Velocity dispersions of clusters in the Dark Energy Survey Y3 redMaPPer catalogue
Velocity dispersions of clusters in the Dark Energy Survey Y3 redMaPPer catalogue
ABSTRACT We measure the velocity dispersions of clusters of galaxies selected by the red-sequence Matched-filter Probabilistic Percolation (redMaPPer) algorithm in the first three years of data from the Dark Energy Survey (DES), allowing us to probe cluster selection and richness estimation, λ, in light of cluster dynamics. Our sample consists …
