ISO far-infrared observations of rich galaxy clusters III. Abell 2029, Abell 2052, Abell 2142

A sample of five rich galaxy clusters has been mapped by ISO at 60 mum, 100 mum, 135 mum, and 200 mum using the PHT-C camera. In previous papers Abell 2670 and Sersic 159-03 were discussed. Here we present the results for Abe ll 2029, Abell 2052, and Abell 2142. The conclusion of the survey is that t he relatively small fields (approximate to 60 square are minutes) are struc tured with filaments or superpositions of point sources. In some cases poin t sources (approximate to 0.1 Jy) can be identified with cluster galaxies. An attempt to demonstrate infrared emission from dust in the cooling flows (due to star formation) was inconclusive.
