Beyond the Local Group. I. Cosmic Filaments Govern the Spatial Alignments of Galaxy Pairs

The Astrophysical Journal
Using a large observational sample from the Sloan Digital Sky Survey, we investigate the spatial alignment between galaxy pairs and their local cosmic filaments. Focusing on pairs with stellar masses and separations comparable to the Milky Way–Andromeda (

Discovery of a Weak CN Spectral Absorption Feature in Red Supergiant Stars in the Andromeda (M31) and Triangulum (M33) Galaxies

The Astrophysical Journal
Using Keck DEIMOS spectra of stars in the Andromeda (M31) and Triangulum (M33) galaxies, selected from the large multiband (near-ultraviolet, visible light, and near-infrared) Hubble Space Telescope surveys PHAT and PHATTER, respectively, we have ...

The habitability trade-off: Chemical decoupling and quenching in massive galaxies

Astronomy & Astrophysics
Massive galaxies experience complex evolutionary processes, including mergers and gas accretion, which can disrupt the chemical equilibrium between their stellar and gaseous components. Using the IllustrisTNG (TNG100) simulation at z = 0, we investigated

Prospects for Detecting Gaps in Globular Cluster Stellar Streams in External Galaxies with the Nancy Grace Roman Space Telescope

The Astrophysical Journal
Stellar streams form through the tidal disruption of satellite galaxies or globular clusters orbiting a host galaxy. Globular cluster streams are exciting since they are thin (dynamically cold) and therefore sensitive to perturbations from low-mass ...

The Karl G. Jansky Very Large Array Local Group L-Band Survey (LGLBS)

The Astrophysical Journal Supplement Series
We present the Local Group L -Band Survey, a Karl G. Jansky Very Large Array (VLA) survey producing the highest-quality 21 cm and 1–2 GHz radio continuum images to date, for the six VLA-accessible, star-forming, Local Group galaxies. Leveraging the VLA’s

Rotational Kinematics in the Globular Cluster System of M31: Insights from Bayesian Inference

The Open Journal of Astrophysics
As ancient stellar systems, globular clusters (GCs) offer valuable insights into the dynamical histories of large galaxies. Previous studies of GC populations in the inner and outer regions of the Andromeda Galaxy (M31) have revealed intriguing ...
