Velocity Dispersions of Clusters in the Dark Energy Survey Y3 redMaPPer Catalog

V. Wetzell, T. E. Jeltema, B. Hegland +96

We measure the velocity dispersions of clusters of galaxies selected by the redMaPPer algorithm in the first three years of data from the Dark Energy Survey (DES), allowing us to p…

The XMM Cluster Survey: Testing chameleon gravity using the profiles of clusters

Harry Wilcox, David Bacon, Robert C. Nichol +17

The chameleon gravity model postulates the existence of a scalar field that couples with matter to mediate a fifth force. If it exists, this fifth force would influence the hot X-r…
