Abstract (from CDS):

We use the shear catalogue from the CFHT Stripe-82 Survey to measure the subhalo masses of satellite galaxies in redMaPPer clusters. Assuming a Chabrier initial mass function and a truncated NFW model for the subhalo mass distribution, we find that the subhalo mass to galaxy stellar mass ratio increases as a function of projected halo-centric radius rp, from at rp ∈ [0.1, 0.3] h–1 Mpc to at rp ∈ [0.6, 0.9] h–1 Mpc. We also investigate the dependence of subhalo masses on stellar mass by splitting satellite galaxies into two stellar mass bins: 10 Mstar/h–1 M☉) Mstar/h–1 M☉) () versus ().
