Velocity dispersions (top) and distribution along cluster-centric radius (bottom) of four galaxy populations inside MACS1206: blue disks (star forming and n < 2.5), blue spheroids (star forming and n > 2.5), red disks (quiescent and n < 2.5), and red spheroids (quiescent and n > 2.5). Blue disks have large velocity dispersions, which indicates a young, unvirialized population. Velocity dispersion of blue spheroids shows two components, a narrow peak and extended wings. This could be a sign for a mix of virialized and unvirialized, possibly infalling, galaxies. Both red sub-populations have small velocity disperions, and are thus virialized. However, they are found in different locations in the cluster.
