Early-type galaxies in the SDSS. I. The sample
M. Bernardi, R. K. Sheth, J. Annis +7
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. This pa…
Early-type galaxies in the SDSS. IV. Colors and chemical evolution
M. Bernardi, R. K. Sheth, J. Annis +5
The colors and chemical abundances of early-type galaxies at redshifts z<0.3 are studied using a sample of nearly 9000 galaxies, selected from the Sloan Digital Sky Survey using mo…
Spectroscopic Target Selection in the Sloan Digital Sky Survey: The Main Galaxy Sample
Michael A. Strauss, David H. Weinberg, Robert H. Lupton +1
We describe the algorithm that selects the main sample of galaxies for spectroscopy in the Sloan Digital Sky Survey from the photometric data obtained by the imaging survey. Galaxy…
Composite Quasar Spectra From the Sloan Digital Sky Survey
SDSS Collaboration, Daniel E. Vanden Berk
We have created a variety of composite quasar spectra using a homogeneous data set of over 2200 spectra from the Sloan Digital Sky Survey (SDSS). The quasar sample spans a redshift…
Redshift-Distance Survey of Early-Type Galaxies. IV. Dipoles of the Velocity Field
L. N. da Costa, M. Bernardi, M. V. Alonso +5
We use the recently completed redshift-distance survey of nearby early-type galaxies (ENEAR) to measure the dipole component of the peculiar velocity field to a depth of cz ~ 6000…
