clustocentric morphologies

Quintero and I (read: Quintero) produced this plot today:

(Click to enlarge.) The galaxies shown are randomly selected galaxies in bins of clustocentric distance (scaled by virial radius) and color; the images have been rotated such that the (large) cluster that each galaxy is near is to the left. As I see it, one of these galaxies has a badly measured color (SDSS problem), and one is strongly asymmetric in a way that is likely related to the cluster. Most of the galaxies show no strong sign of the nearby cluster. Note that galaxies at 0 to 0.3 on the horizontal axis are likely falling in to the cluster now.

  1. What are these clusters? Are they
    randomly drawn from Andreas' objects?

  2. Erin: The galaxies are randomly drawn from the regions around extremely rich (Coma-like) clusters in the Berlind catalog; it is the highest richness bin in Quintero et al's clustocentric distance paper.
