Local RR Lyrae Stars: native and alien
R. Zinn, X. Chen, A. C. Layden +1
Measurements of [Fe/H] and radial velocity are presented for 89 RR Lyrae (RRL) candidates within 6 kpc of the Sun. After removal of two suspected non-RRL, these stars were added to…
Disentangling the Virgo Overdensity with RR Lyrae stars
A. Katherina Vivas, Robert Zinn, John Farmer +2
We use a combination of spatial distribution and radial velocity to search for halo sub-structures in a sample of 412 RR Lyrae stars (RRLS) that covers a square degrees…
The QUEST-La Silla AGN Variability Survey
Régis Cartier, Paulina Lira, Paolo Coppi +7
We present the characterization and initial results from the QUEST-La Silla AGN variability survey. This is an effort to obtain well sampled optical light curves in extragalactic f…
A Search for Intergalactic Globular Clusters in the Local Group
Graziella di Tullio Zinn, Robert Zinn
The whole Sloan Digital Sky Survey (SDSS, 14,555 deg^2 has been searched for intergalactic globular clusters (IGCs) in the Local Group (LG). Using optical, infrared, and ultraviole…
Searching for tidal tails around Centauri using RR Lyrae Stars
J. G. Fernández-Trincado, A. K. Vivas, C. E. Mateu +5
We present a survey for RR Lyrae stars in an area of 50 deg around the globular cluster Centauri, aimed to detect debris material from the alleged progenitor galaxy of the…
Metallicity Evolution of the Six Most Luminous M31 Dwarf Satellites
N. Ho, M. Geha, E. Tollerud +3
We present global metallicity properties, metallicity distribution functions (MDFs) and radial metallicity profiles for the six most luminous M31 dwarf galaxy satellites: M32, NGC…
