Research Advances in Optical Polarization of Blazar
摘要
Abstract
Blazars are a subclass of active galactic nucleus (AGNs) which have the jet al-most aligned with the line of sight. High polarization is a typical feature of blazars which distinguishes them from other AGNs. The polarization of blazars is generally thought to be from the synchrotron radiation of the relativistic electrons in the jet. Optical polarization observations can constrain the jet properties and provide supplement information on the light curve properties in other wavelengths. The paper focuses on the study of the optical po-larization of blazars. Firstly, the general background of blazars and their polarization are introduced. Then, the mechanism of the blazar polarization, the depolarization effect, the study of the frequency dependence polarization(FDP)behavior,the correlation between the high-energy flare and the optical polarization are presented. Finally, the prospects of the optical polarization study on blazars are outlined.关键词
