Cosmic Colliders in Binary Blazars Probing Ultra-High-Energy Particle Physics
Giorgio Galanti
While terrestrial colliders and fixed-target cosmic-ray interactions are bounded at center-of-mass (CM) energies , we demonstrate t…
Axion-like Particle Effects on Photon Polarization in High-Energy Astrophysics
Giorgio Galanti
In this review, we present a self-contained introduction to axion-like particles (ALPs) with a particular focus on their effects on photon polarization: both theoretical and phenom…
Dark Matter Line Searches with the Cherenkov Telescope Array
S. Abe, J. Abhir, A. Abhishek +562
Monochromatic gamma-ray signals constitute a potential smoking gun signature for annihilating or decaying dark matter particles that could relatively easily be distinguished from a…
Axion-like Particles Implications for High-Energy Astrophysics
Giorgio Galanti, Marco Roncadelli
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 s…
Photon-ALP interaction as a measure of initial photon polarization
Giorgio Galanti
Axion-like particles (ALPs) are very light, neutral, spin zero bosons predicted by superstring theory. ALPs interact primarily with two photons and in the presence of an external m…
Physics potential of the International Axion Observatory (IAXO)
E. Armengaud, D. Attie, S. Basso +88
We review the physics potential of a next generation search for solar axions: the International Axion Observatory (IAXO). Endowed with a sensitivity to discover axion-like particle…
