Spectral and temporal variations of the isolated neutron star RX J0720.4-3125: new XMM-Newton observations
M. M. Hohle, F. Haberl, J. Vink +5
In the past, the isolated, radio-quiet neutron star RX J0720.4-3125 showed variations in the spectral parameters (apparent radius, temperature of the emitting area and equivalent w…
On the Putative Detection of z>0 X-ray Absorption Features in the Spectrum of Markarian 421
Andrew P. Rasmussen, Steven M. Kahn, Frits Paerels +3
In a series of papers, Nicastro et al. have reported the detection of z>0 OVII absorption features in the spectrum of Mrk421 obtained with the Chandra Low Energy Transmission Grati…
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…
The continued spectral evolution of the neutron star RX J0720.4-3125
Jacco Vink, Cor de Vries, Mariano Mendez +1
We observed the isolated neutron star RX J720.4-3125 with Chandra's Low Energy Transmission Grating Spectrometer, following the XMM-Newton discovery of long term spectral evolution…
XMM-NEWTON High Resolution Spectroscopy of NGC 5548
K. C. Steenbrugge, J. S. Kaastra, C. P. de Vries +1
We analyze a 137 ks exposure X-ray spectrum of the Seyfert 1 galaxy NGC 5548 obtained with the XMM-Newton Reflection Grating Spectrometer. Due to the long exposure time, the spectr…
XMM-Newton EPIC and RGS observations of LMC X-3
Kinwah Wu, Roberto Soria, Mathew Page +3
We report the results of preliminary analysis of the XMM_Newton EPIC and RGS observations of the candidate black-hole binary LMC X-3 between February and June 2000. The observation…
A High Resolution Spectroscopic Observation of CAL 83 with XMM-Newton/RGS
Frits Paerels, Andrew P. Rasmussen, H. W. Hartmann +4
We present the first high resolution photospheric X-ray spectrum of a Supersoft X-ray Source, the famous CAL~83 in the Large Magellanic Cloud. The spectrum was obtained with the Re…
First Light Measurements with the XMM-Newton Reflection Grating Spectrometers: Evidence for an Inverse First Ionisation Potential Effect and Anomalous Ne A bundance in the Coronae of HR 1099
A. C. Brinkman, E. Behar, M. Guedel +15
The RS CVn binary system HR 1099 was extensively observed by the XMM-Newton observatory in February 2000 as its first-light target. A total of 570 ks of exposure time was accumulat…
