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…
Search for 1.809 MeV Emission of 26Al from nearby Supernova Remnants using COMPTEL
Juergen Knoedlseder, Uwe Oberlack, Roland Diehl +2
We report the negative results of our searches in COMPTEL data for 1.809 MeV gamma-ray line emission from four localized regions which contain nearby supernova remnants (SNRs). The…
1.8 MeV Emission from the Carina Region
J. Knoedlseder, K. Bennett, H. Bloemen +5
Significant 1.8 MeV emission from the Carina region has been detected by COMPTEL. The emission is concentrated within 6 degrees or less near the Carina nebula NGC 3372, one of the…
Modelling the 1.8 MeV Sky: Tests for Spiral Structure
J. Knoedlseder, N. Prantzos, K. Bennett +6
COMPTEL imaging analysis revealed a patchy, asymmetric distribution of diffuse 1.8 MeV emission along the Galactic plane, which is attributed to the decay of radioactive 26Al in th…
