A Single Radio Source in the High-redshift Dual AGN LBQS 0302-0019

Abstract

By discovering a narrow-line emitter embedded in an extended Ly-alpha nebula, Husemann et al. (2018) found that the luminous radio-quiet quasar LBQS 0302-0019 is a dual active galactic nucleus (AGN) system. By combining available archival radio interferometric data taken at 8.4 GHz with the Very Large Array (VLA), we found that the weak 0.4-mJy radio source in this system positionally coincides with the unobscured optical quasar while its newly discovered obscured companion has no detectable radio emission (<0.045 mJy/beam, 3-sigma image noise level). However, the non-detection of this object with the VLA does not rule out the presence of a radio-quiet AGN there.
