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…
A MegaCam Survey of Outer Halo Satellites. I. Description of the Survey
Ricardo R. Munoz, Patrick Cote, Felipe A. Santana +5
We describe a deep, systematic imaging study of satellites in the outer halo of the Milky Way. Our sample consists of 58 stellar overdensities --- i.e., substructures classified as…
A survey for dwarf galaxy remnants around fourteen globular clusters in the outer halo
A. Sollima, D. Martinez-Delgado, R. R. Munoz +6
We report the results of a systematic photometric survey of the peripheral regions of a sample of fourteen globular clusters in the outer halo of the Milky Way at distances d_GC>25…
Target Selection for the SDSS-IV APOGEE-2 Survey
G. Zasowski, R. E. Cohen, S. D. Chojnowski +34
APOGEE-2 is a high-resolution, near-infrared spectroscopic survey observing roughly 300,000 stars across the entire sky. It is the successor to APOGEE and is part of the Sloan Digi…
