Frequency and Abundance of Binary Supermassive Black Holes from Optical Variability Surveys (Fabulovs): Hubble Space Telescope Imaging of Radial-velocity-selected Binary Candidates

Subparsec binary supermassive black holes (BSBHs) should be common from galaxy mergers, yet direct evidence has been elusive. We present Hubble Space Telescope (HST)/WFC3IR F160W imaging for a sample of eight candidate subparsec BSBHs at redshifts z  ∼ 0.1–0.5, as well as cross-comparison with a sam...
