A cosmic filament catalog for COSMOS-Web Data Release 1 across 0.5 < z < 3.5
Cosmic filaments represent the environments in which most galaxies form and evolve.A Robust Estimator for the Lyman-$α$ Forest 1D Power Spectrum at High Redshift
The Lyman-$α$ (Ly$α$) forest flux power spectrum $P(k)$ is sensitive to a range of astrophysical and cosmological effects, including the thermal state of and large-scale fluctuations in the…Odd radio circle J1555+2726: Observational evidence for shock re-acceleration of fossil plasma
Odd radio circles (ORCs) are peculiar extragalactic sources recently discovered.AMICO galaxy clusters in KiDS-1000: Cosmological constraints from the two-point correlation function
In this paper we study the clustering properties of an optically identified photometric galaxy cluster catalogue from KiDS-1000.HETDEX [OII] galaxies at $z \le 0.48$: Growth of structures from power spectrum multipoles
We use the monopole and quadrupole power spectra of [\ion{O}{2}]-emitting galaxies in the HETDEX Public Data Release 1 to constrain the growth of cosmic structures at $z\le0.48$.Optimal galaxy magnification: generalized fundamental-plane residuals and number counts are all you need
Weak-lensing magnification complements cosmic shear through its effects on galaxy fluxes, sizes, and number counts.The THESAN-ZOOM project: the delayed rise of Lyman continuum escape fractions in bursty high-redshift galaxies
The ionizing radiation that galaxies release into their surroundings depends on whether efficient Lyman continuum (LyC) escape coincides with strong photon production.The black hole-galaxy correlations of the 12 micron local AGN sample: a NuSTAR perspective
The M-sigma correlation of inactive galaxies plays a crucial role in estimating the black hole mass (MBH) in active galactic nuclei (AGN): 1) it is used to calibrate the reverberation mapping (RM)…The PAU Survey: Active galactic nucleus galaxies in galaxy pairs
Leveraging the high-precision photometric redshifts of the Physics of the Accelerating Universe Survey (PAUS), we aim to investigate the connection between active galactic nuclei (AGNs) and galaxy…Axion detection in the non-Markovian noise
The detection of axion dark matter poses a significant challenge due to its exceptionally weak coupling to standard-model particles.Kinematically isolating intracluster light in AS1063: a distinct stellar population tracing the dark matter core
We present a technique using integral-field spectroscopy to kinematically isolate intracluster light (ICL) from the brightest cluster galaxy (BCG), enabling insights into their contrasting stellar…PIANISTpy: A JAX-based Python package for velocity-anisotropic astrophysical equilibrium models
The hierarchical assembly of dark matter haloes and galaxies via mergers and anisotropic mass accretion naturally imprints non-trivial velocity anisotropy onto haloes and galaxies, an empirical fact…Constraints on Reionization from Planck Low-$\ell$ EE Polarization and the Lyman-Series Forests
CMB measurements tightly constrain the Thomson scattering optical depth ($τ_{\rm es}$), but they still permit a broad range of degenerate reionization histories.Not so Fast: Revised Calibration of SIDM Core Collapse
Self-interacting dark matter (SIDM) haloes undergo gravothermal evolution whose late-time behaviour is central to predictions for dense substructure and black-hole seed formation.Searching for lensed gravitational waves with unlensed templates
Gravitational lensing can split the signal of a binary merger into two images, which either overlap and interfere or arrive as separate events.ERGO-ML and how to directly infer the multi-temperature nature of intra-cluster gas: simulation-based inference with TNG-Cluster
Though galaxy clusters are virialized and mostly in thermodynamic equilibrium, their internal gas thermodynamics are complex.Graph Neural Networks for Astrophysics and Cosmology
Physics seldom makes breakthroughs when we consider objects only in isolation.Annihilation feedback on elastic scattering in self-interacting dark matter
Sizable dark-matter self-interactions, motivated by observations of galactic structure, often arise from the exchange of light force mediators.Optical and Ultraviolet Emission from the Gas Photoionized by Gaia BH3: Archival Constraints and Predictions for the 2029 Periastron
Gaia BH3, a $32.7\,M_\odot$ black hole (BH) on an 11.6-yr, $e=0.73$ orbit around a metal-poor giant at $\approx590$ pc, accretes from its wind.Modular Bayesian Inference for Partially Misspecified Mixtures with Uncertain Class Labels
Scientific inference often involves observations from multiple latent populations whose class memberships are uncertain and must be inferred from available data.
