Cool Cores in Clusters of Galaxies in the Dark Energy Survey
K. Graham, J. O'Donnell, M. M. Silverstein +54
We search for the presence of cool cores in optically-selected galaxy clusters from the Dark Energy Survey (DES) and investigate their prevalence as a function of redshift and clus…
Examining the Self-Interaction of Dark Matter through Central Cluster Galaxy Offsets
Dane Cross, Gray Thoron, Tesla Jeltema +7
While collisionless cold dark matter models have been largely successful in explaining a wide range of observational data, some tensions still exist, and it remains possible that d…
Confronting the Chaplygin gas with data: background and perturbed cosmic dynamics
Shambel Sahlu, Heba Sami, Renier Hough +3
In this paper, we undertake a unified study of background dynamics and cosmological perturbations in the presence of the Chaplygin gas. This is done by first constraining the backg…
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…
Perturbations in a Chaplygin gas Cosmology
Shambel Sahlu, Heba Sami, Anna-Mia Swart +3
In this paper we study the perturbations of a cosmic multi-fluid medium consisting of radiation, dust and a Chaplygin gas. To do so, we follow the 1 + 3 covariant formalism and der…
