Life in the Cosmic Neighbourhood: Galactic Habitable Zones in the EAGLE Simulations
When and where is life most likely to form in the universe?Complex Organic Molecules in Protostars with ALMA Spectral Surveys (COMPASS) III. CH$_3$OH isotopic fractionation in the low-mass protostar BHR71-IRS1
[Abridged] Methanol is a complex organic molecule detected in both ice and gas toward star-forming regions.The Rogue One: A Dark Matter-Dominated Dwarf in the Trail of Dark Matter-Deficient Galaxies
We present the first measurement of the stellar velocity dispersion of LEDA 4014647, a compact dwarf galaxy spatially aligned with the NGC 1052 trail, a linear chain of dark matter-deficient…Barium and europium abundances from the Gaia-ESO Survey using The Cannon
Neutron-capture element abundances encode the time-dependent interplay between slow (s-) and rapid (r-) nucleosynthetic processes and provide critical constraints on Galactic chemical evolution.Spectral Energy Distribution and Polarimetric Properties of Dust in the Interstellar Comet 3I/ATLAS
The interstellar comet 3I/ATLAS exhibits unusual polarimetric properties compared with Solar System comets, while constraints on its fundamental physical properties, such as dust albedo and…Large-Scale Stellar Bars and Nuclear Activity in Narrow-Line Seyfert 1 Galaxies
We present a statistical comparison between barred and unbarred narrow-line Seyfert 1 galaxies (NLS1s) to investigate the role of large-scale stellar bars in fueling AGN with low-mass black holes.SPHERE/ZIMPOL observations of the symbiotic system R Aquarii. II. Dynamics of the dust in the Mira wind and the Halpha gas in the jet
R Aqr is a resolved symbiotic Mira binary and a prototype target for the study of complex hydrodynamic processes including dust-driven mass loss, mass transfer, accretion, and jet outflows and the…Spatio-temporal progression of star formation in the Carina OB1 association
The Carina OB1 association, harboring the famous Carina Nebula near its center, is the most massive, well-studied OB association in our Galaxy.Large offsets of double-neutron-star mergers: degeneracies and implications for host associations
The projected offset of a Gamma-Ray Burst (GRB) from its host galaxy is an important diagnostic of its physical origin, where the host associations are usually evaluated through chance-coincidence…A Brush with Turbulence: Probing the ICM Dynamics in the Merging Toothbrush Cluster using XRISM
The Toothbrush Cluster (1RXS J0603.3+4214) is known for its northern radio relic, radio halo, and highly disturbed X-ray morphology.AI Agents as a Research Team: A Human-Supervised Case Study in Stellar Spectroscopy
We present a qualitative case study of a human-supervised team of specialized AI agents supporting an astronomy research project.ALMA Observations of Molecular Complexity in the Large Magellanic Cloud: The N83 Star-Forming Region
We report the results of the 1.2 mm continuum and molecular line $\sim$0.1 parsec-scale observations with the Atacama Large Millimeter/submillimeter Array of two fields in the star-forming region…Stellar parameters and abundances for 3.2 million DESI DR1 spectra using machine learning
We present a machine-learning pipeline for determining stellar parameters and chemical abundances from spectra observed by the Dark Energy Spectroscopic Instrument (DESI).Finding the evolutionary link between ULIRGs and radio galaxies
Ultraluminous infrared galaxies (ULIRGs) are the remnants of the major mergers of gas-rich galaxies.Feedback-Driven Interaction of Expanding Molecular Clouds in the LDN 1204-Sh2 145-Sh2 140 Complex
We present a multi-wavelength study of an extended molecular cloud hosting the LDN 1204, Sh2 145, and Sh2 140 regions to investigate the interplay between stellar feedback, cloud dynamics, and star…Diffuse Galactic Backgrounds with SPHEREx: A Pilot Study of Background Modeling and Its Impact on Extinction
We present a spectral analysis of diffuse Galactic background emission using SPHEREx data in a pilot Galactic-plane field, where uncertainty in the estimation of the diffuse infrared background is a…Power-law Coupling and Mock Validation of a Surface-density Anisotropy Diagnostic for 85 Rich Galaxy Clusters
We assess a surface-density anisotropy diagnostic, $A_{\rm ani}$, and its association with the slope $α$ of a power-law galaxy profile.The variable mass-loss in low-mass red giant stars: Chromospheric motion across stellar evolution in 47 Tuc
Mass-Loss (ML) is a critical process that remains poorly understood despite its broad implications across astrophysics.The 200-300 GHz Survey for 18 Class II Disks in the Ophiuchus Star-Forming Complex
We measured the 198-310 GHz flux densities of 18 Class II protoplanetary disks in the Ophiuchus star-forming complex using the Submillimeter Array (SMA).No Convincing Evidence for Tidal Binary Clusters in the Galaxy
The existence of tidal binary clusters (TBCs) in the Milky Way has been repeatedly suggested using Gaia DR3 astrometry and recent catalogs of binary clusters and groups.
