Probing the galaxy-halo connection with total satellite luminosity
Jeremy L. Tinker, Junzhi Cao, Mehmet Alpaslan +3
We demonstrate how the total luminosity in satellite galaxies is a powerful probe of dark matter halos around central galaxies. The method cross-correlates central galaxies in spec…

Jun-zhi Cao, Jeremy L. Tinker, Yao-Yuan Mao +1
We develop and implement two new methods for constraining the scatter in the relationship between galaxies and dark matter halos. These new techniques are sensitive to the scatter…
