XMM-Newton high-resolution spectroscopy reveals the chemical evolution of M 87
N. Werner, H. Boehringer, J. S. Kaastra +3
We present here a study of chemical abundances in the giant elliptical galaxy M 87 using high-resolution spectra obtained with the Reflection Grating Spectrometers during two deep…
The O VII X-ray forest toward Markarian 421: Consistency between XMM-Newton and Chandra
J. S. Kaastra, N. Werner, J. W. A. den Herder +4
Recently the first detections of highly ionised gas associated with two Warm-Hot Intergalactic Medium (WHIM) filaments have been reported. The evidence is based on X-ray absorption…
Chemical evolution in Sersic 159-03 observed with XMM-Newton
J. de Plaa, N. Werner, A. M. Bykov +6
Using a new long X-ray observation of the cluster of galaxies Sersic 159-03 with XMM-Newton, we derive radial temperature and abundance profiles using single- and multi-temperature…
