    Diffuse Galactic antimatter from faint thermonuclear supernovae in old stellar populations

    Our Galaxy hosts the annihilation of a few 1043 low-energy positrons every second. Radioactive isotopes capable of supplying such positrons are synthesized in stars, stellar remnants and supernovae. For decades, ...
