Axion-like particles implications for high-energy astrophysics
G Galanti, M Roncadelli - Universe, 2022 - mdpi.com
We offer a pedagogical introduction to axion-like particles (ALPs) as far as their relevance
for high-energy astrophysics is concerned, from a few MeV to 1000 TeV. This review is self …
