On the polar caps of the 3 Musketeers
A. De Luca, P. A. Caraveo, S. Mereghetti +2
XMM-Newton observations of PSR B0656+14, PSR B1055-52 and Geminga have substantially increased the statistics available for these three isolated neutron stars, so apparently simila…
GRB 040403: a faint X-ray rich Gamma-ray Burst discovered by INTEGRAL
S. Mereghetti, D. Gotz, M. I. Andersen +13
GRB 040403 is one of the faintest gamma-ray bursts for which a rapid and accurate localization has been obtained. Here we report on the gamma-ray properties of this burst, based on…
The soft X-ray counterpart of the newly discovered INTEGRAL source IGRJ16195-4945
L. Sidoli, S. Vercellone, S. Mereghetti +1
The INTEGRAL satellite, during its regular scanning observations of the Galactic plane, has discovered several new X-ray sources emitting above 20 keV. The nature of the great majo…
INTEGRAL observations of the PSR B1259-63 / SS2883 system after the 2004 periastron passage
S. E. Shaw, M. Chernyakova, J. Rodriguez +3
The millisecond pulsar PSR B1259-63 and the Be star SS2883 are situated in a highly eccentric binary system, with orbital period ~3.4 years. We report on hard X-ray observations ob…
Phase-resolved spectroscopy of Geminga shows rotating hot spot(s)
P. A. Caraveo, A. De Luca, S. Mereghetti +2
Isolated neutron stars are seen in x-rays through their nonthermal and/or surface thermal emissions. XMM-Newton observations of the Geminga pulsar show a 43 electron volt spectrum…
A first XMM-Newton look at the relativistic double pulsar PSR J0737-3039
A. Pellizzoni, A. De Luca, S. Mereghetti +5
We present the results of a 50 ks long X-ray observation of the relativistic double pulsar system PSR J0737-3039 obtained with the XMM-Newton satellite in March 2004. The source ha…
