Probing photon-ALP oscillations from the flat spectrum radio quasar 4C+21.35
Flat spectrum radio quasar (FSRQ) is the most luminous blazar at the GeV energies. In this paper, we probe the photon-axion-like particle (ALP) oscillation effect on the latest very-high-energy (VHE) γ-ray observations of the FSRQ 4C+21.35 (PKS 1222+216). The γ-ray spectra are measured by the collab...
