An all-sky catalogue of Be transition stars from WISE and Gaia
We present an all-sky catalogue of classical Be stars undergoing transitions between quiescent B-type and active Be-star phases, based on Gaia DR3 astrometry and multi-epoch mid-infrared photometry…The Stellar-Mass Dependence of Feedback-Driven Outflows in DESI DR1 Star-Forming Galaxies
Stellar feedback plays a key role in regulating star formation and shaping the evolution of star-forming galaxies.See you again: an $80^\circ$ NGC~5466 stellar stream and its constraints on the Galactic dark halo mass
Using \textit{Gaia} Data Release 3 combined with Dark Energy Spectroscopic Instrument Legacy Imaging Survey Data Release 9 and Panoramic Survey Telescope and Rapid Response System Data Release 2, we…Two Fast Radio Burst Candidates Detected in the RATAN-600 Blind Survey
We report the detection of two single dispersed pulses with widths of about 6.7\,ms and 15.6\,ms and flux densities of about 0.8 and 1.7\,Jy.An Empirical Temperature Relation for Chemical Abundances in AGN
We present for the very first time the empirical temperature structure of the narrow line region (NLR) clouds of active galactic nuclei (AGNs) based on a sample of [N II] and [O III] auroral line…Kinematic analysis of the TNG50 Milky Way and Andromeda analogues
We investigate whether Ogorodnikov-Milne (O-M) parameters can serve as kinematic tracers of spiral structure in four Milky Way- and Andromeda-like disc galaxies from the TNG50-1 simulation at z=0.J-PAS: Exploring the connection between local environment and the triggering of bursty star formation in Extreme Emission Line Galaxies
[Abridged]Extreme Emission Line Galaxies (EELGs) are compact, low-mass systems undergoing intense bursts of star formation, whose physical conditions resemble those of galaxies in the early Universe.Decomposition of disk and jet optical emission: Case of PKS~1510-089 and PKS~0736+017
Measuring BLR size and black hole mass of jetted quasars with strong radio emission is challenging due to the contribution from non-thermal synchrotron radiation from the jet in the optical continuum.What can strong lensing recover in edge-on disc galaxies? A mock study based on TNG50 simulations
Strong gravitational lensing tightly constrains the projected mass within the Einstein aperture, but what else imaging alone can recover for edge-on disc lenses remains untested against known truth.GALACTIC CENTERS AS TRACERS OF GALAXY EVOLUTION: Zooming from galaxy large-scale properties into their central massive black holes
During the workshop ''Galactic Centers as tracers of galaxy evolution'' (Lorentz Center, Leiden), we reviewed one of the most debated questions in the field of galaxy evolution: the connection…Molecular gas in the disks and tails of ram pressure stripped Coma galaxies
We present new IRAM 30 m observations of CO(1-0) and CO(2-1) emission in five Coma cluster galaxies undergoing ram pressure stripping.Statistical Modeling of Foreground Galactic Cirrus for Diffuse Halo Light Measurement
Galactic cirrus, the diffuse Milky Way starlight scattered by interstellar dust, has become a major source of systematic uncertainty in measurements of extragalactic diffuse emission at ultra-low…A Cepheid-based Distance to the Type 1 Seyfert NGC 3783
We present a Cepheid-based distance to the Type 1 Seyfert NGC 3783 using the Hubble Space Telescope.Stellar wind variability in OB stars and its effect on mass-loss determinations
Virtually all stellar winds of OB stars exhibit variability in one spectral diagnostic or another.A Physics Informed Neural Network Approach to Decipher Environmental Confinement of Molecular Clouds in the Third Galactic Quadrant
Recent high-sensitivity and high-resolution surveys of the Third Galactic Quadrant [$219.75 \leq l \leq 229.75$ and $-5.25 \leq b \leq 5.25$], such as the Milky Way Imaging Scroll Painting ( MWISP)…VLITE Observations of the Hubble Ultra Deep Field
We present 136 hr of 340 MHz observations of the Hubble Ultra Deep Field (HUDF) conducted with the VLA Low-band Ionosphere and Transient Experiment (VLITE), collected commensally with…Episodic Protostellar Outflows: A Proper Motion Study in Serpens South
Serpens South is a notable protostellar cluster with signatures of recent star formation, including a high protostellar fraction.Chemical and dynamical evolution of prestellar cores, the dawn of star and planet formation
Studying prestellar cores is crucial to understanding the formation of stellar and planetary systems.Episodic Star Formation - II. The Origin of the Fundamental Metallicity Relation
The Fundamental Metallicity Relation (FMR) extends the mass-metallicity relation (MZR) by including star formation rate (SFR) as a third parameter.How bursty star formation shapes spectral diversity at high redshifts: breaking degeneracies in early galaxy formation
JWST has revealed an unexpected abundance of z>10 galaxies and striking spectral diversity.
