    • 26Al gamma rays from the Galaxy with INTEGRAL/SPI 

      Pleintinger, Moritz M. M.; Diehl, Roland; Siegert, Thomas; Greiner, Jochen; Krause, Martin G. H. (2023-03-30)
      Context. The presence of radioactive 26Al at 1.8 MeV reveals an ongoing process of nucleosynthesis in the Milky Way. Diffuse emission from its decay can be measured with gamma-ray telescopes in space. The intensity, line ...

    • Comparing simulated $^{26}$Al maps to gamma-ray measurements 

      Pleintinger, Moritz M. M.; Siegert, Thomas; Diehl, Roland; Fujimoto, Yusuke; Greiner, Jochen; Krause, Martin G. H.; Krumholz, Mark R. (2019-12-03)
      Context. The diffuse gamma-ray emission of $^{26}{\rm Al}$ at 1.8 MeV reflects ongoing nucleosynthesis in the Milky Way, and traces massive-star feedback in the interstellar medium due to its 1 Myr radioactive lifetime. ...

    • Constraints on positron annihilation kinematics in the inner Galaxy 

      Siegert, Thomas; Crocker, Roland M.; Diehl, Roland; Krause, Martin G. H.; Panther, Fiona H.; Pleintinger, Moritz M. M.; Weinberger, Christoph (2019-07-01)
      Context. The annihilation of cosmic positrons with electrons in the interstellar medium results in the strongest persistent γ-ray line signal in the sky. For the past 50 yr, this 511 keV emission - predominantly from the ...

    • Galactic Population Synthesis of Radioactive Nucleosynthesis Ejecta 

      Siegert, Thomas; Pleintinger, Moritz M. M.; Diehl, Roland; Krause, Martin G. H.; Greiner, Jochen; Weinberger, Christoph (2023-03-30)
      Diffuse gamma-ray line emission traces freshly produced radioisotopes in the interstellar gas, providing a unique perspective on the entire Galactic cycle of matter from nucleosynthesis in massive stars to their ejection ...

    • The Radioactive Nuclei 26Al and 60Fe in the Cosmos and in the Solar System 

      Diehl, Roland; Lugaro, Maria; Heger, Alexander; Sieverding, Andre; Tang, Xiaodong; Li, KuoAng; Li, Ertao; Doherty, Carolyn L.; Krause, Martin G. H.; Wallner, Anton; Prantzos, Nikos; Brinkman, Hannah E.; Hartogh, Jaqueline W. den; Wehmeyer, Benjamin; López, Andre Yagüe; Pleintinger, Moritz M. M.; Banerjee, Projival; Wang, Wei (2021-12-09)
      The cosmic evolution of the chemical elements from the Big Bang to the present time is driven by nuclear fusion reactions inside stars and stellar explosions. A cycle of matter recurrently re-processes metal-enriched stellar ...

    • Steady-state nucleosynthesis throughout the Galaxy 

      Diehl, Roland; Krause, Martin G. H.; Kretschmer, Karsten; Lang, Michael; Pleintinger, Moritz M. M.; Siegert, Thomas; Wang, Wei; Bouchet, Laurent; Martin, Pierrick (2021-06-01)
      The measurement and astrophysical interpretation of characteristic γ-ray lines from nucleosynthesis was one of the prominent science goals of the INTEGRAL mission and in particular its spectrometer SPI. Emission from 26Al ...
