project: III. Gas mass fraction shape in high redshift clusters
Rachida Sadat, Alain Blanchard, Sebastien C. Vauclair +10
We study the gas mass fraction, behavior in project. The typical shape of high redshift galaxy clusters follows the global shape inf…
Cosmological Interpretation from High Redshift Clusters Observed Within the XMM-Newton -Project
Alain Blanchard
During the last ten years astrophysical cosmology has brought three remarkable results of deep impact for fundamental physics: the existence of non-baryonic dark matter, the (nearl…
The CLEF-SSH simulation project
A. C. da Silva, S. T. Kay, N. Aghanim +5
The CLEF-SSH simulation project is an international collaboration, involving the IAS, LATT and the University of Sussex, to produce large hydrodynamic simulations of large-scale st…
XMM-Omega project : cosmological implication from the high-z L-T relation of X-ray clusters
Sebastien C. Vauclair, Alain Blanchard, the XMM-Omega project collaboration
The evolution of the temperature distribution function (TDF) of X-ray clusters is kn own to be a powerful cosmological test of the density parameter of the Universe. Recent XMM obs…
Cosmological Parameter Estimation from CMB and X-ray clusters
M. Douspis, A. Blanchard, R. Sadat +1
We present the results of a combined analysis of cosmic microwave background (CMB) and X-ray galaxy clusters baryon fraction to deduce constraints over 6 in flationnary cosmologica…
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…
