Mapping the Galactic Halo III. Simulated Observations of Tidal Streams
Paul Harding, Heather L. Morrison, Edward W. Olszewski +5
We have simulated the evolution of tidal debris in the Galactic halo in order to guide our ongoing survey to determine the fraction of halo mass accreted via satellite infall. Cont…
Stars of the Draco Dwarf Spheroidal Galaxy Beyond its Measured Tidal Boundary
Slawomir Piatek, Carlton Pryor, Taft E. Armandroff +1
We report R- and V-band photometry derived from CCD imaging for objects in nine fields in and around the Draco dwarf spheroidal galaxy. The most distant fields are about 1.3 degree…
Mapping the Galactic Halo IV. Finding Distant Giants Reliably with the Washington System
H. L. Morrison, E. W. Olszewski, M. Mateo +4
We critically examine the use of the Washington photometric system (with the 51 filter) for identifying distant halo giants. While this is the most powerful photometric technique f…
Mapping the Galactic Halo II: Photometric Survey
R. C. Dohm-Palmer, Mario Mateo, E. Olszewski +4
We present imaging results from a high Galactic latitude survey designed to examine the structure of the Galactic halo. The objective of the survey is to identify candidate halo st…
Mapping the Galactic Halo I. The `Spaghetti' Survey
Heather L. Morrison, Mario Mateo, Edward W. Olszewski +5
We describe a major survey of the Milky Way halo designed to test for kinematic substructure caused by destruction of accreted satellites. We use the Washington photometric system…
