Scientific paper

We present a search for linear and circular polarization with the Very Large Array (VLA) at 8.4 GHz in 11 Low Luminosity AGNs (LLAGN). Due to the high phase stability of the VLA, and our careful data reduction, we can detect linear and circular polarization to 0.1 polarization in all but two of these sources, M81 and NGC 6500, with circular polarization only detected in M81. The detection of linear polarization supports the theory that LLAGN can be described by a disk/jet model. The detection of circular polarization and the non-detection of linear polarization show that M81 has very similar polarization properties to Sgr A* at this frequency. This work was supported by the NSF sponsored REU program. The National Radio Astronomy Observatory is facility of the National Science Foundation operated under a cooperative agreement by Associated Universities, Inc.
