A catalog of Nearby Poor Clusters of Galaxies
R. A. White, M. Bliton, S. P. Bhavsar +4
A catalog of 732 optically selected, nearby poor clusters of galaxies covering the entire sky north of declination is presented. The poor clusters, called WBL clus…
Mass and Metallicity of Five X-ray Bright Galaxy Groups
Una Hwang, Richard F. Mushotzky, Jack O. Burns +6
We present ASCA X-ray observations of a sample of five groups selected from a cross-correlation of the ROSAT All-Sky Survey with the White et al. optical catalog of groups. These X…
Redshifts and Optical Properties for a Statistically Complete Sample of Poor Galaxy Clusters
Michael J. Ledlow, Chris Loken, Jack O. Burns +2
From the poor cluster catalog of White et al. (1996), we define a sample of 71 optically-selected poor galaxy clusters. The surface-density enhance- ment we require for our cluster…
The X-ray Luminosity Function and Gas Mass Function for Optically-Selected Poor + Rich Clusters of Galaxies
Jack O. Burns, Michael J. Ledlow, Chris Loken +5
We present the first X-ray Luminosity Function (XLF) for an optically-selected sample of 49 nearby poor clusters of galaxies and a sample of 67 Abell clusters with z < 0.15. We hav…
