Simulation-Informed High-Velocity Dark Matter in the Effective Theory of Direct Detection
The interpretation and reach of direct detection (DD) experiments depend sensitively on the local dark matter (DM) velocity distribution, particularly its high-velocity tail.Discovery of a Broad-Line Active Galactic Nucleus at $z = 9.98$
The James Webb Space Telescope (JWST) has uncovered a previously unexplored population of faint active galactic nuclei (AGNs) in the early Universe.A combined HST and JWST analysis of the stellar population in Draco II
Draco II (Dra II) is one of the faintest and most metal-poor Milky Way satellites known, yet its nature as either an ultra-faint dwarf galaxy or an extended globular cluster remains debated.Unveiling the correlation between the UV 2175 Å dust attenuation bump, PAH emission, and gas-phase metallicity at cosmic noon
The UV 2175 Å attenuation bump is one of the most prominent yet poorly understood features of galaxy attenuation curves.Ammonia Fitting of Multiple Velocity Components in High-Mass Star-Forming Regions
We perform a multiple velocity component analysis of ammonia (NH$_3$) gas from KEYSTONE, a Green Bank Telescope survey covering 11 giant molecular clouds (GMCs) at distances from 0.7 to 2.7 kpc.Link between the properties of circumgalactic outflows and the recent star formation history of their host galaxies
Galactic outflows play a key role in galaxy evolution, yet their connection to the star formation history of their host galaxies remains poorly constrained.The MIni-Halos in MIni-Clusters (MIMIC) project: New insights into the origin of mini-halos from a LOFAR, uGMRT, and MeerKAT study of diffuse radio emission in Abell 496 and ZwCl 235
We aim at investigating the presence of diffuse radio emission in low-mass (M$_{500}\leq3\times10^{14}$ M$_{\odot}$), relaxed galaxy clusters.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.FAUST XXXII. Chemically layered structures and ionisation in the disk and envelope of NGC 1333 IRAS 4C
Recent molecular line observations with high spatial resolutions have revealed vertical chemical stratification in Class I/II disks (i.e. chemical composition changing with height in the vertical…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.KROME-X: a GPU-ready library for chemistry and microphysics in astrophysical simulations
KROME is a Python pre-processor that writes a complete Fortran solver of chemistry and microphysics for each chemical network, widely used in astrophysical simulations.The H IX galaxy survey IV: What does the molecular gas reveal in HI eXtreme galaxies
Galaxies with extreme amounts of neutral atomic hydrogen (HI), known as HI-eXtreme (HIX) galaxies, paradoxically exhibit normal or low star formation rates.Velocity-resolved Ionization Mapping of the Broad-line Region. II. Signatures of Eccentric Broad-line Regions from a Quantitative Photoionization-Based Model
Velocity-resolved reverberation mapping (RM) is one of the most powerful tools for probing the geometry and kinematics of the broad-line region in active galactic nuclei.The DARWIN Project: Cosmological Simulations of Galaxy Formation down to Dwarf Scales in Diverse Environments
We present the DARWIN project, a suite of cosmological simulations with RAMSES to study dwarf-galaxy formation and evolution across diverse environments.A high-Galactic-altitude scattering screen: scintillation from Globular Cluster pulsar M53A
While known interstellar scattering screens are largely confined to the Galactic disk, the scattering properties of the circumgalactic medium (CGM) in the deep Galactic halo have remained unexplored.Kinematic structure and age of a Scorpius--Centaurus subcomponent: implications for PDS 70 planetary system
PDS~70, the only system with two directly imaged protoplanets embedded in their natal disk, is a benchmark for giant-planet formation theory.The Solar System through dust maps. Encounter statistics with interstellar gas
During its orbit around the Milky Way, the Solar System crosses different environments, including dense ISM regions.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.Effect of galaxy mergers on dust masses
Dust mass (M$_{Dust}$) is one of the key physical properties of galaxies that track the cold interstellar medium.
