Abstract:
We describe the aim and the capabilities of the SZ Cosmological Projects (SZCP) which is bound to construct a sample of 30 nearby clusters with measured values of Comptonization parameter. We present the preliminary results on the detection of an SZ e ect in Coma obtained, within the SZCP, at three frequencies (148, 219 and 269 GHz) and we brie y discuss its cosmological and astrophysical relevance.
