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…

Possible evidence for the 478 keV emission line from Be decay during the outburst phases of V1369 Cen
L. Izzo, T. Siegert, P. Jean +4
After decades of uncertainty about the origin of lithium, recent evidence suggests Galactic novae as its main astrophysical source. In this work, we present possible evidence for t…

Diffuse Galactic emission spectrum between 0.5 and 8.0 MeV
Thomas Siegert, Joanna Berteaud, Francesca Calore +2
The last measurement of the diffuse emission spectrum of the Milky Way in the megaelectronvolt (MeV) photon energy range was performed by CGRO/COMPTEL more than 20 years ago. We re…
