Validation of Selection Function, Sample Contamination and Mass Calibration in Galaxy Cluster Samples
S. Grandis, M. Klein, J. J. Mohr +70
We construct and validate the selection function of the MARD-Y3 sample. This sample was selected through optical follow-up of the 2nd ROSAT faint source catalog (2RXS) with Dark En…

A New RASS Galaxy Cluster Catalog with Low Contamination Extending to in the DES Overlap Region
Matthias Klein, Sebastian Grandis, Joseph Mohr +2
We present the MARD-Y3 catalog of between 1086 and 2171 galaxy clusters (52\% and 65\% new) produced using multi-component matched filter (MCMF) followup in 5000\,deg of DES-Y3…

Impact of Weak Lensing Mass Calibration on eROSITA Galaxy Cluster Cosmological Studies -- a Forecast
Sebastian Grandis, Joseph J. Mohr, Joerg P. Dietrich +5
We forecast the impact of weak lensing (WL) cluster mass calibration on the cosmological constraints from the X-ray selected galaxy cluster counts in the upcoming eROSITA survey. W…
