XMM-Newton and VLT observations of the isolated neutron star 1E 1207.4-5209
A. De Luca, S. Mereghetti, P. A. Caraveo +3
In August 2002, XMM-Newton devoted two full orbits to the observation of 1E 1207.4-5209, making this isolated neutron star the most deeply scrutinized galactic target of the missio…
HST and VLT observations of Pulsars and their Environments
Roberto P. Mignani, Andrea De Luca, Patrizia A. Caraveo
The state of the art of optical studies of Isolated Neutron Stars (INSs) and their Pulsar Wind Nebulae (PWNe) is reviewed. In addition, results obtained from recent HST and VLT obs…
SPI/INTEGRAL in-flight performance
J. -P. Roques, S. Schanne, A. von Kienlin +23
The SPI instrument has been launched on-board the INTEGRAL observatory on October 17, 2002. SPI is a spectrometer devoted to the sky observation in the 20 keV-8 MeV energy range us…
SPI/INTEGRAL observation of the Cygnus region
L. Bouchet, E. Jourdain, J. -P. Roques +22
We present the analysis of the first observations of the Cygnus region by the SPI spectrometer onboard the Integral Gamma Ray Observatory, encompassing 600 ks of data. Thr…
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…
Early SPI/INTEGRAL measurements of galactic 511 keV line emission from positron annihilation
P. Jean, J. Knoedlseder, V. Lonjou +18
We report the first measurements of the 511 keV line emission from the Galactic Centre (GC) region performed with the spectrometer SPI on the space observatory INTEGRAL (Internatio…
