Serendipitous XMM-Newton discovery of a cluster of galaxies at z=0.28
Fabio Gastaldello, David A. Buote, Philip J. Humphrey +5
We report the discovery of a galaxy cluster serendipitously detected as an extended X-ray source in an offset observation of the group NGC 5044. The cluster redshift, z=0.281, dete…
Far Infrared Emission from Elliptical Galaxies: NGC 4649, NGC 4472, and NGC 4636
P. Temi, W. G. Mathews, F. Brighenti +1
We present ISOPHOT P32 oversampled maps and P37/39 sparse maps, of three bright elliptical galaxies in the Virgo Cluster. The maps reach the limiting sensitivity of the ISOPHOT ins…
Heating of Gas in Galaxy Groups and Clusters
Fabrizio Brighenti, William G. Mathews
Was the diffuse gas in galaxy groups and clusters heated at high redshift before it entered a massive halo, or was the heating produced inside collapsed objects by SNII accompanyin…
Evolution of Gas in Elliptical Galaxies
William G. Mathews, Fabrizio Brighenti
We review the origin and structure of hot (cooling flow) gas in elliptical galaxies. X-ray observations can be used to determine the stellar mass to light ratio, the mass profiles…
Hot Gas and Halos in Elliptical Galaxies
William G. Mathews, Fabrizio Brighenti
We review recent progress in understanding the evolution of hot interstellar gas in the halos of elliptical galaxies. Non-homologous variations in the physical size of the hot gas…
Galactic Drips and How to Stop Them!
William G. Mathews
The temperature of hot interstellar gas at large radii in elliptical galaxies can be lower than the mean galactic virial temperature. If so, a nonlinear cooling wave can form in th…
