The X-ray surface brightness profiles of hot galaxy clusters up to z~0.8: evidence for self-similarity and constraints on Omega_0
M. Arnaud, N. Aghanim, D. M. Neumann
We study the ROSAT surface brightness profiles of a sample of 25 distant (0.3<z<0.83) hot (kT>3.5keV) clusters. For both open and flat cosmological models, the derived emission mea…

Self-similarity of clusters of galaxies and the L_X-T relation
D. M. Neumann, M. Arnaud
In this paper based on ROSAT/PSPC data we investigate the emission measure profiles of a sample of hot clusters of galaxies (kT>3.5keV) in order to explain the differences between…
