X-rays from the First Massive Black Holes
W. N. Brandt, C. Vignali, D. P. Schneider +7
X-ray studies of high-redshift (z > 4) active galaxies have advanced substantially over the past few years, largely due to results from the new generation of X-ray observatories. A…
Two Rare Magnetic Cataclysmic Variables with Extreme Cyclotron Features Identified in the Sloan Digital Sky Survey
Paula Szkody, Scott F. Anderson, Gary Schmidt +6
Two newly identified magnetic cataclysmic variables discovered in the Sloan Digital Sky Survey (SDSS), SDSSJ155331.12+551614.5 and SDSSJ132411.57+032050.5, have spectra showing hig…
Faint High Latitude Carbon Stars Discovered by the Sloan Digital Sky Survey: Methods and Initial Results
Bruce Margon, Scott F. Anderson, Hugh C. Harris +5
We report the discovery of 39 Faint High Latitude Carbon Stars (FHLCs) from Sloan Digital Sky Survey commissioning data. The objects, each selected photometrically and verified spe…
The UV Spectrum of the Ultra-compact X-ray Binary- 4U 1627-673
L. Homer, Scott F. Anderson, Stefanie Wachter +1
We have obtained Hubble Space Telescope/STIS low-resolution ultraviolet spectra of the X-ray pulsar 4U 1626-67 (=KZ TrA); 4U 1626-67 is unusual even among X-ray pulsars due to its…
Characterization of M,L and T dwarfs in the Sloan Digital Sky Survey
S. L. Hawley, K. R. Covey, G. R. Knapp +2
An extensive sample of M, L and T dwarfs identified in the Sloan Digital Sky Survey (SDSS) has been compiled. The sample of 718 dwarfs includes 677 new objects (629 M dwarfs, 48 L…
Unusual Broad Absorption Line Quasars from the Sloan Digital Sky Survey
Patrick B. Hall, S. F. Anderson, M. A. Strauss +6
The Sloan Digital Sky Survey has confirmed the existence of populations of broad absorption line (BAL) quasars with various unusual properties. We present and discuss twenty-three…
