Lots of conversations with Rachel Somerville (MPIA) and Davé today about the idea that mergers trigger starbursts and AGN, and the AGN shuts off star formation so that the fading remnant galaxy can join the red sequence. This picture is observationally tractable, but it is difficult to robustly constrain the fraction of AGN that are merger-triggered, the fraction of mergers that trigger AGN, and all the relevant timescales. We came up with some ideas for Quintero to test when he arrives here next week.
Why does Quintero always have to do everything?
