The Effects of the Sagittarius Dwarf Tidal Stream on Dark Matter Detectors
Katherine Freese, Paolo Gondolo, Heidi Jo Newberg +1
The Sagittarius dwarf tidal stream may be showering dark matter onto the solar neighborhood, which can change the results and interpretation of WIMP direct detection experiments. S…
Sagittarius Tidal Debris 90 kpc from the Galactic Center
Heidi Jo Newberg, Brian Yanny, Eva K. Grebel +9
A new overdensity of A-colored stars in distant parts of the Milky Way's stellar halo, at a dereddened SDSS magnitude of g_0 = 20.3, is presented. Identification of associated vari…
Detectability of Weakly Interacting Massive Particles in the Sagittarius Dwarf Tidal Stream
Katherine Freese, Paolo Gondolo, Heidi Jo Newberg
Tidal streams of the Sagittarius dwarf spheroidal galaxy (Sgr) may be showering dark matter onto the solar system and contributing approx (0.3--23)% of the local density of our Gal…
The Sloan Digital Sky Survey Quasar Catalog II. First Data Release
Donald P. Schneider, Xiaohui Fan, Patrick B. Hall +13
We present the second edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog consists of 16713 objects in the SDSS First Data Release (DR1) that have luminositi…
The extended tails of Palomar 5: A ten degree arc of globular cluster tidal debris
M. Odenkirchen, E. K. Grebel, W. Dehnen +7
Using wide-field photometric data from the Sloan Digital Sky Survey (SDSS) we recently showed that the Galactic globular cluster Palomar 5 is in the process of being tidally disrup…
The First Data Release of the Sloan Digital Sky Survey
The SDSS collaboration, Kevork Abazajian
The Sloan Digital Sky Survey has validated and made publicly available its First Data Release. This consists of 2099 square degrees of five-band (u, g, r, i, z) imaging data, 186,2…
A Large, Uniform Sample of X-ray Emitting AGN: Selection Approach and an Initial Catalog from the ROSAT All-Sky and Sloan Digital Sky Surveys
Scott F. Anderson, Wolfgang Voges, Bruce Margon +25
Many open questions in X-ray astronomy are limited by the relatively small number of objects in uniform optically-identified samples, especially when rare subclasses are considered…
New Resources to Explore the Old Galaxy: Mining the SDSS
C. Allende Prieto, T. C. Beers, Y. Li +3
The Sloan Digital Sky Survey (SDSS) is collecting photometry and intermediate resolution spectra for ~ 10**5 stars in the thick-disk and stellar halo of the Milky Way. This massive…
SDSS Catalog of Stars in the Draco Dwarf Spheroidal Galaxy
Heather A. Rave, Chongshan Zhao, Heidi Jo Newberg +4
The Sloan Digital Sky Survey (SDSS) has scanned the entire region containing the Draco dwarf spheroidal galaxy to 23rd magnitude in g*. We present a catalog of stars found in a 453…
The Extended Tidal Tails of Palomar 5: Tracers of the Galactic Potential
Michael Odenkirchen, Eva K. Grebel, Hans-Walter Rix +4
We detected extended, curved stellar tidal tails emanating from the sparse, disrupting halo globular cluster Pal 5, which cover 10 degrees on the sky. These streams allow us to inf…
A Low Latitude Halo Stream around the Milky Way
Brian Yanny, Heidi Jo Newberg, Eva K. Grebel +11
We present evidence for a ring of stars in the plane of the Milky Way, extending at least from l = 180 deg to l = 227 deg with turnoff magnitude ; the ring could encir…
