Monte Carlo modelling of the propagation and annihilation of nucleosynthesis positrons in the Galaxy
A. Alexis, P. Jean, P. Martin +1
We want to estimate whether the positrons produced by the beta plus decay of 26Al, 44Ti and 56Ni synthesised in massive stars and supernovae are sufficient to explain the 511 keV a…

Galactic annihilation emission from nucleosynthesis positrons
P. Martin, A. W. Strong, P. Jean +2
The Galaxy hosts a widespread population of low-energy positrons revealed by successive generations of gamma-ray telescopes through a bright annihilation emission from the bulge re…
