Contrasting the UV and X-ray O VI Column Density Inferred for the Outflow in NGC 5548 (2003)
Arav, Nahum, Kaastra, Jelle, Steenbrugge, Katrien, Brinkman, Bert, Edelson, Rick, Korista, Kirk T., ...
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 robust lower limit on...
First XMM-Newton observations of an isolated neutron star: RXJ0720.4-3125 (2000)
Paerels, Frits, Motch, Christian, Haberl, Frank, Zavlin, Vyacheslav E., Zane, Silvia, Ramsay, Gavin, ...
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 band spectrum...
