Positron Annihilation in the Galaxy
Carolyn A. Kierans, John F. Beacom, Steve Boggs +27
The 511 keV line from positron annihilation in the Galaxy was the first -ray line detected to originate from outside our solar system. Going into the fifth decade since the disc…
Science with e-ASTROGAM (A space mission for MeV-GeV gamma-ray astrophysics)
A. De Angelis, V. Tatischeff, I. A. Grenier +248
e-ASTROGAM (enhanced ASTROGAM) is a breakthrough Observatory space mission, with a detector composed by a Silicon tracker, a calorimeter, and an anticoincidence system, dedicated t…
On the origin and composition of Galactic cosmic rays
N. Prantzos
The composition of Galactic Cosmic Rays (GCR) presents strong similarities to the standard (cosmic) composition, but also noticeable differences, the most important being the high…
Nucleosynthesis and gamma-ray lines
Nikos Prantzos
Astrophysical gamma-ray spectroscopy is an invaluable tool for studying nuclear astrophysics, supernova structure, recent star formation in the Milky Way and mixing of nucleosynthe…
The 511 keV emission from positron annihilation in the Galaxy
N. Prantzos, C. Boehm, A. M. Bykov +9
The first gamma-ray line originating from outside the solar system that was ever detected is the 511 keV emission from positron annihilation in the Galaxy. Despite 30 years of inte…
Relative frequencies of supernovae types: dependence on host galaxy magnitude, galactocentric radius and local metallicity
S. Boissier, N. Prantzos
Context: Stellar evolution theory suggests that the relationship between number ratios of supernova (SN) types and metallicity holds important clues as to the nature of the progeni…
