RR Lyrae stars as probes of the outer Galactic halo: Chemical and kinematic analysis of a pilot sample
Gustavo E. Medina, Camilla J. Hansen, Ricardo R. Muñoz +4
We report the spectroscopic analysis of 20 halo ab-type RR Lyrae stars with heliocentric distances between 15 and 165 kpc, conducted using medium-resolution spectra from the Magell…
A search for faint resolved galaxies beyond the Milky Way in DES Year 6: A new faint, diffuse dwarf satellite of NGC 55
M. McNanna, K. Bechtol, S. Mau +63
We report results from a systematic wide-area search for faint dwarf galaxies at heliocentric distances from 0.3 to 2 Mpc using the full six years of data from the Dark Energy Surv…
DELVE 6: An Ancient, Ultra-Faint Star Cluster on the Outskirts of the Magellanic Clouds
W. Cerny, A. Drlica-Wagner, T. S. Li +23
We present the discovery of DELVE 6, an ultra-faint stellar system identified in the second data release of the DECam Local Volume Exploration (DELVE) survey. Based on a maximum-li…
Variable Stars in the giant satellite galaxy Antlia 2
Kathy Vivas, Clara Martínez-Vázquez, Alistair Walker +3
We report 350 pulsating variable stars found in four DECam fields ( sq. deg.) covering the Antlia 2 satellite galaxy. The sample of variables includes 318 RR Lyrae stars a…
The star formation history of Eridanus II: on the role of SNe feedback in the quenching of ultra-faint dwarf galaxies
C. Gallart, M. Monelli, T. Ruiz-Lara +17
Eridanus II (EriII) is an ultra-faint dwarf (UFD) galaxy (M_V=-7.1) located at a distance close to the Milky Way virial radius. Early shallow color-magnitude diagrams (CMD) indicat…
A Deeper Look at DES Dwarf Galaxy Candidates: Grus I and Indus II
Sarah A. Cantu, Andrew B. Pace, Jennifer Marshall +11
We present deep - and -band Magellan/Megacam photometry of two dwarf galaxy candidates discovered in the Dark Energy Survey (DES), Grus I and Indus II (DES J2038-4609). For t…
