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…

A Minimal Stochastic Variability Model of Blazars in Turbulent Cascade
Nan Ding, Yunyong Tang, Qiusheng Gu +2
In this paper, we propose a novel minimal physical model to elucidate the long-term stochastic variability of blazars. The model is built on the realistic background of magnetized…
