耀变体的偏振与核主导系数
Polarization and Core-Dominance Parameter for Blazars
摘要
Abstract
Radio and optical polarizations are collected for a blazar sample.The relationships between polarization and jet parameters are investigated.The analysis results indicate that (1) polarization in BL Lac is higher than in FSRQs,and the core dominance parameter R and the ratio f are both positively correlated with intrinsic radio and optical polarizations;(2) the jet type is spherical;(3) BL Lacs and FSRQs have a similar correlation between the intrinsic polarization and jet parameters (log R and f).关键词
