Description

Photon-ALP oscillation results in the survival of gamma-rays from distant sources above TeV energies. Studies of CAST, Fermi-LAT, and IACT observed events that constrain the ALP parameters. We investigate the effect of photon-ALP oscillations on the gamma-ray spectra of the first extragalactic neutrino source, TXS 0506+056, for the observations of Fermi-LAT and MAGIC around the IC170922-A alert. Importantly, we studied the implications of photon-ALP oscillation on the counterpart γ-rays of the sub-PeV neutrinos observed from TXS 0506+056. We also show the diffuse γ-ray flux and their observability from the classes, FSRQs, HSP, and LISP, assuming similar gamma-ray emissions as TXS 0506+056.
