We have used the Sloan Digital Sky Survey (SDSS) to undertake an investigation of lopsidedness in a sample of ~25,000 nearby galaxies (z < 0.06). We use the m=1 azimuthal Fourier mode between the 50%...

The Lopsidedness of Present-Day Galaxies: Results from the Sloan Digital Sky Survey (2007)
Reichard, Timothy A., Heckman, Timothy M., Rudnick, Gregory, Brinchmann, Jarle, Kauffmann, Guinevere
Large-scale asymmetries in the stellar mass distribution in galaxies are believed to trace non-equilibrium situations in the luminous and/or dark matter component. These may arise in the aftermath of...
Trump, Jonathan R., Hall, Patrick B., Reichard, Timothy A., Richards, Gordon T., Schneider, Donald P., Berk, Daniel E. Vanden, ...
We present a total of 4784 unique broad absorption line quasars from the Sloan Digital Sky Survey Third Data Release. An automated algorithm was used to match a continuum to each quasar and to...
Constraints on Quasar Continuum, BELR, and BALR Physics from SDSS Composite Spectra (2003)
Richards, Gordon T., Hall, Patrick B., Reichard, Timothy A., Berk, Daniel E. Vanden, Schneider, Donald P., Strauss, Michael A.
We review recent results on quasars from the SDSS as they relate to our understanding of the UV/optical continuum, the broad emission line region, and the broad absorption line region. The ensemble...
Continuum and Emission-Line Properties of Broad Absorption Line Quasars (2003)
Reichard, Timothy A., Richards, Gordon T., Hall, Patrick B., Schneider, Donald P., Berk, Daniel E. Vanden, Fan, Xiaohui, ...
We investigate the continuum and emission-line properties of 224 broad absorption line quasars (BALQSOs) with 0.9
Red and Reddened Quasars in the Sloan Digital Sky Survey (2003)
Richards, Gordon T., Hall, Patrick B., Berk, Daniel E. Vanden, Strauss, Michael A., Schneider, Donald P., Weinstein, Michael A., ...
We investigate the continuum and emission line properties of 4576 SDSS quasars as a function of their optical/UV SEDs. The optical/UV color distribution of our sample is roughly Gaussian, but with a...
Reichard, Timothy A., Richards, Gordon T., Schneider, Donald P., Hall, Patrick B., Tolea, Alin, Krolik, Julian H., ...
We present a catalog of 224 broad absorption line quasars (BALQSOs) from the Sloan Digital Sky Survey's Early Data Release Quasar Catalog, including a relatively complete and homogeneous subsample of...
Broad Emission Line Shifts in Quasars: An Orientation Measure for Radio-Quiet Quasars? (2002)
Richards, Gordon T., Berk, Daniel E. Vanden, Reichard, Timothy A., Hall, Patrick B., Schneider, Donald P., SubbaRao, Mark, ...
Using a sample of 3814 quasars from the Sloan Digital Sky Survey, we confirm that high-ionization, broad, emission lines such as CIV are significantly blueshifted with respect to low-ionization,...
The Sloan Digital Sky Survey Quasar Catalog. I. Early data release (2002)
Schneider, Donald P., Richards, Gordon T., Fan, Xiaohui, Hall, Patrick B., Strauss, Michael A., Vanden Berk, Daniel E., ...
We present the first edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog consists of the 3814 objects ( 3000 discovered by the SDSS) in the initial SDSS public data release...
