J/MNRAS/292/419     Cooling flows in 207 clusters of galaxies    (White+, 1997)

ADC_Keywords: Clusters, galaxy ; X-ray sources Keywords: catalogues - galaxies: clusters: general - cooling flows - galaxies: fundamental parameters - intergalactic medium - X-rays: galaxies Abstract: In this paper we present an X-ray image deprojection analysis of Einstein Observatory imaging data on 207 clusters of galaxies. The resulting radial profiles for luminosity, temperature and electron density variations are determined from the cluster surface-brightness profiles according to gravitational potential constraints from average X-ray temperatures and optical velocity dispersions. This enables us to determine cooling flow and other cluster properties, such as baryon fractions, Sunyaev-Zel'dovich microwave decrements and Thomson depths. From the results we have compiled a catalogue of the detected cooling flows, and investigated their effects on general cluster properties. File Summary:

Note (1): The entries are ordered by decreasing dM/dt (Rank number), and may contain multiple entries for a single cluster if both IPC and HRI data are available, and indicate a cooling flow (then n_Rank = b). Note (2): The occurence of '>' symbol indicates (usually for HRI results) that the outer radius of the deprojection is not large enough that tcool increase above t0, and therefore the numbers are quoted at the radius Rout.
