I will present total and polarized intensity images at ultra-high resolution (0.1 milliarcseconds) of a sample of 33 gamma-ray blazars obtained monthly with the Very Long Baseline Array (VLBA) at 43 GHz, starting in Summer 2008 when the Fermi Gamma-Ray Space Telescope began to operate. The VLBA observations determine the flux and polarization of the millimeter-wave core and other features of the jet, as well as the motions of bright superluminal knots. Comparison of the variability in gamma-rays and in the mm-wave core indicates a similarity as measured by a variability index defined by Aller et al. (2003). Analysis of the variability along with the jet kinematics suggests that in blazars with high variability indices (e.g. AO 0235+164, 3C 279, and PKS 1510-089), strong gamma-ray activity, lasting more than a month, occurs as a new superluminal knot propagates down the inner jet and passes through the core.
This research is funded in part by NASA through Fermi Guest Investigator grants NNX08AV65G and NNX08AV61G, and by the National Science Foundation through grant AST-0907893.
