The Variable Optical Polarization of J0948+0022

The results of monitoring the optical polarization and the gamma-ray flux for the radio-loud narrow-line Seyfert 1 galaxy is reported. We have detected a weak correlation between the gamma-ray variability and the optical variability. However, these observations do not provide conclusive evidence that the emissions are due to a relativistic jet oriented close to the line-of-sight to the observer.

3C 279 in an Optical Faint State

AGN, such as blazars, are most often observed during flare states, primarily due to ease of detection. We report microvariability observations of one blazar, however, while in a historically low state. Comparisons of the amplitude of the variability between high and low states are made. These observations strongly suggest that the relativistic jet associated with the central source of this object is responsible for the observed microvariability (as opposed to a source within the accretion disk).
