X-ray Evidence for Spectroscopic Diversity of Type Ia Supernovae: XMM observation of the elemental abundance pattern in M87
A. Finoguenov, K. Matsushita, H. Boehringer +2
We present the results of a detailed element abundance study of hot gas in M87, observed by XMM-Newton. We choose two radial bins, 1'-3' and 8'-16' (8'-14' for EMOS; hereafter the…
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…
XMM-Newton Observations of Galaxy Clusters: The Radial Temperature Profile of A2163
G. W. Pratt, M. Arnaud, N. Aghanim
XMM-Newton, with its high throughput and excellent spatial and spectral resolution, is an ideal instrument for spectro-imaging observation of clusters. Presented here is an XMM-New…
Impacts of a power-law non-thermal electron tail on the ionization and recombination rates
D. Porquet, M. Arnaud, A. Decourchelle
We have investigated the effects of a non-thermal electron population on the ionization and recombination rates. The considered electron distribution is defined as a Maxwellian fun…
