Counts of Low-redshift SDSS Quasar Candidates
Z. Ivezic, R. H. Lupton, D. E. Johnston +10
We analyze the counts of low-redshift quasar candidates selected using nine-epoch SDSS imaging data. The co-added catalogs are more than 1 mag deeper than single-epoch SDSS data, a…

Early-type galaxies in the SDSS
M. Bernardi, R. K. Sheth, J. Annis +28
A sample of nearly 9000 early-type galaxies, in the redshift range 0.01<z<0.3, was selected from the Sloan Digital Sky Survey using morphological and spectral criteria. The sample…
