Warped & Hooked: Mapping the Magellanic Clouds in 3D using Red Clump stars
Slater J. Oden, David L. Nidever, Joshua Povick +18
The Large and Small Magellanic Clouds (LMC and SMC) are the Milky Way's nearest interacting galaxy pair, offering a unique laboratory for studying tidal effects on galactic disks.…
The Draco Dwarf Spheroidal Galaxy in the First Year of DESI Data
J. Ding, C. Rockosi, Ting S. Li +40
We investigate the spatial distribution, kinematics, and metallicity of stars in the Draco dwarf spheroidal galaxy using data from the Dark Energy Spectroscopic Instrument (DESI).…
A DECADE of dwarfs: first detection of weak lensing around spectroscopically confirmed low-mass galaxies
Chun-Hao To, Chihway Chang, Dhayaa Anbajagane +35
We present the first detection of weak gravitational lensing around spectroscopically confirmed dwarf galaxies, using the large overlap between DESI DR1 spectroscopic data and DECA…
DECADE+DES Y3 Weak Lensing Mass Map: A 13,000 deg View of Cosmic Structure from 270 Million Galaxies
M. Gatti, D. Anbajagane, C. Chang +37
We present the largest galaxy weak lensing mass map of the late-time Universe, reconstructed from 270 million galaxies in the DECADE and DES Year 3 datasets, covering 13,000 square…
DELVE-ing into the Milky Way's Globular Clusters: Assessing extra-tidal features in NGC 5897, NGC 7492, and testing detectability with deeper photometry
A. Chiti, K. Tavangar, P. S. Ferguson +22
Extra-tidal features around globular clusters (GCs) are tracers of their disruption, stellar stream formation, and their host's gravitational potential. However, these features rem…
Spectroscopic Analysis of Pictor II: a very low metallicity ultra-faint dwarf galaxy bound to the Large Magellanic Cloud
A. B. Pace, T. S. Li, A. P. Ji +30
We present Magellan/IMACS and Magellan/MIKE spectroscopy of the ultra-faint dwarf (UFD) galaxy Pictor~II (Pic~II) that is located only 12 kpc from the Large Magellanic Cloud (LMC).…
