The radiation from accreting X-ray pulsars was expected to be highly polarized, with some estimates for the polarization degree of up to 80%. However, phase-resolved and energy-resolved polarimetry of X-ray pulsars is required in order to test differ

During the past decade, the field of astrophysics has progressed at an impressive rate. This was reflected by the topics discussed at the workshop from which this book eminated. These topics include the inflationary universe; the large-scale structur

XMM-Newtondiscovery of a sharp spectral feature at ∼ 7 keV in the narrow-line Seyfert 1 galaxy 1H 0707−495

We report the first detection of a sharp spectral feature in a Narrow-Line Seyfert 1 galaxy. Using XMM-Newton we have observed 1H0707-495 and find a drop in flux by a factor of more than 2 at a rest-frame energy of ~7 keV without any detectable narro
