Circular polarization effects induced by photon-axion mixing in astrophysical environments
Meng Wang, Nan Ding, Qiusheng Gu +2
Axions and axion-like particles (ALPs) are compelling candidates for dark matter and new physics beyond the Standard Model. Photon-axion mixing in external magnetic fields modifies…

Systematic Search and Study of Short-Timescale Flare Structures in BL Lac object Gamma-ray Emission
Jinjie Yu, Nan Ding, Junhui Fan +2
We present here the first systematic search of short timescale -ray flares from 29 high Galactic latitude BL Lac objects over 14 years of Fermi Large Area Telescope data. Using…

Transient quasi-periodic oscillations in the gamma-ray light curves of bright blazars
Junping Chen, Jinjie Yu, Weitian Huang +1
Transient quasi-periodic oscillations (QPOs) are extremely interesting observational phenomena. However, the precise physical mechanisms leading to their generation are still hotly…
