Light Elements and Cosmic Rays in the Early Galaxy
R. Ramaty, B. Kozlovsky, R. E. Lingenfelter
We derive constraints on the cosmic rays responsible for the Be and part of the B observed in stars formed in the early Galaxy: the cosmic rays cannot be accelerated from the ISM;…
Interstellar Gamma Ray Lines from Low Energy Cosmic Ray Interactions
Reuven Ramaty
Evidence for the existence of low energy cosmic rays in the Galaxy comes from the COMPTEL observations of gamma ray line emission from Orion, and also from light element abundance…
TGRS Observation of the Galactic Center Annihilation Line
B. J. Teegarden, T. L. Cline, N. Gehrels +8
The TGRS (Transient Gamma-Ray Spectrometer) experiment is a high-resolution germanium detector launched on the WIND satellite on Nov. 1, 1994. Although primarily intended to study…
Low Energy Cosmic Ray Interactions in Astrophysics
Reuven Ramaty
Solar flare observations are used to demonstrate the new technique of abundance determination based on gamma ray line emission produced by accelerated particle bombardment. Some of…
