The first Suzaku observation of SGR 1806-20
P. Esposito, A. Tiengo, S. Zane +5
The soft gamma-ray repeater SGR 1806-20 has been attracting a lot of attention owing to the fact that in December 2004 it emitted the most powerful giant flare ever observed. Here…
Long term spectral variability in the soft gamma ray repeater SGR 1900+14
P. Esposito, S. Mereghetti, A. Tiengo +3
We present a systematic analysis of all the BeppoSAX data of SGR 1900+14. The observations spanning five years show that the source was brighter than usual on two occasions: ~20 da…
RX J1856.5-3754: Bare Quark Star or Naked Neutron Star ?
S. Zane, R. Turolla, J. J. Drake
Recent Chandra observations have shown that the soft X-ray spectrum from the isolated neutron star RX J1856.5-3754 is featureless and best fitted by a blackbody, in contrast with t…
Timing study of the isolated neutron star RX J0720.4-3125
Silvia Zane, Frank Haberl, Mark Cropper +4
We present a combined analysis of XMM-Newton, Chandra and Rosat observations of the isolated neutron star RX J0720.4-3125, spanning a total period of \sim 7 years. We develop a max…
X-ray line emission in Hercules X-1
M. A. Jimenez-Garate, C. J. Hailey, J. W. den Herder +2
We find line emission from the hydrogen- and/or helium-like ions of Ne, O, N and C in the low and short-on states of Her X-1, using the XMM-Newton Reflection Grating Spectrometer.…
XMM-Newton EPIC observations of Her X-1
G. Ramsay, S. Zane, M. A. Jimenez-Garate +2
We present spin-resolved X-ray data of the neutron star binary Her X-1. We find evidence that the Iron line at 6.4 keV originates from the same location as the blackbody X-ray comp…
