A halo mass—concentration relation from weak lensing

  title={A halo mass—concentration relation from weak lensing},
  author={Rachel Mandelbaum and Uros Seljak and Christopher M. Hirata},
  journal={Journal of Cosmology and Astroparticle Physics},
We perform a statistical weak lensing analysis of dark matter profiles around tracers of halo mass from galaxy-size to cluster-size halos. In this analysis we use 170 640 isolated ∼L∗ galaxies split into ellipticals and spirals, 38 236 groups traced via isolated spectroscopic luminous red galaxies and 13 823 maxBCG clusters from the Sloan Digital Sky Survey covering a wide range of richness. Together these three samples allow a determination of the density profiles of dark matter halos over… Expand
