Deep Imaging of Grus II and Horologium II: Structure and Extent of Two Ultra-Faint Milky Way Satellites
Deepthi S. Prabhu, David J. Sand, Anirudh Chiti +29
We present deep, wide-field Magellan/Megacam imaging of the ultra-faint Milky Way (MW) satellites Grus II (Gru II) and Horologium II (Hor II), with the aim of deriving improved con…
Discovery and Spectroscopic Characterization of a Distant, Compact Milky Way Satellite in Gemini
K. Overdeck, W. Cerny, C. Y. Tan +27
We present the discovery of a compact Milky Way satellite in the constellation of Gemini. This system was discovered by cross-matching detections from two independent search algori…

A. Chiti, A. Drlica-Wagner, A. B. Pace +42
We present the DECam Mapping the Ancient Galaxy in CaHK (MAGIC) survey, a 54-night NOIRLab Survey Program to image 5,000deg of the southern hemisphere using a meta…
A second-generation star in a relic dwarf galaxy
Anirudh Chiti, Vinicius M. Placco, Andrew B. Pace +22
Stars that contain only trace amounts of elements heavier than helium, referred to as having low "metallicity", preserve the chemical fingerprints of the first generation of stars…
