X-ray observations of Clusters of Galaxies
M. Arnaud
X-ray observations of clusters provide key information on the dark matter, on the formation of structures in the Universe, and can be used to constrain the cosmological parameters.…
Structural and scaling properties of galaxy clusters: probing the physics of structure formation
M. Arnaud, G. W. Pratt, E. Pointecouteau
We present XMM-Newton studies of the total mass, gas density, temperature and entropy profiles in nearby hot and cool clusters, together with follow-up observations of distant clus…
XMM-Newton GT and AO-1 observations of SHARC galaxy clusters : RX J1120.1+4318 and RX J0256.5+0006
Sebastien Majerowicz, Monique Arnaud, David Lumb +1
We present the follow-up of two galaxy clusters from the Bright and Southern SHARC surveys observed with the XMM-Newton satellite. We studied the galaxy cluster RX J1120.1+4318 whi…
A multiscale regularized restoration algorithm for XMM-Newton data
H. Bourdin, E. Slezak, A. Bijaoui +1
We introduce a new multiscale restoration algorithm for images with few photons counts and its use for denoising XMM data. We use a thresholding of the wavelet space so as to remov…
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…
Abell 521: Dynamical analysis of a young cluster
S. Maurogordato, D. Proust, T. C. Beers +5
We present the results of a dynamical analysis of the rich X-Ray luminous galaxy cluster Abell 521, and discuss the nature of the arc-like structure first noted by Maurogordato et…
