Why are AGN important
-
-
Self-regulating feedback (Heating from radio jets provides a means to balence cooling of the hot halo gas, stops star formation (maybe)
-
-
HERGS and LERGS
-
LERGS
-
-
-
-
LERG LF's decline strongly, models suggest LERGs density and luminosity evolution following the evolution of massive quiescent galaxies
-
-
What don't we know
-
-
-
-
We can look at how the radio-loudness depends on: mass, star formation, galaxy type, ioniation state, all over cosmic time
-

-
lotss radio loud agn
-
But the distribution of lifetimes is unknown, we see many more small low luminosity sources
Infrared jet powers - forward modelling of analytical RLAGN models and distributions of environments, redshift , lifetimes
-
60% of even the most luminous RLAGN do not have a group/cluster association - substantial proportion of power RLAGN in halos
