Steady-state nucleosynthesis throughout the Galaxy
Roland Diehl, Martin G. H. Krause, Karsten Kretschmer +6
Measurement and astrophysical interpretation of characteristic gamma-ray lines from nucleosynthesis was one of the prominent science goals of the INTEGRAL mission and in particular…
INTEGRAL/SPI -ray line spectroscopy
Roland Diehl, Thomas Siegert, Jochen Greiner +7
INTEGRAL/SPI is a space-based coded mask telescope featuring a 19-element Germanium detector array for high-resolution gamma-ray spectroscopy, encapsulated in a scintillation detec…
26Al kinematics: superbubbles following the spiral arms? Constraints from the statistics of star clusters and HI supershells
Martin G. H. Krause, Roland Diehl, Yiannis Bagetakos +6
High energy resolution spectroscopy of the 1.8 MeV radioactive decay line of 26Al with the SPI instrument on board the INTEGRAL satellite has recently revealed that diffuse 26Al ha…
Kinematics of massive star ejecta in the Milky Way as traced by 26Al
Karsten Kretschmer, Roland Diehl, Martin Krause +5
Massive stars form in groups and their winds and supernova explosions create superbubbles up to kpc in size. Their ejecta are important for the dynamics of the interstellar medium…
SPI Measurements of Nucleosynthesis Gamma-Rays
Roland Diehl, Frauke Alexander, Martin Krause +4
Studies based on the gamma-ray lines from radioactive decay of unstable isotopes produced in massive-star and supernova nucleosynthesis have been among INTEGRAL's prominent science…
Spectral and intensity variations of Galactic 26^Al emission
W. Wang, M. G. Lang, R. Diehl +9
Gamma-ray line emission from the radioactive decay of 26Al reflects nucleosynthesis in massive stars and supernovae. We use INTEGRAL 26Al measurements to characterize the distribut…
