Present and Future Astrometric Study of Halo Substructure
Steven R. Majewski, Allyson A. Polak, David R. Law +1
We focus on how astrometric surveys might be exploited for the study of Galactic halo substructure originating from the disruption of satellite systems. The Sagittarius (Sgr) dwarf…
Discovery of an extended halo of metal-poor stars in the Andromeda spiral galaxy
Puragra Guhathakurta, James C. Ostheimer, Karoline M. Gilbert +5
Understanding galaxy formation involves look-back and fossil-record studies of distant and nearby galaxies, respectively. Debris trails in our Galaxy's spheroidal halo of old stars…
Star Clusters in the Galactic Anticenter Stellar Structure: New Radial Velocities & Metallicities
Peter M. Frinchaboy, Ricardo R. Munoz, Steven R. Majewski +3
The Galactic Anticenter Stellar Structure (GASS) has been identified with excess surface densities of field stars in several large area sky surveys, and with an unusual, string-lik…
Dark Matter Constraints from the Sagittarius Dwarf and Tail System
Steven R. Majewski, David R. Law, Kathryn V. Johnston +2
2MASS has provided a three-dimensional map of the >360 degree, wrapped tidal tails of the Sagittarius (Sgr) dwarf spheroidal galaxy, as traced by M giant stars. With the inclusion…
The Galactic Anticenter Stellar Stream
Helio J. Rocha-Pinto, Steven R. Majewski, M. F. Skrutskie +1
The recently discovered, ring-like structure just outside the Galactic disk in Monoceros is detected and traced among 2MASS M giant stars. We have developed a method to recover the…
A Large Proper-Motion Survey in Plaut's Low-Extinction Window
R. A. Mendez, R. M. Rich, W. F van Altena +3
We present preliminary results from the deepest and largest photographic proper-motion survey ever undertaken of the Galactic bulge. Our first-epoch plate material (from 1972-3) go…
