The unusually weak and exceptionally steep radio relic in Abell 2108
Gerrit Schellenberger, Simona Giacintucci, Lorenzo Lovisari +9
Mergers between galaxy clusters often drive shocks into the intra cluster medium (ICM), the effects of which are sometimes visible via temperature and density jumps in the X-ray, a…
Galaxy cluster number counts with individual lensing mass estimates: forecasts for Euclid
E. Artis, J-B Melin, J. G. Bartlett +1
Gradually, the CDM model starts to be challenged by observational data. Upcoming cosmological surveys will increase the number of detected galaxy clusters by several orders of m…
The X-CLASS survey: A catalogue of 1646 X-ray-selected galaxy clusters up to z1.5
E. Koulouridis, N. Clerc, T. Sadibekova +25
Cosmological probes based on galaxy clusters rely on cluster number counts and large-scale structure information. X-ray cluster surveys are well suited for this purpose, since they…
Chandra Observations of the Planck ESZ Sample: A Re-Examination of Masses and Mass Proxies
Felipe Andrade-Santos, Gabriel W. Pratt, Jean-Baptiste Melin +14
Using Chandra observations, we derive the proxy and associated total mass measurement, , for 147 clusters with from the Planck Early Su…
Impact of the calibration of the Halo Mass Function on galaxy cluster number count cosmology
Emmanuel Artis, Jean-Baptiste Melin, James G. Bartlett +1
The halo mass function (HMF) is a critical element in cosmological analyses of galaxy cluster catalogs. We quantify the impact of uncertainties in HMF parameters on cosmological co…
