  • We find that infalling dark matter halos (i.e., the progenitors of satellite halos) begin losing mass well outside the virial radius of their eventual host halos. The peak mass occurs at a range of clustercentric distances, with median and 68th percentile range of for progenitors of z = 0 satellites. The peak circular velocity for infalling halos occurs at significantly larger distances ( at z = 0). This difference arises because different physical processes set peak circular velocity… CONTINUE READING
