Variable AGN in the GALEX Time Domain Survey
  We searched the Northern Hemisphere Fields of the GALEX Time-Domain Survey
(TDS) for galaxies with UV variability indicative of active galactic nuclei
(AGNs). We identified 48 high-probability candidate AGNs from a parent sample
of 1819 galaxies in the NASA Sloan Atlas (NSA) catalog. We further
characterized these systems using optical spectroscopic diagnostics, WISE IR
color selection criteria, and spectral energy distribution (SED) modeling. Of
the 48 candidates, eight were identified as AGNs from optical emission lines,
two were identified by their IR colors, and 28 were identified through spectral
energy decomposition. Observational biases of each selection method are
discussed in connecting these AGNs subsamples to another. By selecting AGNs
based on UV variability, we also identified six low-mass AGNs candidates, all
of which would have been missed by spectroscopic selection.
