Detection of hard X-ray emission from the Galactic nuclear region with INTEGRAL
G. Belanger, A. Goldwurm, P. Goldoni +13
This letter presents the first results of an observational campaign to study the Galactic Centre with INTEGRAL. The mosaicked images obtained with the IBIS/ISGRI coded aperture ins…
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…
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…
Early SPI/INTEGRAL contraints on the morphology of the 511 keV line emission in the 4th galactic quadrant
J. Knodlseder, V. Lonjou, P. Jean +11
We provide first constraints on the morphology of the 511 keV line emission from the galactic centre region on basis of data taken with the spectrometer SPI on the INTEGRAL gamma-r…
INTEGRAL/SPI ground calibration
D. Attié, B. Cordier, M. Gros +30
Three calibration campaigns of the spectrometer SPI have been performed before launch in order to determine the instrument characteristics, such as the effective detection area, th…
