Is There a Dark Matter Signal in the Galactic Positron Annihilation Radiation?
R. E. Lingenfelter, J. C. Higdon, R. E. Rothschild
Assuming Galactic positrons do not go far before annhilating, a difference between the observed 511 keV annihilation flux distribution and that of positron production, expected fro…

The Galactic Positron Annihilation Radiation & The Propagation of Positrons in the Interstellar Medium
J. C. Higdon, R. E. Lingenfelter, R. E. Rothschild
We consider positron propagation in the interstellar medium and show that the positrons from the beta-plus decay chains of the radioactive nuclei Ni-56, Ti-44, and Al-26, produced…
