(finally) bearing fruits....
(What I think is) another really nice 2SLAQ paper got posted to astro-ph Monday.
Check out Sadler et al. and quoting the last sentence of the abstract, "the evolution seen in the low-power radio-galaxy population implies that the total energy input into massive early-type galaxies from AGN heating increases with redshift, and was roughly 50% higher at z~0.55 (and up to a factor of two higher at z~1) than in the local universe."
i.e. AGN-galaxy feedback models beware!!
