XMM-Newton Measurements of the Elemental Abundances in the Intracluster Medium
T. Tamura, J. S. Kaastra, J. A. M. Bleeker +1
Based on XMM-Newton observations of a sample of galaxy clusters, we have measured the elemental abundances (mainly O, Si, S, and Fe) and their spatial distributions in the intraclu…
Soft X-ray Spectra of Seyfert 2 Galaxies
Masao Sako, Ali Kinkhabwala, Steven M. Kahn +6
High resolution spectroscopic observations of Seyfert galaxies with Chandra and XMM-Newton allows us to study the detailed ionization and thermal structures of the X-ray absorbing/…
High resolution spectroscopy of nearby AGN
J. S. Kaastra
In this paper the potential of high resolution spectroscopy of nearby AGN with XEUS is discussed. The focus is upon the energy resolution that is needed in order to disentangle the…
X-ray powerful diagnostics for highly-ionized plasmas: He-like ions
D. Porquet, R. Mewe, J. S. Kaastra +2
The calculations of the ratios of the Helium-like ion X-ray lines from C V to Si XIII are revisited in order to apply the results to density, temperature and ionization process dia…
Soft X-ray Spectroscopy of NGC 1068 with XMM-Newton RGS and Chandra LETGS
A. Kinkhabwala, M. Sako, E. Behar +7
We present high-resolution soft-X-ray spectra of the prototypical Seyfert 2 galaxy, NGC 1068, taken with XMM-Newton RGS and Chandra LETGS. Its rich emission-line spectrum is domina…
A synoptic spectral study of Cassiopeia-A based on XMM-Newton and BeppoSax observations
Johan Bleeker, Jacco Vink, Kurt van der Heyden +3
In this paper we present recent image and spectral data of Cas-A obtained with XMM-Newton and BeppoSAX. Analysis of the hard X-ray continuum does not support an interpretation of t…
