Simulations of Sunyaev-Zel'dovich maps and their applications
J. Delabrouille, J. -B. Melin, J. G. Bartlett
We describe a fast method to simulate in a semi-analytical way consistent maps of the thermal, kinetic and polarised Sunyaev-Zel'dovich effect, featuring both cluster spatial corre…

The XMM-Newton Project
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…
