The case of NGC 5824, a cluster possibly embedded in a dark matter halo
Paula B. Díaz, Berenice Muruaga, Ricardo R. Muñoz +3
The globular cluster NGC 5824 exhibits a diffuse stellar envelope that extends beyond its nominal King tidal radius and symmetrically surrounds the cluster. The origin of these sta…
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…
Chemo-Dynamical Tagging in the Outskirts: The Origins of Stellar Substructures in the Magellanic Clouds
César Muñoz, Antonela Monachesi, David L. Nidever +12
We present the first detailed chemical analysis from APOGEE-2S observations of stars in six regions of recently discovered substructures in the outskirts of the Magellanic Clouds e…
Multiple Populations in Low-mass Globular Clusters: Eridanus
Yue Wang, Baitian Tang, Chengyuan Li +5
Multiple populations (MPs), characterized by variations in light elemental abundances, have been found in stellar clusters in the Milky Way, Magellanic Clouds, as well as several o…
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…
Young, blue, and isolated stellar systems in the Virgo Cluster. I. 2-D Optical spectroscopy
M. Bellazzini, L. Magrini, M. G. Jones +20
We use panoramic optical spectroscopy obtained with MUSE@VLT to investigate the nature of five candidate extremely isolated low-mass star forming regions (Blue Candidates, BCs here…
