Linear Polarization as a Probe of Gamma Ray Flaring Blazar Jets
arXiv:0912.3176
Abstract
We describe and present initial results from a Fermi cycle 2 program designed to monitor the behavior of the centimeter-band linear polarization and total flux density emitted by gamma-ray-bright blazars during flaring. The goal of the program is to identify changes in the magnetic field structure in the radio jet associated with gamma-ray flaring and ultimately to test whether gamma-ray flaring is associated with the onset of shocks in the radio jet. Light curves illustrating radio band variability patterns are shown for sample program sources.
