The DECam MAGIC Survey: Uncovering the Tidal Tails of the Crater II Dwarf Galaxy

Kaia R. Atzberger, Andrew B. Pace, Nitya Kallivayalil +27

Crater II (CraII), a large and low-density dwarf spheroidal galaxy, has unusual observed properties that are difficult to reproduce in cold dark matter simulations. Ongoing tidal d…

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…

DELVE-DEEP Survey: The Faint Satellite System of NGC 55

Jonah Medoff, Burçin Mutlu-Pakdil, Jeffrey L. Carlin +24

We report the first comprehensive census of the satellite dwarf galaxies around NGC 55 ( Mpc) as a part of the DECam Local Volume Exploration DEEP (DELVE-DEEP) survey. NGC 55…

The DECam MAGIC Survey: A Wide-field Photometric Metallicity Study of the Sculptor Dwarf Spheroidal Galaxy

Fabrícia O. Barbosa, Anirudh Chiti, Guilherme Limberg +26

The metallicity distribution function and internal chemical variations of a galaxy are fundamental to understand its formation and assembly history. In this work, we analyze photom…

Not-so-heavy metal(s): Chemical Abundances in the Ultra-faint Dwarf Galaxies Eridanus IV and Centaurus I

Mairéad E Heiger, Alexander P Ji, Ting S Li +18

We present detailed chemical abundances of the brightest star in each of the ultra-faint dwarf galaxies Eridanus IV and Centaurus I using high-resolution Magellan/MIKE spectroscopy…

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).…
