Mass Calibration of the CODEX Cluster Sample using SPIDERS Spectroscopy -- I. The Richness-Mass Relation
R. Capasso, J. J. Mohr, A. Saro +9
We use galaxy dynamical information to calibrate the richness-mass scaling relation of a sample of 428 galaxy clusters that are members of the CODEX sample with redshifts up to z~0…
A blind method to recover the mask of a deep galaxy survey
Pierluigi Monaco, Enea Di Dio, Emiliano Sefusatti
We present a blind method to determine the properties of a foreground contamination, given by a visibility mask, that affects a deep galaxy survey. Angular cross correlations of de…
Cluster Cosmology Constraints from the 2500 deg SPT-SZ Survey: Inclusion of Weak Gravitational Lensing Data from Magellan and the Hubble Space Telescope
S. Bocquet, J. P. Dietrich, T. Schrabback +77
We derive cosmological constraints using a galaxy cluster sample selected from the 2500~deg SPT-SZ survey. The sample spans the redshift range and contains 343 c…
Enrichment of the hot intracluster medium: numerical simulations
V. Biffi, F. Mernier, P. Medvedev
The distribution of chemical elements in the hot intracluster medium (ICM) retains valuable information about the enrichment and star formation histories of galaxy clusters, and on…
Dark Energy Survey Year 1 Results: Methods for Cluster Cosmology and Application to the SDSS
M. Costanzi, E. Rozo, M. Simet +83
We perform the first blind analysis of cluster abundance data. Specifically, we derive cosmological constraints from the abundance and weak-lensing signal of \redmapper\ clusters o…
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…
