GetGaia 2.0: automatic membership and systemic motions of stellar systems with Gaia
We present GetGaia 2.0, a public Python package that retrieves the Gaia data around a stellar system and selects its member stars automatically.Dust Survival in Lensed Quiescent Galaxies at $z>1$ Depends on How They Quench
The interstellar medium of massive quiescent galaxies holds key clues to how they quench, yet remain poorly understood.An automated photometric pipeline for measuring the corotation radius of spiral galaxies
The corotation radius R_CR of a spiral galaxy marks the radius where the angular speed of the spiral pattern matches the orbital speed of the disk material.The vertical distribution of molecular gas in the fourth quadrant of the Milky Way
The vertical distribution of molecular gas in the Milky Way disk is poorly studied, especially in the 4th quadrant and the far side of the Galaxy.Tidal Evolution of Satellite Dwarf Galaxies. I. Tidal Tracks of Stellar Mass and Structure
Satellite dwarf galaxies are reshaped by the tidal field of their host, a process that may account for part of the structural diversity of the observed dwarf population.Extreme Multiwavelength Variability in the Recurrent Intermediate-type Changing-look Seyfert Galaxy SDSS J234728.73+242745.7
We report the discovery of the Seyfert galaxy J234728.73+242745.7 as a recurrent intermediate-type CLAGN with extreme optical/UV variability.Constraining Dust Properties Along the Minor Axis of Andromeda
Previous studies of dust emission in M31 based primarily on Herschel data have reported inconsistent radial trends in the dust emissivity index ($β$), partly due to limited wavelength coverage and…HI Emission Recovery in the Low-Redshift Radio Population: Host-Galaxy and Radio-Luminosity Dependence in FASHI and LoTSS
Overlapping blind 21 cm and wide-area low-frequency continuum surveys make it possible to measure which radio sources an untargeted HI survey recovers.Probing the Faint Outskirts of Star-Forming Galaxies with 1<z<9 Using Stacked Images
We present a systematic study of the faint outer light profiles of star-forming galaxies using deep JWST/NIRCam imaging from the CEERS, JADES, and PRIMER surveys.The TNG50-SKIRT Atlas: Multi-wavelength properties of galaxy discs in the TNG50 simulation
We investigate the wavelength dependence of disc scale lengths in galaxies from the TNG50-SKIRT Atlas (TSA), and assess whether the simulated galaxies reproduce the structural properties and scaling…GAMA-23 deep field with uGMRT Band-2: source catalogue and source count
We present the low-frequency GAMA-23 field of the Galaxy and Mass Assembly (GAMA) survey with upgraded Giant Meterwave Radio Telescope (uGMRT) observations in Band-2 ($120-250$ MHz).Does Topology-Dependent Chemistry Influence the Interstellar PAH Inventory? Insights from the Absence of Cyanotriphenylenes
Although a set of polycyclic aromatic hydrocarbons (PAHs) has recently been identified in the cold dark cloud TMC-1, several common PAH motifs remain absent, leaving the origin of this apparent…A detailed star formation history of the distant Milky Way satellite Canes Venatici I: An old dwarf spheroidal forming most of its stars after reionisation
Canes Venatici I (CVnI) is a distant Milky Way (MW) dwarf spheroidal (dSph) satellite.Metamorphic novae. I. Gaia22alz -- Violent relaxation starting from static evolution
Gaia22alz (nova Vel 2022) shows characteristic properties in its light curves and spectral evolution similar to slow novae HR Del, V723 Cas, and V5558 Sgr.Black Hole Mass Estimation of a Background Quasar in the Vicinity of the cD Galaxy Holm 15A
This study analyzes spectra from the central region of the galaxy cluster Abell 85 observed with GTC/OSIRIS, focusing on the cD galaxy Holm 15A and the point-like X-ray source SDSS…UV spectra of little red dots: Broad-line N/C, gas recycling and black hole masses
Radiative-transfer models of supermassive black holes accreting inside dense gas cocoons reproduce the X-ray-to-near-infrared spectral energy distribution of "little red dots" (LRDs) using the code…Beyond just a torus? Re-contextualising the AGN type paradigm using data-driven host galaxy quenching histories
The orientation of a dusty torus within a unified model explains the presence (Type-1) or absence (Type-2) of broad emission lines in Active Galactic Nuclei (AGN) spectra.HLA-Net: A Physics-Guided Skeleton-Based Framework for Automatic Gravitational Arc Detection in Astronomical Images
Gravitational arcs produced by strong gravitational lensing provide a unique approach for investigating dark matter distribution, galaxy cluster mass reconstruction and the structure of the Universe.The PAU Survey: Self-supervised image denoising for flux-preserving photometry
Deep photometric surveys increasingly rely on low signal-to-noise imaging, where noise affects source detection, flux measurements, photometric redshifts, and sample selection.Brewing another binary in the Teapot: Nandou=Phi Sagittarii
The iconic Teapot asterism in Sagittarius is particularly rich in intermediate-mass stars in multiple systems.
