Limits on axion-like particles from Mrk 421 with 4.5-year period observations by ARGO-YBJ and Fermi-LAT
Hai-Jun Li, Jun-Guang Guo, Xiao-Jun Bi +2
In this work, we investigate the axion-like particle (ALP)-photon oscillation effect in the spectra of the blazar Markarian 421 (Mrk 421) using 4.5 years of the Astrophysical Radia…

The implications of the axion like particle from the Fermi-LAT and H.E.S.S. observations of PG 1553+113 and PKS 2155-304
Junguang Guo, Hai-Jun Li, Xiao-Jun Bi +2
We investigate the axion like particle (ALP)-photon oscillation effect in the high energy -ray spectra of PG 1553+113 and PKS 2155-304 measured by Fermi-LAT and H.E.S.S.. The ch…
