merging and the correlation function, XMM

Today, we discussed Morad's results on the correlation function with Milos Milosavljevic (Caltech). Milos said that he has a theoretical result that the inflow of galaxies (subhalos) into clusters (halos) is linear with time, ie, the galaxies flow in at a constant linear velocity. This relatively naturally leads to a 3-space correlation function that goes like r−2.

I gave K+A galaxy targets to Adrienne Juett (Virginia) for an XMM proposal on neutron star binaries (ie, to find binaries with A and later-type stellar companions).
