Stellar flares cannot explain the Galactic 511 keV emission
Saurabh Mittal, Thomas Siegert, Francesca Calore +12
The origin of the 511 keV line signal in the Milky Way remains unresolved despite decades of observations. The measured flux of $\sim 3 \times 10^{-3}\,\mathrm{ph\,cm^{-2}\,s^{-1}}…
Using Al to detect ongoing self-enrichment in young massive star clusters
Katarzyna Nowak, Martin G. H. Krause, Thomas Siegert +5
Self-enrichment is one of the leading explanations for chemical anomalies in globular clusters. In this scenario, various candidate polluter stars have been proposed to eject gas w…
Evolution of radioactive elements in the LMC: predictions for future gamma-ray surveys
Arianna Vasini, Francesca Matteucci, Emanuele Spitoni +1
Short-lived radionuclides, such as 26Al and 60Fe, are tracers of star formation. Therefore, their abundances can unravel the recent star formation history of the host galaxy. In vi…
Surround & Squash: The Interstellar Medium around Scorpius Centaurus OB2
Martin G. H. Krause, Andreas Burkert, Roland Diehl +7
We exploited observational constraints on stars, gas and nucleosynthesis ashes for the closest region of recent massive-star formation, Scorpius-Centaurus OB2, and combined them wi…
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…
