SEMINAR

The role of AGN in a merger-driven galaxy evolution
Dr. Marios Karouzos
Max-Planck-Institut fuer Radioastronomie, Bonn, Germany

In the context of structure formation in the Universe, the relevance of merger events to AGN is still under debate. I investigated the Caltech-Jodrell Bank flat-spectrum sample, a statistically complete sample of radio-loud active galaxies, for evidence supporting a merger-driven evolution for AGN. In this talk, I will present a strong connection between CJF sources in the local Universe (z<0.4) to merger events. I shall also discuss evidence suggesting the importance of a star-formation (thermal) emission component for low luminosity active galaxies. I will also present a classification scheme and use it to classify CJF sources in different evolutionary stages. Finally, I will show preliminary results concerning the close environment of AGN supporting the significance of mergers in their evolution.

The talk will be in English or in Greek, depending on the audience.
