The multiple quasar Q2237+0305 under a microlensing caustic
T. Anguita, R. W. Schmidt, E. L. Turner +5
We use the high magnification event seen in the 1999 OGLE campaign light curve of image C of the quadruply imaged gravitational lens Q2237+0305 to study the structure of the quasar…
The UV Properties of SDSS Selected Quasars
George B. Trammell, Daniel E. Vanden Berk, Donald P. Schneider +4
We present an analysis of the broadband UV/optical properties of z<3.4 quasars matched in the Galaxy Evolution Explorer (GALEX) General Data Release 1 (GR1) and the Sloan Digital S…
Observational constraints on the evolutionary connection between PG 1159 stars and DO white dwarfs
S. D. Huegelmeyer, S. Dreizler, K. Werner +3
The Sloan Digital Sky Survey has provided spectra of a large number of new PG 1159 stars and DO white dwarfs. This increase in known hot H-deficient compact objects significantly i…
Spectral analyses of 16 DAO white dwarfs from the Sloan Digital Sky Survey
S. D. Huegelmeyer, S. Dreizler, T. Rauch +1
We present a spectral analysis of 16 DAO white dwarfs from the Sloan Digital Sky Survey Data Release 4. With our NLTE H+He model grid, we derived photospheric parameters for these…
A Time Delay for the Largest Gravitationally Lensed Quasar: SDSS J1004+4112
J. Fohlmeister, C. S. Kochanek, E. E. Falco +12
We present 426 epochs of optical monitoring data spanning 1000 days from December 2003 to June 2006 for the gravitationally lensed quasar SDSS J1004+4112. The time delay between th…
The Origin of the Bifurcation in the Sagittarius Stream
M. Fellhauer, V. Belokurov, N. W. Evans +9
The latest Sloan Digital Sky Survey data reveal a prominent bifurcation in the distribution of debris of the Sagittarius dwarf spheroidal (Sgr) beginning at a right ascension of ro…
