Axion effects on gamma-ray spectral irregularities with AGN redshift uncertainty
Hai-Jun Li, Wei Chao
We investigate the photon-axionlike particle (ALP) oscillation effects on TeV gamma-ray spectral irregularities from the uncertain redshift active galactic nuclei (AGN) VER J0521+2…
Axion-like Dark Matter from the Type-II Seesaw Mechanism
Wei Chao, Mingjie Jin, Hai-Jun Li +1
Although axion-like particles (ALPs) are popular dark matter candidates, their mass generation mechanisms as well as cosmic thermal evolutions are still unclear. In this letter, we…
Primordial black holes induced stochastic axion-photon oscillations in primordial magnetic field
Hai-Jun Li
Primordial black holes (PBHs) can be produced in the very early Universe due to the large density fluctuations. The cosmic background of axion-like particles (ALPs) could be non-th…
Probing photon-ALP oscillations from the flat spectrum radio quasar 4C+21.35
Hai-Jun Li
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 ver…
