Journal ArticleDOI
The nature and space density of fossil groups of galaxies
TL;DR: In this article, the properties of a sample of galaxy groups with very unusual distributions of galaxy luminosities were described, and a small X-ray-selected, flux-limited sample of fossil groups with well-known selection criteria was constructed.

TL;DR: The Deep X-Ray Radio Blazar Survey (DXRBS) as discussed by the authors is a survey of flat-spectrum radio-loud quasars (FSRQs) and BL Lacertae objects.

TL;DR: In this article, a survey of archived, pointed ROSAT PSPC data for blazars by correlating the ROSAT WGACAT database with several publicly available radio catalogs, restricting our candidate list to serendipitous flat radio spectrum sources (alpha_r <= 0.70).

TL;DR: The XMM Large Scale Structure Survey with XMM (XMM-LSS) as mentioned in this paper is a large-scale X-ray survey with the aim of studying the correlation function and the cluster number density.
