摘要

正电子湮灭辐射的观测解决了银河天体物理学中的一些基本问题,包括核合成、超新星、黑洞和星际介质。由正电子湮灭产生的0.511 MeV线叠加在一个连续体上,这在很大程度上可能是宇宙射线电子的轫致辐射。这些电子沉积的能量可能对星际介质有重要的意义。

Diffuse <1 MEV Galactic gamma rays
Observations of positron electron annihilation radiation address some fundamental problems in Galactic astrophysics, including nucleosynthesis, supernovae, black holes, and the interstellar medium. The 0.511 MeV line resulting from positron annihilation is superposed on a continuum which probably is, in large part, bremsstrahlung of cosmic ray electrons. The power deposited by these electrons could have important implications for the interstellar medium.
