ASCA OBSERVATIONS OF COOLING FLOWS IN CLUSTERS OF GALAXIES

ASCA spectra of the central regions of three cooling flows, in the Per seus, Centaurus, and A1795 clusters, together with the spectrum of the center of the Coma Cluster, are studied. Absorbed, cooler and/or cool ing components are required for the cooling flow spectra but not for t hat of the Coma Cluster. Problems have been encountered with the basic plasma emission models in the energy range of the iron L complex, whi ch preclude further detailed analysis at present. Our results show the potential of ASCA data for revealing the structure of cooling flows.
