The Splashback Feature around DES Galaxy Clusters: Galaxy Density and Weak Lensing Profiles
C. Chang, E. Baxter, B. Jain +82
Splashback refers to the process of matter that is accreting onto a dark matter halo reaching its first orbital apocenter and turning around in its orbit. The cluster-centric radiu…
Density split statistics: Cosmological constraints from counts and lensing in cells in DES Y1 and SDSS data
