Dual AGN candidates with double-peaked [O III] lines matching that of
  confirmed dual AGNs
  We have performed a spectral decomposition to search for dual active galactic
nuclei (DAGNs) in the Sloan Digital Sky Survey (SDSS) quasars with $z<0.25$.
Potential DAGN candidates are searched by referencing velocity offsets and
spectral shapes of double-peaked [O III] lines of known DAGNs. Out of 1271 SDSS
quasars, we have identified 77 DAGN candidates. Optical and mid-infrared
diagnostic diagrams are used to investigate the ionizing source in the DAGN
candidates. The optical diagnostic analysis suggests 93\% of them are powered
by AGNs, and mid-infrared diagnostic analysis suggests 97\% are powered by
AGNs. About 1/3 of the SDSS images of the DAGN candidates show signs of tidal
interaction, but we are unable to identify double nuclei in most of them due to
the low spatial resolution of the archival imaging data available for most of
the sample. The radio-loud fraction of the DAGN candidates ($\sim$10\%) is
similar to that of typical AGNs.
