Abstract
Recent studies have found that radio-AGN selected by radio-loudness show little difference in terms of their host galaxy properties when compared to non-AGN galaxies of similar stellar mass and redshift. Using new 1.4 GHz VLBI observations of the COSMOS field we find that approximately 49±8% of high-mass (M > 10¹⁰˙⁵ M⊙), high luminosity (L1.4 > 1024 W Hz−1) radio-AGN possess a VLBI detected counterpart. These objects show no discernible bias towards specific stellar masses, redshifts or host properties other than what is shown by the radio-AGN population in general. Radio-AGN that are detected in VLBI observations are not special, but form a representative sample of the radio-loud AGN population.
