Uncovering the Physical Origins of Black Holes in the Milky Way for Astronomical Surveys
The observational landscape of stellar-mass black holes (BHs) in the Milky Way is expanding beyond X-ray binaries, with Gaia DR4 and Roman expected to open new windows onto BH populations.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.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.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…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…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.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).Cross-Modal Solar Image Synthesis: Adapting the Surya Foundation Model from He I 10830 Å to EUV Translation and Coronal Hole Segmentation
The long observational record of He I 10830 Å offers a means to investigate solar morphology before modern extreme-ultraviolet (EUV) imaging.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.A concordance model of neutron star kicks
Neutron stars (NSs) receive natal kicks during supernovae that affect their survival in binaries and motion through the Galaxy.Stars Would Remember a Recent Gravitational Transition: Testing G-step Resolutions of the Hubble Tension with Red Dwarfs
We test the hypothesis that Newton's gravitational constant underwent a rapid transition approximately $73$-$130\,{\rm Myr}$ ago, as proposed in some resolutions of the Hubble tension.Chemical complexity in feedback from supernova remnants: first detection of PO+ in IC443 and W44
Supernova remnant (SNR) may shape the physical and chemical properties of star formation.Neutrino flavor instabilities intermediate between slow and fast
The neutrino flavor composition in supernovae and neutron star mergers is shaped by flavor instabilities, which are commonly classified into three types: slow (SFI), fast (FFI), and collisional (CFI).Collapse-accelerated small-scale dynamos in the first stars and galaxies
Here, we explore magnetic field amplification by the small-scale dynamo (SSD) during the formation of the first stars and galaxies.Towards breaking the degeneracy between stellar ages and unresolved multiplicity
Stellar age is the central desirable parameter we need to disentangle different Galactic formation scenarios.Tracing star formation across the Rosette nebula using deep Spitzer imaging
We present a deep large-scale infrared survey of young stellar objects in the Rosette Nebula.MAGiDiff: Sampling the Photospheric Vector Field from UV/EUV Filtergrams
Photospheric vector magnetic fields are foundational to modeling, understanding, and forecasting solar activity.Gaia neutron stars: demographics, birth rates, and connections to other neutron star populations
Gaia DR3 revealed a new class of neutron stars (NSs) in au-scale orbits with solar-type companions.
