The hosts of AGN and their environments
 

Summary: Lecture 3
The hosts of AGN
and their environments
· Evidence for stars in nuclear and circumnuclear
regions of AGN
· Chemical abundances
· Host galaxies and their environments
· Connection between BH mass and galaxy mass
· AGN and galaxy formation and evolution

Low-z QSOs: host properties
RG
RL QSO RQ QSO
(Mc Lure et al. 1999)
RG fit
(Dunlop et al. 1993)
If low-L AGN have a dichotomy between RL and RQ AGN host galaxies:
RQ tend to reside in early-type S gals
RL tend to reside in E gals
while SBs tend to reside in late-type S gals (e.g. Heckman 1985)
