Polarization and beaming effect for BL Lacertae objects.

FAN J.H., CHENG K.S., ZHANG L. and LIU C.H.

Abstract (from CDS):

We derive a relation between the observed polarization and beaming factor (Doppler factor) and compare this relation with the observed data for BL Lac objects. Our results indicate that the high optical polarization is correlated to the beaming effect and the difference in polarizations between X-ray selected (XBLs) and radio selected (RBLs) BL Lac objects is due to the difference in their beaming effects.
