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 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…
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…
CMB Cosmological Parameter Estimation: Methods and Current Results
M. Douspis, J. G. Bartlett, A. Blanchard +1
The majority of present efforts to constrain cosmological parameters with cosmic microwave background (CMB) anisotropy data employ approximate likelihood functions, the time consum…
The ALADIN Interactive Sky Atlas
Francois Bonnarel, Pierre Fernique, Olivier Bienayme +6
The Aladin interactive sky atlas, developed at CDS, is a service providing simultaneous access to digitized images of the sky, astronomical catalogues, and databases. The driving m…
