As someone who studies galaxies but not AGN specifically (so a semi-outsider) my synthesis of the situation right now is that it seems that there is a relationship between merging and very active (sometimes dust obscured) accretion (e.g., big quasars; from the e.g., PG quasar studies [Bahcall?] or SWIFT studies [Koss et al.]). At lower accretion luminosities (e.g., Seyfert luminosities), most studies (including CANDELS) are finding weak or no evidence for merger enhancement of AGN activity.

But on the last point, I thought that recent observations outside the optical were indicating that maybe it's just dust obscuring AGN in disturbed-looking galaxies.Anonymousnoreply@blogger.com
