3 mm GMVA observations of total and polarized emission from blazar and radio galaxy core regions

3 mm GMVA observations of total and polarized emission from blazar and radio galaxy core regions Casadio, Carolina; Krichbaum, Thomas P.; Marscher, Alan P.; Jorstad, Svetlana G.; Gomez, Jose L.; Agudo, Ivan; Bach, Uwe; Kim, Jae-Young; Hodgson, Jeffrey A.; Zensus, Anton J. We present total and linearly polarized 3 mm Global mm-VLBI Array images of a sample of blazars and radio galaxies from the VLBA-BU-BLAZAR 7 mm monitoring program designed to probe the innermost regions of active galactic nuclei (AGN) jets and locate the sites of gamma-ray emission observed by the Fermi-LAT. The lower opacity at 3 mm and improved angular resolution, on the order of 50 microarcseconds, allow us to distinguish features in the jet not visible in the 7 mm VLBA data. We also compare two different methods used for the calibration of instrumental polarisation and we analyze the resulting images for some of the sources in the sample.
