Simulations of galactic mergers predict that tidally-induced gas inflows can trigger synchronized accretion onto the supermassive black holes at the center of each galaxy. These should be observable as dual active galactic nuclei (dAGN) at kpc-scale separations. We test this prediction using a carefully selected sample of 35 radio galaxy pairs from the Stripe 82 field. Using optical spectroscopy from the Keck LRIS instrument, we confirm that 21 of these pairs have consistent redshifts, and thus are kinematic pairs in mergers; the remaining 14 are found to be isolated galaxies. We further classify the optical spectral signatures of the kinematic pairs via emission line ratios, equivalent widths, and excess of radio power above star-formation predicted outputs. We find 6 galaxies are classified as low ionization LINER- type AGN, and 7 are AGN/starburst composites. Most of the LINERs are found to be retired galaxies, while the composite types are more likely to have some AGN contribution to their ionizing spectra. All our kinematic pairs show evidence of radio power more than 1 dex above the level expected just from star-formation, suggestive of a radio AGN contribution. To rule out the possibility of radio emission from one galaxy overlapping with its companion, we analyze high resolution (0.3′′) imaging from the Very Large Array for 17 of the kinematic pairs. We find that 6 pairs host two separate radio cores thus confirming their status as dAGNs. The remaining 11 are single AGNs in each pair, with most exhibiting prominent jets/lobes overlapping their companion. Our final census will allow us to compute a corrected dAGN duty cycle, and test whether it is higher than predictions of stochastic fueling. While dAGNs are themselves rare, the merger process likely plays some part in their evolution.
