A FIRST GLIMPSE INTO ISM ICM CONNECTIONS AT Z=0.2 WITH ISOCAM/

Although it is well established that the cluster environment affects t he gas content and massive star formation in galaxies, the mechanisms have not yet been unambiguously identified. In order to elucidate some of the processes responsible, an ISO Core Programme-DEEPXSRC-is dedic ated to deep observations of medium redshift rich clusters of galaxies . We present here the first results from this programme, obtained by c orrelating our ISOCAM observations (at 7.5 and 15 mu m) of the cluster A1732 with radio, optical and X-ray images. Some 10 distant IR galaxi es are detected in an 8'x8' field and are the faintest extragalactic s ources detected by ISO so far.
