Polarimetry of optically selected BL Lacertae candidates from the SDSS
Polarimetry of optically selected BL Lacertae candidates from the SDSS
We present and discuss polarimetric observations of 182 targets drawn from an optically selected sample of 240 probable BL Lac candidates out of the SDSS compiled by Collinge et al. (2005, AJ, 129, 2542). In contrast to most other BL Lac candidate samples extracted from the SDSS, its radio- and/or …
