INTEGRAL, XMM-Newton and Rossi-XTE Observations of the State Transition of the X-ray Transient and Black Hole Candidate XTE J1720-318
Marion Cadolle Bel, Andrea Goldwurm, Jerome Rodriguez +14
We report the results of extensive high-energy observations of the X-ray transient and black hole candidate XTE J1720-318 performed with INTEGRAL, XMM-Newton and RXTE. The source,…
The INTEGRAL View of the Galactic Nucleus
A. Goldwurm, G. Belanger, P. Goldoni +15
We present the preliminary results of the observational campaign performed in 2003 to study the Galactic Nucleus with INTEGRAL. The mosaicked images obtained with the IBIS/ISGRI co…
Contribution of point sources to the soft gamma-ray Galactic emission
Regis Terrier, Francois Lebrun, Guillaume Belanger +6
The nature of the soft gamma-ray (20-200 keV) Galactic emission has been a matter of debate for a long time. Previous experiments have tried to separate the point source contributi…
The first broad-band persistent X-ray spectrum of the dipping low mass X-ray binary EXO 0748-676
L. Sidoli, A. N. Parmar, T. Oosterbroek
We report on the results of a BeppoSAX observation of the dipping LMXRB EXO 0748-676 performed in 2000 November. This is the first simultaneous observation of this source over the…
XMM-Newton sets the record straight: No X-ray emission detected from PSR J0631+1036
J. Kennea, F. Cordova, S. Chatterjee +5
The pulsar PSR J0631+1036 was discovered during a radio search of Einstein X-ray source error circles. A detection of a 288ms sinusoidal modulation in the ASCA lightcurve, the same…
Strongly absorbed quiescent X-ray emission from the X-ray transient XTE J0421+56
L. Boirin, A. N. Parmar, D. Lumb +2
We have observed the soft X-ray transient XTE J0421+56 in quiescence with XMM-Newton. The observed spectrum is highly unusual being dominated by a broad feature at 6.5 keV and can…
