Dark energy survey year 3 results: miscentring calibration and X-ray-richness scaling relations in redMaPPer clusters Open
We use Dark Energy Survey Year 3 (DES Y3) clusters with archival XMM–Newton and Chandra X-ray data to assess the centring performance of the redMaPPer cluster finder and to measure key richness observable scaling relations. We find that 10…

Examining the self-interaction of dark matter through central cluster galaxy offsets Open
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 dark matter possesses a non-negligible level of self-interac…

Cool Cores in Clusters of Galaxies in the Dark Energy Survey Open
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 cluster richness. Clusters were selected from the redMaPPer ana…

Velocity dispersions of clusters in the Dark Energy Survey Y3 redMaPPer catalogue Open
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 prob…
