Polarimetry on RGB BL lacs

PDF Version Also Available for Download.

Description

We present results on polarimetry on RGB BL Lacs. This sample has its roots in ROSAT and Green Bank catalogues. The broad band spectral energy distribution of RGB BL Lacs differs from the ''traditional'' BL Lacs, filling the gap between two extremes, HBLs and LBLs. We found that the polarization properties of the sample are also intermediate to HBLs and LBLs. The highest measured polarization was {minus}19% and {minus}60% of the objects had high polarization. Our results suggests that there is a connection between HBLs and LBLs and between the synchrotron peak frequency and the degree of polarization.
