Evidence for Black Holes in Green Peas from WISE Colors and Variability

We explore the presence of active galactic nuclei (AGNs)/black holes in Green Pea galaxies (GPs), motivated by the presence of high-ionization emission lines such as He ii and [Ne iii ] in their optical spectra. In order to identify AGN candidates, we used mid-infrared (MIR) photometric observations...
