The XMM--NEWTON Omega Project: II.Cosmological implications from the high redshift L-T relation of X-ray clusters
S. C. Vauclair, A. Blanchard, R. Sadat +7
The evolution with redshift of the temperature-luminosity relation of X-ray galaxy clusters is a key ingredient to break degeneracies in the interpretation of X-ray clusters redshi…
The XMM--NEWTON Omega Project: I. The X-ray Luminosity - Temperature Relation at z>0.4
D. H. Lumb, J. G. Bartlett, A. K. Romer +9
(abridged) We describe XMM-Newton Guaranteed Time observations of a sample of eight high redshift (0.45<z<0.62) clusters. The goal of these observations was to measure the luminosi…
Approximating the Likelihood Function of CMB Experiments
J. G. Bartlett, A. Blanchard, M. Douspis +1
We discuss the problem of constraining cosmological parameters with cosmic microwave background band--power estimates. Because these latter are variances, they do not have gaussian…
New Territory: SZ Cluster Surveys
J. G. Bartlett, A. Blanchard, D. Barbosa
The potential of the Sunyaev-Zel'dovich (SZ) effect for cluster studies has long been appreciated, although not yet fully exploited. Recent technological advances and improvements…
