dc.description.abstract | We investigate the stellar kinematics and stellar populations of 58 radio-loud galaxies of intermediate luminosities (L <SUB>3 GHz</SUB> > 10<SUP>23</SUP> W Hz<SUP>-1</SUP>) at 0.6 < z < 1. This sample is constructed by cross-matching galaxies from the deep VLT/VIMOS LEGA-C spectroscopic survey with the VLA 3 GHz data set. The LEGA-C continuum spectra reveal for the first time stellar velocity dispersions and age indicators of z ̃ 1 radio galaxies. We find that z ̃ 1 radio-loud active galactic nucleus (AGN) occur exclusively in predominantly old galaxies with high velocity dispersions: σ <SUB>*</SUB> > 175 km s<SUP>-1</SUP>, corresponding to black hole masses in excess of 10<SUP>8</SUP> M <SUB>☉</SUB>. Furthermore, we confirm that at a fixed stellar mass the fraction of radio-loud AGN at z ̃ 1 is five to 10 times higher than in the local universe, suggesting that quiescent, massive galaxies at z ̃ 1 switch on as radio AGN on average once every Gyr. Our results strengthen the existing evidence for a link between high black hole masses, radio loudness, and quiescence at z ̃ 1. | en_US |
