Measuring Cosmological Distances Using Cluster Edges as a Standard Ruler
Erika L. Wagoner, Eduardo Rozo, Han Aung +1
The line-of-sight velocity dispersion profile of galaxy clusters exhibits a "kink" corresponding to the spatial extent of orbiting galaxies. Because the spatial extent of a cluster…

Linear Systematics Mitigation in Galaxy Clustering in the Dark Energy Survey Year 1 Data
Erika L. Wagoner, Eduardo Rozo, Xiao Fang +3
We implement a linear model for mitigating the effect of observing conditions and other sources of contamination in galaxy clustering analyses. Our treatment improves upon the fidu…

Clusters Have Edges: The Projected Phase SpaceStructure of SDSS redMaPPer Clusters
Paxton Tomooka, Eduardo Rozo, Erika L. Wagoner +3
We study the distribution of line-of-sight velocities of galaxies in the vicinity of SDSS redMaPPer galaxy clusters. Based on their velocities, galaxies can be split into two categ…
