Abstract

A sample of five rich galaxy clusters has been mapped by ISO at , , , and using the PHT-C camera. In previous papers Abell 2670 and Sérsic 159-03 were discussed. Here we present the results for Abell 2029, Abell 2052, and Abell 2142. The conclusion of the survey is that the relatively small fields (60 square arc minutes) are structured with filaments or superpositions of point sources. In some cases point sources ( 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.

Key words: galaxies: clusters: individual: Abell 2029, Abell 2052, Abell 2142 infrared: galaxies
