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…

The chemical abundance pattern of the extremely metal-poor thin disk star 2MASS J1808-5104 and its origins

Mohammad K. Mardini, Anna Frebel, Rana Ezzeddine +6

We present a high-resolution (), high signal-to-noise () Magellan/MIKE spectrum of the bright extremely metal-poor star 2MASS~J18085104. We find [Fe/H] = $…

The Atari Disk, a Metal-Poor Stellar Population in the Disk System of the Milky Way

Mohammad K. Mardini, Anna Frebel, Anirudh Chiti +3

We have developed a chemo-dynamical approach to assign 36,010 metal-poor SkyMapper stars to various Galactic stellar populations. Using two independent techniques (velocity and act…

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…

Tucana B: A Potentially Isolated and Quenched Ultra-faint Dwarf Galaxy at D1.4 Mpc

D. J. Sand, B. Mutlu-Pakdil, M. G. Jones +7

We report the discovery of Tucana B, an isolated ultra-faint dwarf galaxy at a distance of D=1.4 Mpc. Tucana B was found during a search for ultra-faint satellite companions to the…

Detailed chemical abundances of stars in the outskirts of the Tucana II ultra-faint dwarf galaxy

Anirudh Chiti, Anna Frebel, Alexander P. Ji +6

We present chemical abundances and velocities of five stars between 0.3 kpc to 1.1 kpc from the center of the Tucana II ultra-faint dwarf galaxy (UFD) from high-resolution Magellan…
