AGN, host galaxies, and starbursts

Proceedings of the International Astronomical Union, 2019
AGN by definition live in galaxies. Despite a long history of studies, there is still much ongoing research into the interplay of the nucleus and the host galaxy, how do they affect each other, how is their evolution intertwined. This review will briefly

AGN Host Galaxies at Intermediate Redshift

, 1997
We analyse the stellar component of nearby Seyfert host galaxies using population and evolution synthesis methods. We propose to study the host galaxy properties of AGNs as a function of redshift with the ESO VLT.

THE HOST GALAXIES OF 23,000 AGN

Multiwavelength AGN Surveys, 2004
We examine the relationship between galaxies, supermassive black holes and AGN using a sample of ~ 2 3 , 0 0 0 narrow-emission-line (Type 2) AGN drawn from a sample of ~ 1 2 3 , 0 0 0 galaxies from the Sloan Digital Sky Survey. We have studied how AGN host properties compare to those of normal galaxies and how they depend on the luminosity of the ...

The coevolution of the AGNs and their host galaxies

2021
Η παρούσα διδακτορική διατριβή, πραγματεύεται τη μελέτη της σχέσης του Eνεργού Γαλαξιακού Πυρήνα (AGN) με τον περιβάλλοντα γαλαξία. Μελέτες των τελευταίων δεκαετιών έχουν οδηγήσει στο συμπέρασμα ότι υπάρχει άρρηκτη σχέση ανάμεσα στους γαλαξίες και στις υπερμεγέθεις μελανές οπές (SMBHs) που φιλοξενούν στο κέντρο τους.
