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…
Line shape diagnostics of Galactic 26Al
K. Kretschmer, R. Diehl, D. H. Hartmann
The shape of the gamma-ray line from radioactive 26Al, at 1808.7 keV energy in the frame of the decaying isotope, is determined by its kinematics when it decays, typically 10^6 y a…
Disturbance Ecology from nearby Supernovae
D. H. Hartmann, K. Kretschmer, R. Diehl
Monte Carlo simulations of Galactic Supernovae are carried out to study the rate of nearby events, which may have a direct effect on Earth's ecology though ionizing radiation and c…
Diffuse gamma-ray line emission from multiple OB Associations in Cygnus
S. Plueschke, M. Cervino, R. Diehl +3
The COMPTEL observations of the diffuse galactic 1.809 MeV emission attributed to the radioactive decay of 26Al have confirmed the diffuse nature of this interstellar emission line…
