New Luminous Blue Variables in the Andromeda galaxy
O. Sholukhova, D. Bizyaev, S. Fabrika +3
We performed spectroscopy of five Luminous Blue Variable (LBV) candidates and two known LBV stars (AE And and Var A-1) in M31. We obtained the same-epoch near-infrared (NIR) and op…
Chandra X-Ray Observations of Two Unusual BAL Quasars
Jesse A. Rogerson, Patrick B. Hall, Stephanie A. Snedden +2
We report sensitive Chandra X-ray non-detections of two unusual, luminous Iron Low-Ionization Broad Absorption Line Quasars (FeLoBALs). The observations do detect a non-BAL, wide-b…
Discovery of two new accreting pulsating white dwarf stars
Anjum S. Mukadam, B. T. Gänsicke, P. Szkody +4
We report the discovery of two new accreting pulsating white dwarf stars amongst the cataclysmic variables of the Sloan Digital Sky Survey: SDSSJ074531.91+453829.5 and SDSSJ091945.…
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…
Hubble Space Telescope Ultraviolet Spectroscopy of Fourteen Low-Redshift Quasars
Rajib Ganguly, Michael S. Brotherton, Nahum Arav +35
We present low-resolution ultraviolet spectra of 14 low redshift (z<0.8) quasars observed with HST/STIS as part of a Snap project to understand the relationship between quasar outf…
The 2dF-SDSS LRG and QSO survey: Evolution of the Luminosity Function of Luminous Red Galaxies to z=0.6
D. A. Wake, R. C. Nichol, D. J. Eisenstein +23
We present new measurements of the luminosity function (LF) of Luminous Red Galaxies (LRGs) from the Sloan Digital Sky Survey (SDSS) and the 2dF-SDSS LRG and Quasar (2SLAQ) survey.…
