Abstract:Although the Fermi mission has increased our knowledge of {gamma}-ray AGN, many questions remain, such as the site of {gamma}-ray production, the emission mechanism, and the factors that govern the strength of the emission. Using data from a high radio band, 37GHz, uncontaminated by other radiation components besides the jet emission, we study these questions with averaged flux densities over the the first year of Fermi operations. We look for possible correlations between the 100MeV-100GeV band used by the Fermi satellite and 37GHz radio band observed at the Aalto University Metsahovi Radio Telescope, as well as for differences ...(more)
Abstract: (hide)
Our radio data include unpublished 37GHz flux density measurements from the Aalto University Metsahovi Radio Observatory. Metsahovi radio telescope is a radome-enclosed antenna with a diameter of 13.7m. It is situated in Kirkkonummi, Finland, at 60m above sea level.
