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 characteristic optical variability time scale in jetted active galactic nuclei: a large gamma-ray emission sample
Dingrong Xiong, Mouyuan Sun, Jun-Xian Wang +14
The variability mechanisms from jetted AGNs are still under debate. Here the damped random walk (DRW) model, implemented through Gaussian Processe (GPs), is used to fit the l…
