Influence of a carbon over-coat on the X-ray reflectance of XEUS mirrors
D. H. Lumb, F. E. Christensen, C. P. Jensen +1
We describe measurements of the X-ray reflectance in the range 2 to 10 keV of samples representative of coated silicon wafers that are proposed for the fabrication of the XEUS (X-r…
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…
XMM-Newton observations of the relaxed, high-redshift galaxy cluster ClJ0046.3+8530 at z=0.62
B. J. Maughan, L. R. Jones, D. Lumb +2
A detailed analysis of XMM observations of ClJ0046.3+8530 (z=0.624) is presented. The cluster has a moderate temperature (kT=4.1+/-0.3keV) and appears to be relaxed. Emission is de…
In-orbit Vignetting Calibrations of XMM-Newton Telescopes
D. H. Lumb, A Finoguenov, R Saxton +4
We describe measurements of the mirror vignetting in the XMM-Newton Observatory made in-orbit, using observations of SNR G21.5-09 and SNR 3C58 with the EPIC imaging cameras. The in…
Timing Analysis of the Isolated Neutron Star RX J0720.4-3125 Revisited
Mark Cropper, Frank Haberl, Silvia Zane +1
We present a reanalysis of the X-ray data for RX J0720.4-3125 presented in Zane et al. (2002), using more data recently available from XMM-Newton and Chandra. This analysis also co…
An XMM and Chandra view of massive clusters of galaxies to z=1
L. R. Jones, B. J. Maughan, H. Ebeling +7
The X-ray properties of a sample of high redshift (z>0.6), massive clusters observed with XMM-Newton and Chandra are described, including two exceptional systems. One, at z=0.89, h…
