Using a Karl G. Jansky Very Large Array ( VLA ) L-band ( 1-2 GHz ) survey covering \sim 100 deg ^ { 2 } of the Stripe 82 field , we have obtained a catalogue of 2716 radio AGN .
For these AGN , we investigate the impact of galaxy density on 1.4 GHz radio luminosity ( L _ { 1.4 } ) .
We determine their close environment densities using the surface density parameter , \Sigma _ { N } , for N = 2 and N = 5 , which we bin by redshift to obtain a pseudo-3D galaxy density measure .
Matching the radio AGN to sources without radio detections in terms of redshift , K - band magnitude and ( g - K ) -colour index , we obtain samples of control galaxies and determine whether radio AGN environments differ from this general population .
Our results indicate that the environmental density of radio AGN and their radio luminosity are not correlated up to z \sim 0.8 , over the luminosity range 10 ^ { 23 } < ( L _ { 1.4 } / W Hz ^ { -1 } ) < 10 ^ { 26 } .
We also find that , when using a control sample matched in terms of redshift , K - band magnitude and colour , environments of radio AGN are similar to those of the control sample but with an excess of overdense regions in which radio AGN are more prevalent .
Our results suggest that the < 1 Mpc-scale galaxy environment plays some role in determining whether a galaxy produces a radio AGN .
The jet power , however , does not correlate with environment .
From this , we infer that secular processes e.g .
accretion flows of cold gas to the central black-hole are more critical in fuelling radio AGN activity than radio jet power .
