The Cluster Mass Function from Early SDSS Data: Cosmological Implications
Neta A. Bahcall, Feng Dong, Paul Bode +15
The mass function of clusters of galaxies is determined from 400 deg^2 of early commissioning imaging data of the Sloan Digital Sky Survey; ~300 clusters in the redshift range z =…
A Merged Catalog of Clusters of Galaxies from Early SDSS Data
Neta A. Bahcall, Timothy A. McKay, James Annis +13
We present a catalog of 799 clusters of galaxies in the redshift range z_est = 0.05 - 0.3 selected from ~400 deg^2 of early SDSS commissioning data along the celestial equator. The…
Constraining the Scatter in the Mass-Richness Relation of maxBCG Clusters With Weak Lensing and X-ray Data
Eduardo Rozo, Eli S. Rykoff, August Evrard +10
We measure the logarithmic scatter in mass at fixed richness for clusters in the maxBCG cluster catalog, an optically selected cluster sample drawn from SDSS imaging data. Our meas…
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…
Composite Luminosity Functions Based on the Sloan Digital Sky Survey "Cut & Enhance" Galaxy Cluster Catalog
Tomotsugu Goto, Sadanori Okamura, Timothy A. Mckay +9
We present here results on the composite luminosity functions of galaxies in the clusters of galaxies selected from the SDSS Cut and Enhance cluster catalog (CE; Goto et al. 2001).…
An Improved Cluster Richness Estimator
Eduardo Rozo, Eli S. Rykoff, Benjamin P. Koester +11
Minimizing the scatter between cluster mass and accessible observables is an important goal for cluster cosmology. In this work, we introduce a new matched filter richness estimato…
