Unveiling the multi-wavelength phenomenology of Anomalous X-ray Pulsars
GianLuca Israel, Luigi Stella, Stefano Covino +6
During 2002-2003 the number of IR-identified counterparts to the Anomalous X-ray Pulsars (AXPs) has grown to four (4U0142+614, 2E2259+584, 1E 1048-59 and 1RXS J170849-400910) out o…
Out of the Chorus Line : What Makes 1E1207.4-5209 a Unique Object?
A. De Luca, P. A. Caraveo, S. Mereghetti +3
The discovery of deep spectral features in the X-ray spectrum of 1E1207.4-5209 has pushed this Isolated Neutron Star (INS) out of the chorus line, since no other INS has shown sign…
The variable quiescence of Cen X-4
S. Campana, G. L. Israel, L. Stella +2
Cen X-4 is one of the best studied low-mass neutron star transients in quiescence. Thanks to XMM-Newton large throughput, Cen X-4 was observed at the highest signal to noise ever.…
The INTEGRAL Science Data Centre (ISDC)
T. J. -L. Courvoisier, R. Walter, V. Beckmann +17
The INTEGRAL Science Data Centre (ISDC) provides the INTEGRAL data and means to analyse them to the scientific community. The ISDC runs a gamma ray burst alert system that provides…
Unveiling the Nature of the 321 s Modulation in RX J0806.3+1527: Near-Simultaneous Chandra and VLT Observations
G. L. Israel, S. Covino, L. Stella +7
We report on the first near-simultaneous X-ray and optical observations of RX J0806.3+1527. The source is believed to be a 321s orbital period ultra-compact binary system hosting a…
GRB021125: the first GRB imaged by INTEGRAL
G. Malaguti, A. Bazzano, V. Beckmann +12
In the late afternoon of November 25, 2002 a gamma-ray burst (GRB) was detected in the partially coded field of view (about 7.3 deg from the centre) of the imager IBIS on board the…
