SPI observations of positron annihilation radiation from the 4th galactic quadrant: Spectroscopy
V. Lonjou, G. Weidenspointner, J. Knodlseder +13
The status of the analysis of the electron/positron annihilation radiation performed by INTEGRAL/SPI in the 4th GALACTIC QUADRANT is reported. We use data from the first two Galact…
SPI observations of positron annihilation radiation from the 4th galactic quadrant: sky distribution
G. Weidenspointner, V. Lonjou, J. Knoedlseder +14
During its first year in orbit the INTEGRAL observatory performed deep exposures of the Galactic Center region and scanning observations of the Galactic plane. We report on the sta…
SPI/INTEGRAL observation of 1809 keV gamma-ray line emission from the Cygnus X region
J. Knödlseder, M. Valsesia, M. Allain +10
We present first results on the observation of 1809 keV gamma-ray line emission from the Cygnus X region with the SPI imaging spectrometer. Our analysis is based on data from the p…
