Description:
Out of the many individual cases of clusters with spectral complexity reported in the literature, attention is given to the spectral complexity of the most recent data obtained by the Einstein Observatory and an attempt is made to explain at least a portion of the data in terms of models of radiatively-regulated accretion in the central parts of the clusters and/or onto massive galaxies. After a review of the range of models proposed, with emphasis on predicted temperature distribution, it is noted that all accretion models have temperatures which decrease toward the center, and that several authors have explored the consequences of radiative cooling of the gas in the dense central regions of a cluster or of a cluster plus a central galaxy.
