Long slit spectroscopy of a sample of isolated spirals with and without an AGN
I. Marquez, F. Durret, J. Masegosa +6
We present the kinematical data obtained for a sample of active (Seyfert) and non active isolated spiral galaxies, based on long slit spectra along several position angles in the H…
The detection of stellar velocity dispersion drops in the central regions of five isolated Seyfert spirals
I. Marquez, J. Masegosa, F. Durret +5
We analyze the kinematics of the central regions of five isolated Seyfert spiral galaxies from the DEGAS sample (four with new data presented in this paper, IC184, UGC3223, NGC2639…
A study of dark matter halos and gas properties in clusters of galaxies from ROSAT data
R. Demarco, F. Magnard, F. Durret +1
Self-gravitating systems such as elliptical galaxies appear to have a constant integrated specific entropy and obey a scaling law relating their potential energy to their mass. The…
An XMM-Newton view of the extended "filament" near the cluster of galaxies Abell 85
F. Durret, G. B. Lima Neto, W. Forman +1
We have observed with XMM-Newton the extended 4 Mpc filament detected by the ROSAT PSPC in the neighbourhood of the cluster of galaxies Abell 85. We confirm that there is an extend…
A High Angular Resolution View of Hot Gas in Clusters, Groups, and Galaxies
W. Forman, E. Churazov, L. David +6
We discuss two themes from Chandra and XMM-Newton observations of galaxies, groups, and clusters. First, we review observational aspects of cluster formation and evolution as matte…
