Importance of axion-like particles for very-high-energy astrophysics
Marco Roncadelli, Alessandro De Angelis, Giorgio Galanti
Several extensions of the Standard Model predict the existence of Axion-Like Particles (ALPs), very light spin-zero bosons with a two-photon coupling. ALPs can give rise to observa…

Evidence for an axion-like particle from PKS 1222+216?
F. Tavecchio, M. Roncadelli, G. Galanti +1
The surprising discovery by MAGIC of an intense, rapidly varying emission in the energy range 70 - 400 GeV from the flat spectrum radio quasar PKS 1222+216 represents a challenge f…
