MeV dark matter decay forecasts for the COSI mission
Robin Anthony-Petersen, Orion Ning, Yu Watanabe +21
The decay of dark matter (DM) is a generic prediction of many particle physics models, producing distinctive monochromatic signatures in environments such as the Galactic halo. Sea…
Cosmological - Pair-Production Background
Mika A. Gelowicz, Thomas Siegert, Saurabh Mittal +10
The origin of positrons is one of the unsolved puzzles in astrophysics as the majority of sources are still unidentified. The Cosmic Photon Background (CPB) is the isotropic radiat…
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}}…
On the Possibility of an Extragalactic Positron Annihilation Signal
Thomas Siegert, Hiroki Yoneda
With 20 years of INTEGRAL/SPI observations, Yoneda et al. (2025) created the most detailed map of the positron annihilation line at 511keV. While central bulge and extended disk ar…
