Status of dark flow ?

  1. May 27, 2010 #1
    I was wondering about the status of the dark flow phenomena (net motion of galaxy clusters with respect to the CMB) claimed by Kashlinsky. Is it accepted among cosmologists or are there some skeptics about it ?

    Probably isn't anything. This more recent analysis shows it isn't even a one-sigma detection of an effect:

    The basic problem is that they apparently didn't take into account the anisotropies of the CMB.
