Nahum Arav, Jelle Kaastra, Katrien Steenbrugge +4
We compare X-ray and UV spectroscopic observations of NGC 5548. Both data sets show O VI absorption troughs associated with the AGN outflow from this galaxy. We find that the robus…

M. C. Weisskopf, B. Brinkman, C. Canizares +3
The Chandra X-Ray Observatory (CXO), the x-ray component of NASA's Great Observatories, was launched on 1999, July 23 by the Space Shuttle Columbia. After satellite systems activat…
First XMM-Newton observations of an isolated neutron star: RXJ0720.4-3125
Frits Paerels, Christian Motch, Frank Haberl +5
We present the high resolution spectrum of the isolated neutron star RXJ0720.4-3125, obtained with the Reflection Grating Spectrometer on XMM-Newton, complemented with the broad ba…
