Abstract:We present a detailed statistical analysis of the correlation between radio and gamma-ray emission of the active galactic nuclei (AGNs) detected by Fermi during its first year of operation, with the largest data sets ever used for this purpose. We use both archival interferometric 8.4GHz data (from the Very Large Array and ATCA, for the full sample of 599 sources) and concurrent single-dish 15GHz measurements from the Owens Valley Radio Observatory (OVRO, for a sub sample of 199 objects). Our unprecedentedly large sample permits us to assess with high accuracy the statistical significance of the correlation, using a surrogate data method designed to simultaneously account for common-distance bias and the effect of a limited dynamical ...(more)

The gamma-ray sources in the present paper are a subset of those in the First Fermi-LAT catalog (1FGL; Abdo et al. 2010, Cat. J/ApJS/188/405). The 1FGL is a catalog of high-energy gamma-ray sources detected by the LAT during the first 11 months of the science phase of Fermi, i.e., between 2008 August 4 and 2009 July 4. In Table 1, we list the radio flux densities used for the present work, along with some basic information on the sources (position, optical and spectral type, redshift). In particular, we give the archival 8GHz interferometric flux density (with the corresponding reference) and the 15GHz single-dish flux density, when available.
