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…
Reading Between the (Spectral) Lines: Magellan/IMACS spectroscopy of the Ultra-faint Dwarf Galaxies Eridanus IV and Centaurus I
M. E. Heiger, T. S. Li, A. B. Pace +17
We present a spectroscopic analysis of Eridanus IV (Eri IV) and Centaurus I (Cen I), two ultra-faint dwarf galaxies of the Milky Way. Using IMACS/Magellan spectroscopy, we identify…
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…
The Merian Survey: Design, Construction, and Characterization of a Filter Set Optimized to Find Dwarf Galaxies and Measure their Dark Matter Halo Properties with Weak Lensing
Yifei Luo, Alexie Leauthaud, Jenny Greene +28
The Merian survey is mapping 850 degrees of the Hyper Suprime-Cam Strategic Survey Program (HSC-SSP) wide layer with two medium-band filters on the 4-meter Victor M. Bla…
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…
A revisited study of Cepheids in open clusters in the Gaia era
Gustavo E. Medina, Bertrand Lemasle, Eva K. Grebel
In this paper we revisit the problem of identifying bona fide cluster Cepheids by performing an all-sky search for Cepheids associated with open clusters and making use of state-of…
A systematic DECam search for RR Lyrae in the outer halo of the Milky Way
Gustavo E. Medina, Ricardo R. Muñoz, Jeffrey L. Carlin +3
The discovery of very distant stars in the halo of the Milky Way provides valuable tracers on the Milky Way mass and its formation. Beyond 100 kpc from the Galactic center, most of…
Discovery of distant RR Lyrae stars in the Milky Way using DECam
Gustavo Medina, Ricardo Muñoz, Katherina Vivas +9
We report the discovery of distant RR Lyrae stars, including the most distant known in the Milky Way, using data taken in the band with the Dark Energy Camera as part of the Hi…
Serendipitous discovery of RR Lyrae stars in the Leo V ultra-faint galaxy
Gustavo E. Medina, Ricardo R. Muñoz, A. Katherina Vivas +9
During the analysis of RR Lyrae stars discovered in the High cadence Transient Survey (HiTS) taken with the Dark Energy Camera at the 4-m telescope at Cerro Tololo Inter-American O…
SMASH - Survey of the MAgellanic Stellar History
David L. Nidever, Knut Olsen, Alistair R. Walker +36
The Large and Small Magellanic Clouds (LMC and SMC) are unique local laboratories for studying the formation and evolution of small galaxies in exquisite detail. The Survey of the…
