Relevance of VHE Blazar Spectra Models with Axion-Like Particles

Hai-Jun Li

The oscillation of photons and axion-like particles (ALPs) in the astrophysical magnetic fields could modify the measured very high energy (VHE; $E ≳ 100 GeV$ )…

Searching for Axion-Like Particles with the Blazar Observations of MAGIC and Fermi-LAT

Hai-Jun Li, Xiao-Jun Bi, Peng-Fei Yin

We explore the axion-like particle (ALP)-photon oscillation effect in the $γ$ -ray spectra of the blazars Markarian 421 (Mrk 421) and PG 1553+113, which are measured by the Major At…
