The mass-concentration relation in massive galaxy clusters at redshift ∼ 1.

SERENO M. and COVONE G.

Abstract (from CDS):

Mass and concentration of clusters of galaxies are related and evolving with redshift. We study the properties of a sample of 31 massive galaxy clusters at high redshift, 0.8 ≲ z ≲ 1.5, using weak and strong lensing observations. Concentration is a steep function of mass, c200 ∝ M200-0.83±0.39, with higher redshift clusters being less concentrated. Mass and concentration from the stacked analysis, M200 = (4.1±0.4) x 1014M☉h-1 and c200 = 2.3±0.2, are in line with theoretical results extrapolated from the local Universe. Clusters with signs of dynamical activity preferentially feature high concentrations. We discuss the possibility that the whole sample is a mix of two different kinds of haloes. Overconcentrated clusters might be accreting haloes out of equilibrium in a transient phase of compression, whereas less concentrated ones might be more relaxed.
