Probing Spectroscopic Variability of Galaxies & Narrow-Line Active Galactic Nuclei in the Sloan Digital Sky Survey
Ching-Wa Yip, Andrew Connolly, Daniel Vanden Berk +10
Under the unified model for active galactic nuclei (AGNs), narrow-line (Type 2) AGNs are, in fact, broad-line (Type 1) AGNs but each with a heavily obscured accretion disk. We woul…

This paper describes the Fifth Data Release (DR5) of the Sloan Digital Sky Survey (SDSS). DR5 includes all survey quality data taken through June 2005 and represents the completion…
Redshifts of the Long Gamma-Ray Bursts
Z. Bagoly, I. Csabai, A. Meszaros +4
The low energy spectra of some gamma-ray bursts' show excess components beside the power-law dependence. The consequences of such a feature allows to estimate the gamma photometric…

Donald P. Schneider, Patrick B. Hall, Gordon T. Richards +41
We present the fourth edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog contains 77,429 objects; this is an increase of over 30,000 entries since the previ…
Cosmological Constraints from the SDSS Luminous Red Galaxies
M Tegmark, D Eisenstein, M Strauss +64
We measure the large-scale real-space power spectrum P(k) using luminous red galaxies (LRGs) in the Sloan Digital Sky Survey (SDSS) and use this measurement to sharpen constraints…
New perspectives on strong z=0.5 MgII absorbers: are halo-mass and equivalent width anti-correlated?
Nicolas Bouche, Michael T. Murphy, Celine Peroux +2
We measure the mean halo-mass of z=0.5 MgII absorbers using the cross-correlation (over co-moving scales 0.05-13h^{-1}Mpc) between 1806 MgII quasar absorption systems and ~250,000…
The Rest-frame Optical Colors of 99,000 SDSS Galaxies
V. Smolcic, Z. Ivezic, M. Gacesa +17
We synthesize the rest-frame Stroemgren colors using SDSS spectra for 99,088 galaxies selected from Data Release 1. This narrow-band ~200 AA photometric system (uz, vz, bz, yz), fi…
The Effect of Large-Scale Structure on the SDSS Galaxy Three-Point Correlation Function
R. C. Nichol, R. K. Sheth, Y. Suto +21
We present measurements of the normalised redshift-space three-point correlation function (Q_z) of galaxies from the Sloan Digital Sky Survey (SDSS) main galaxy sample. We have app…

This paper describes the fourth data release of the Sloan Digital Sky Survey (SDSS), including all survey-quality data taken through June 2004. The data release includes five-band…
The Sloan Digital Sky Survey Quasar Catalog III. Third Data Release
D. P. Schneider, P. B. Hall, G. T. Richards +50
We present the third edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog consists of the 46,420 objects in the SDSS Third Data Release that have luminosities…
Detection of the Baryon Acoustic Peak in the Large-Scale Correlation Function of SDSS Luminous Red Galaxies
