The Morphology-Density Relation in the Sloan Digital Sky Survey
Tomotsugu Goto, Chisato Yamauchi, Yutaka Fujita +5
We have studied the morphology-density relation and morphology--cluster-centric-radius relation using a volume limited sample (0.050.1, 20.5) of the Sloan Digital Sky…
Redshift-Distance Survey of Early-Type Galaxies: Spectroscopic Data
G. Wegner, M. Bernardi, C. N. A. Wilmer +5
We present central velocity dispersions and Mg line indices for an all-sky sample of 1178 elliptical and S0 galaxies, of which 984 had no previous measures. This sample…
SDSS J0903+5028: A New Gravitational Lens
David E. Johnston, Gordon T. Richards, Joshua A. Frieman +22
We report the discovery of a new gravitationally lensed quasar from the Sloan Digital Sky Survey, SDSS J090334.92+502819.2. This object was targeted for SDSS spectroscopy as a Lumi…
The Environment of AGNs in the Sloan Digital Sky Survey
Christopher J. Miller, Robert C. Nichol, Percy Gomez +2
We present the observed fraction of galaxies with an Active Galactic Nucleus (AGN) as a function of environment in the Early Data Release of the Sloan Digital Sky Survey (SDSS). Us…
Stellar and Dynamical Masses of Ellipticals in the Sloan Digital Sky Survey
N. Padmanabhan, U. Seljak, M. A. Strauss +9
We study the variation of the dark matter mass fraction of elliptical galaxies as a function of their luminosity, stellar mass, and size using a sample of 29,469 elliptical galaxie…
Star formation rate indicators in the Sloan Digital Sky Survey
A. M. Hopkins, C. J. Miller, R. C. Nichol +8
The Sloan Digital Sky Survey (SDSS) first data release provides a database of 106000 unique galaxies in the main galaxy sample with measured spectra. A sample of star-forming (SF)…
The First Data Release of the Sloan Digital Sky Survey
The SDSS collaboration, Kevork Abazajian
The Sloan Digital Sky Survey has validated and made publicly available its First Data Release. This consists of 2099 square degrees of five-band (u, g, r, i, z) imaging data, 186,2…
An estimate of Ω_m without priors
Hume A. Feldman, Roman Juszkiewicz, Pedro Ferreira +10
Using mean relative peculiar velocity measurements for pairs of galaxies, we estimate the cosmological density parameter and the amplitude of density fluctuations . Our…
Large Scale Structure in the Sloan Digital Sky Survey
M. Bernardi
The primary observational goals of the Sloan Digital Sky Survey are to obtain CCD imaging of 10,000 deg^2 of the north Galactic cap in five passbands, with a limiting magnitude in…
The velocity dispersion function of early-type galaxies
Ravi K. Sheth, M. Bernardi, P. L. Schechter +12
The distribution of early-type galaxy velocity dispersions, phi(sigma), is measured using a sample drawn from the SDSS database. Its shape differs significantly from that which one…
Early-type galaxies in the SDSS. III. The Fundamental Plane
M. Bernardi, R. K. Sheth, J. Annis +7
A magnitude limited 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…
Hdelta-Selected Galaxies in the Sloan Digital Sky Survey I: The Catalog
Tomotsugu Goto, Robert C. Nichol, Christopher J. Miller +20
[Abridged] We present here a new and homogeneous sample of 3340 galaxies selected from the Sloan Digital Sky Survey (SDSS) based solely on the observed strength of their Hdelta abs…
The Environment of Passive Spiral Galaxies in the SDSS
Tomotsugu Goto, Sadanori Okamura, Maki Sekiguchi +15
In previous work on galaxy clusters, several authors reported a discovery of an unusual population of galaxies, which have spiral morphologies, but do not show any star formation a…
The Morphological Butcher-Oemler effect in the SDSS Cut&Enhance Galaxy Cluster Catalog
Tomotsugu Goto, Sadanori Okamura, Masafumi Yagi +14
We investigate the evolution of the fractions of late type cluster galaxies as a function of redshift, using one of the largest, most uniform cluster samples available. The sample…
