Abstract:

Resent observations of a number of galaxy clusters using the Sunyaev-Zel'dovich effect indicate that about of the baryonic mass is missing from the hot intracluster medium ( ICM), which is significantly larger than the 1/3 fraction of stars and cool gas, which account for only about 10\%. Here we address the question of whether the remaining can be accounted for by the thermal evaporation of gas from clusters. We have found 22\% +/- 10\% that evaporation can occur only from the cluster ``surface,{''
