Current Status of Radio Observations of selected Clusters of Galaxies with the 100-m Telescope Effelsberg

Abstract

We present the current status of radio observations of several clusters of galaxies done with the 100-m telescope Effelsberg. The purpose of this still ongoing project is to obtain new sensitive single-dish measurements of large extended diffuse radio sources in these clusters. The use of a single-dish is required to recover all the flux. In this paper we present the current maps of the clusters Coma, Abell 2256 and Abell 2163.
