Activity in colliding galaxies
Astrophysics and Space Science, 1993A substantial body of evidence now exists that indicates that there is a connection between the observed activity in galaxies and the apparent involvement of these active galaxies in tidal interactions with other galaxies. To investigate this phenomenon, we are studying the morphologies and environments of various interacting galaxies showing evidence ...

The Fueling of Active Galaxies
The International Journal of Supercomputing Applications, 1991Collisions of galaxies are often invoked to explain vio lent phenomena in the universe. The dynamics of in teracting galaxies is intrinsically three-dimensional and involves both gas and stellar dynamics. In general, a computational approach is needed to model galactic collisions. Galaxy encounters are studied using a hy brid N-body/hydrodynamics code,

Astronomische Nachrichten, 2008
AbstractIn this paper I will review, in an unavoidably incomplete and biased way, the main results obtained by XMM‐Newton on Active Galactic Nuclei. I will then highlight the major issues still open in which XMM‐Newton can still give important contributions, expecially if the observing programs will shift in the future towards more long exposures of ...

The Evolution of Active Galaxies in Clusters
Astrophysics and Space Science, 2003The results of deep radio, sub-mm and X-ray observations of samples of high redshift (z∼1) clusters are presented. These reveal significant excesses of active galaxies associated with the clusters at all three wavelengths. The cluster radio source population shows evolution consistent with the (1+z)3 evolution typical of many AGN classes.
