The Sculptor supercluster at z = 0.11 - investigation with ROSAT and the ESO/SERC IIIa-F survey.
Abstract
Optical and X-ray studies of the rich Sculptor supercluster of galaxies (SSC) have been carried out with data from the ESO/SERC IIIa-F survey and ROSAT pointed observations. Limits for the total gravitating mass of the supercluster are determined as 3.2×1016h50-1Msun ≤ MSSC ≤ 1.1×1017h50-1Msun. A search for intra-supercluster gas in the core region of the SSC gave no hints for its existence down to the flux limit LX = 7×10-14erg s-1cm12.
