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…
MGGPOD: a Monte Carlo Suite for Gamma-Ray Astronomy
G. Weidenspointner, M. Harris, C. Ferguson +3
We have developed MGGPOD, a user-friendly suite of Monte Carlo codes built around the widely used GEANT (Version 3.21) package. The MGGPOD Monte Carlo suite and documentation are p…
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…
Al(26) Studies with INTEGRAL's Spectrometer SPI
R. Diehl, K. Kretschmer, G. Lichti +13
Al(26) radioactivity traces recent nucleosynthesis throughout the Galaxy, and is known to be produced in massive stars and novae. The map from its decay gamma-ray line suggests mas…
Search for gamma-ray line emission from the radioactive decay of 60Fe with SPI
J. Knodlseder, E. Cisana, R. Diehl +11
The search for gamma-ray line emission from the radioactive decay of 60Fe figures among the prime scientific objectives of the INTEGRAL mission. 60Fe is believed to be primarily pr…
