New results on clusters of galaxies observed with XMM-Newton
D. M. Neumann, S. Majerowicz
Clusters of galaxies contain a hot gas, which emits in X-rays. X-ray telescopes such as XMM-Newton allow to study this plasma to obtain information on physical quantities of these…

J. G. Bartlett, N. Aghanim, M. Arnaud +16
The abundance of high-redshift galaxy clusters depends sensitively on the matter density $\OmM$ and, to a lesser extent, on the cosmological constant . Measurements of this abun…
