":"The Astrophysical Journal","PlanS_conform":"1","ddc":["520"],"publisher":"IOP Publishing","arxiv":1,"day":"29","_id":"21062"},{"intvolume":"       537","abstract":[{"text":"We report the detection of a 13σ Hα emission line from HDF850.1 at z = 5.188 ± 0.001 using the FRESCO (First Reionization Era SpectroscopicallyComplete Observations) NIRCam F444W grism observations. Detection of Hα in HDF850.1 is noteworthy, given its high far-infrared (IR) luminosity, substantial dust obscuration, and the historical challenges in deriving its redshift.\r\nHDF850.1 shows a clear detection in the F444W imaging data, distributed between a northern and southern component, mirroring that seen in [C II] from the Plateau de Bure Interferometer. Modelling the spectral energy distribution of each component separately, we find that the northern component has a higher mass, star formation rate (SFR), and dust extinction than the southern component. The observed Hα emission appears to arise entirely from the less-obscured southern component and shows a similar \u0004v∼ + 130 km s −1 velocity offset to that seen for [C II] relative to the source systemic redshift. Leveraging Hα-derived redshiftsfrom FRESCO observations, we find that HDF850.1 isforming in one of the richest environments identified to date at z > 5, with 100 z = 5.17–5.20 galaxies distributed across 13 smaller structures and a ∼(15 cMpc)3 volume. Based on the evolution of analogous structures in cosmological simulations, the z = 5.17–5.20 structures seem likely to collapse into\r\na single > 1014M cluster by z ∼ 0. Comparing galaxy properties forming within this overdensity with those outside, we find the masses, SFRs, and UV luminosities inside the overdensity to be clearly higher. The prominence of Hα line emission from HDF850.1 and other known highly obscured z > 5 galaxies illustrates the potential of NIRCam-grism programs to map both\r\nthe early build-up of IR-luminous galaxies and overdense structures.","lang":"eng"}],"date_created":"2026-01-28T15:25:53Z","quality_controlled":"1","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"oa":1,"date_published":"2025-02-01T00:00:00Z","issue":"2","year":"2025","ddc":["520"],"_id":"21063","day":"01","arxiv":1,"publisher":"Oxford University Press","OA_place":"publisher","volume":537,"article_type":"original","title":"Mapping dusty galaxy growth at z > 5 with FRESCO: Detection of Hα in submm galaxy HDF850.1 and the surrounding overdense structures","publication":"Monthly Notices of the Royal Astronomical Society","PlanS_conform":"1","status":"public","doi":"10.1093/mnras/staf030","publication_status":"published","oa_version":"Published Version","type":"journal_article","article_processing_charge":"Yes","author":[{"first_name":"Thomas","full_name":"Herard-Demanche, Thomas","last_name":"Herard-Demanche"},{"full_name":"Bouwens, Rychard J","last_name":"Bouwens","first_name":"Rychard J"},{"last_name":"Oesch","full_name":"Oesch, Pascal A","first_name":"Pascal A"},{"first_name":"Rohan P","last_name":"Naidu","full_name":"Naidu, Rohan P"},{"first_name":"Roberto","last_name":"Decarli","full_name":"Decarli, Roberto"},{"first_name":"Erica J","last_name":"Nelson","full_name":"Nelson, Erica J"},{"first_name":"Gabriel","last_name":"Brammer","full_name":"Brammer, Gabriel"},{"full_name":"Weibel, Andrea","last_name":"Weibel","first_name":"Andrea"},{"first_name":"Mengyuan","last_name":"Xiao","full_name":"Xiao, Mengyuan"},{"first_name":"Mauro","last_name":"Stefanon","full_name":"Stefanon, Mauro"},{"full_name":"Walter, Fabian","last_name":"Walter","first_name":"Fabian"},{"full_name":"Matthee, Jorryt J","last_name":"Matthee","id":"7439a258-f3c0-11ec-9501-9df22fe06720","orcid":"0000-0003-2871-127X","first_name":"Jorryt J"},{"full_name":"Meyer, Romain A","last_name":"Meyer","first_name":"Romain A"},{"first_name":"Stijn","full_name":"Wuyts, Stijn","last_name":"Wuyts"},{"last_name":"Reddy","full_name":"Reddy, Naveen","first_name":"Naveen"},{"first_name":"Lucie","full_name":"Rowland, Lucie","last_name":"Rowland"},{"last_name":"van Leeuwen","full_name":"van Leeuwen, Ivana","first_name":"Ivana"},{"first_name":"Pablo Arrabal","full_name":"Haro, Pablo Arrabal","last_name":"Haro"},{"full_name":"Dannerbauer, Helmut","last_name":"Dannerbauer","first_name":"Helmut"},{"first_name":"Alice E","last_name":"Shapley","full_name":"Shapley, Alice E"},{"full_name":"Chisholm, John","last_name":"Chisholm","first_name":"John"},{"first_name":"Pieter","full_name":"van Dokkum, Pieter","last_name":"van Dokkum"},{"last_name":"Labbe","full_name":"Labbe, Ivo","first_name":"Ivo"},{"full_name":"Illingworth, Garth","last_name":"Illingworth","first_name":"Garth"},{"first_name":"Daniel","last_name":"Schaerer","full_name":"Schaerer, Daniel"},{"last_name":"Shivaei","full_name":"Shivaei, Irene","first_name":"Irene"}],"date_updated":"2026-02-09T08:50:55Z","department":[{"_id":"JoMa"}],"has_accepted_license":"1","citation":{"mla":"Herard-Demanche, Thomas, et al. “Mapping Dusty Galaxy Growth at z &#62; 5 with FRESCO: Detection of Hα in Submm Galaxy HDF850.1 and the Surrounding Overdense Structures.” <i>Monthly Notices of the Royal Astronomical Society</i>, vol. 537, no. 2, Oxford University Press, 2025, pp. 788–808, doi:<a href=\"https://doi.org/10.1093/mnras/staf030\">10.1093/mnras/staf030</a>.","ista":"Herard-Demanche T, Bouwens RJ, Oesch PA, Naidu RP, Decarli R, Nelson EJ, Brammer G, Weibel A, Xiao M, Stefanon M, Walter F, Matthee JJ, Meyer RA, Wuyts S, Reddy N, Rowland L, van Leeuwen I, Haro PA, Dannerbauer H, Shapley AE, Chisholm J, van Dokkum P, Labbe I, Illingworth G, Schaerer D, Shivaei I. 2025.

First, we generalize the existing results of identifiability with the score to additive noise models with minimal requirements on the causal mechanisms. Second, we establish conditions for inferring causal relations from the score even in the presence of hidden variables; this result is two-faced: we demonstrate the score’s potential as an alternative to conditional independence tests to infer the equivalence class of causal graphs with hidden variables, and we provide the necessary conditions for identifying direct causes in latent variable models. Building on these insights, we propose a flexible algorithm for causal discovery across linear, nonlinear, and latent variable models, which we empirically validate."}],"intvolume":"       275","date_created":"2026-01-29T14:19:09Z","title":"Score matching through the roof: Linear, nonlinear, and latent variables causal discovery","OA_place":"publisher","volume":275,"publication":"Proceedings of the Fourth Conference on Causal Learning and Reasoning","ddc":["000"],"day":"01","arxiv":1,"publisher":"ML Research Press","_id":"21066"}]
