[27.12] VLBA Circular Polarization Observations of 133 AGN

D. Homan (Denison University), MOJAVE Collaboration

We present circular polarization results from the MOJAVE program to monitor a complete sample of extra-galactic radio jets at parsec-scale resolution using the Very Long Baseline Array (VLBA) at 15 GHz. The MOJAVE sample is flux limited on the basis of VLBA scale emission and includes 133 sources. We present first epoch circular polarization results from the monitoring campaign. We find that circular polarization is predominantly associated with the unresolved jet cores, and while linear polarization in jet cores is almost always stronger than circular polarization, we find no clear relationship between them. Observations of a few nearby sources in our sample suggest that, due to depolarization effects, the circular and linear polarization we observe may be produced in different parts of the unresolved jet cores, with the circular polarization coming from smaller jet radii.
