Spatially resolved spectroscopy to confirm or disprove dual active galactic nuclei

McGurk, R.C.; Max, Claire; Medling, Anne; Shields, G.A.

Description

When galaxies merge, gas accretes onto both central supermassive black holes. Thus, one expects to see dual active galactic nuclei (AGNs) in a fraction of galaxy mergers. Candidates for galaxies containing dual AGNs have been identified by the presence of double-peaked narrow [O III] emission lines and by high spatial resolution images of close galaxy pairs. 30% of double-peaked narrow [OIII] emission line SDSS AGNs have two spatial components within a 3 radius. However, spatially resolved...[Show more]
