Scientific paper

We present ASCA results of the Sculptor supercluster, a rich supercluster with a redshift of 0.11, near to the south galactic pole. We searched for excess emission associated with the supercluster, and obtained the 3 sigma upper limit as 16% of the brightness of the cosmic X-ray background in the 0.8--10 keV band. The X-ray properties of member clusters were analyzed and compared with other clusters. As for temperature-luminosity relation, no difference between the clusters in this supercluster and other clusters could be found. Applying the beta model, we estimated the gas mass and the total gravitational mass associated with individual clusters, as well as those of the overall supercluster.
