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…
