Timing the r-Process Enrichment of the Ultra-Faint Dwarf Galaxy Reticulum II
Joshua D. Simon, Thomas M. Brown, Burçin Mutlu-Pakdil +65
The ultra-faint dwarf galaxy Reticulum II (Ret II) exhibits a unique chemical evolution history, with 72 +10/-12% of its stars strongly enhanced in r-process elements. We present d…
: Probing the Milky Way and Magellanic Clouds potentials with the 6-D map of the Orphan-Chenab stream
Sergey E. Koposov, Denis Erkal, Ting S. Li +11
We present a 6-D map of the Orphan-Chenab (OC) stream by combining the data from Southern Stellar Stream Spectroscopic Survey () and {\it Gaia}. We reconstruct the proper moti…
Identification of Galaxy-Galaxy Strong Lens Candidates in the DECam Local Volume Exploration Survey Using Machine Learning
E. A. Zaborowski, A. Drlica-Wagner, F. Ashmead +88
We perform a search for galaxy-galaxy strong lens systems using a convolutional neural network (CNN) applied to imaging data from the first public data release of the DECam Local V…
Six More Ultra-Faint Milky Way Companions Discovered in the DECam Local Volume Exploration Survey
W. Cerny, C. E. Martínez-Vázquez, A. Drlica-Wagner +28
We report the discovery of six ultra-faint Milky Way satellites discovered through matched-filter searches conducted using Dark Energy Camera (DECam) data processed as part of the…
Streams on FIRE: Populations of Detectable Stellar Streams in the Milky Way and FIRE
Nora Shipp, Nondh Panithanpaisal, Lina Necib +18
We present the first detailed study comparing the populations of stellar streams in cosmological simulations to observed Milky Way dwarf galaxy streams. In particular, we compare s…
Magellan/IMACS spectroscopy of Grus I: A low metallicity ultra-faint dwarf galaxy
Anirudh Chiti, Joshua D. Simon, Anna Frebel +3
We present a chemodynamical study of the Grus I ultra-faint dwarf galaxy (UFD) from medium-resolution () Magellan/IMACS spectra of its individual member stars. We iden…
