Active galaxies

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 ...

Activity in colliding galaxies

Astrophysics and Space Science, 1993
A 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 ...

Dusty Active Galaxies

Proceedings of the International Astronomical Union, 2013
AbstractMost astronomers know about B. E. Markarians discovery and further study of galaxies with UV excess. It is less known that in 1963 Markarian drew attention to a small group of galaxies with color index-spectral type discrepancy. Early spectral type of these galaxies is combined with large color index (e.g. M82).
