Axion-like particles and the propagation of gamma rays over astronomical distances
S. V. Troitsky Institute for Nuclear Research, Russian Academy of Sciences, Moscow, Russia
Abstract:
In this brief review, possible manifestations of mixing between axion-like particles (ALPs) and energetic photons propagating over astronomical distances are considered. We discuss the evidence for the anomalous transparency of the Universe from observations of ensembles of distant gamma-ray sources, present the general formalism for the ALP-photon mixing and explain how this mechanism may remove the anomaly. We present relevant values of ALP parameters and discuss future ways to verify the scenario and to discover the particle in question.
