The cosmological analysis of X-ray cluster surveys; III. 4D X-ray observable diagrams
M. Pierre, A. Valotti, L. Faccioli +4
Despite compelling theoretical arguments, the use of clusters as cosmological probes is, in practice, frequently questioned because of the many uncertainties impinging on cluster m…
SPIDERS: the spectroscopic follow-up of X-ray selected clusters of galaxies in SDSS-IV
Nicolas Clerc, Andrea Merloni, Yu-Ying Zhang +17
SPIDERS (The SPectroscopic IDentification of eROSITA Sources) is a program dedicated to the homogeneous and complete spectroscopic follow-up of X-ray AGN and galaxy clusters over a…
HIFLUGCS: X-ray luminosity -- dynamical mass relation and its implications for mass calibrations with the SPIDERS and 4MOST surveys
Yu-Ying Zhang, Thomas H. Reiprich, Peter Schneider +7
We present the X-ray luminosity (L) versus dynamical mass (M) relation for 63 nearby clusters in the HIFLUGCS. The luminosity measurements are obtained based on ~1.3 Ms of clean XM…
The XXL survey XV: Evidence for dry merger driven BCG growth in XXL-100-GC X-ray clusters
S. Lavoie, J. P. Willis, J. Democles +33
The growth of brightest cluster galaxies is closely related to the properties of their host cluster. We present evidence for dry mergers as the dominant source of BCG mass growth a…
