ADC_Keywords: Active gal. nuclei ; Radio continuum ; Surveys Keywords: galaxies: active - radio continuum: galaxies - surveys - techniques: interferometric Abstract: The VLBI Space Observatory Programme (VSOP) mission is a Japanese-led project to study radio sources with submilliarcsecond angular resolution, using an orbiting 8m telescope on board the satellite HALCA with a global Earth-based array of telescopes. A major program is the 5GHz VSOP Survey Program, which we supplement here with Very Long Baseline Array observations to produce a complete and flux density-limited sample. Using statistical methods of analysis of the observed visibility amplitude versus projected (u, v) spacing, we have determined the angular size and brightness temperature distribution of bright radio emission from active galactic nuclei.

Note (1): Redshift and identification for J1501-3918 and J1658-0739 from I.A.G. Snellin & P.G. Edwards (2004, private communication); redshift for J1522-2730 from Heidt et al. (2004A&A...418..813H). Note (2): Optical identification, defined as follows: q = quasar; e = elliptical galaxy; g = faint galaxy (>24mag); b = BL Lac object; e = empty field. Note (3): Status of the survey observation, defined as follows: A = AGN sample and observed with VSOP; B = AGN sample, but not yet observed with VSOP or reduced; C = AGN sample, but too faint to be observed with VSOP; D = Removed from AGN sample.
