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…
Gamma-ray Emission of 60Fe and 26Al Radioactivities in our Galaxy
W. Wang, T. Siegert, Z. G. Dai +7
The isotopes Fe and Al originate from massive stars and their supernovae, reflecting ongoing nucleosynthesis in the Galaxy. We studied the gamma-ray emission from the…
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…
Radioactive 26Al from the Scorpius-Centaurus Association
Roland Diehl, Michael G. Lang, Pierrick Martin +7
The Scorpius-Centaurus association is the most-nearby group of massive and young stars. As nuclear-fusion products are ejected by massive stars and supernovae into the surrounding…
INTEGRAL and Swift/XRT observations of the source PKS 0208-512
Shu Zhang, Werner Collmar, Diego F. Torres +3
The active galaxy PKS 0208-512, detected at lower energies by COMPTEL, has been claimed to be a MeV blazar from EGRET. We report on the most recent INTEGRAL observations of the bla…
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…
