We have compared the optical emission line ratios of type 2 qu asars from Zakamska et al. with standard AGN photoionization model predictions, Seyf ert 2s, HII galaxies, and narrow line FRII radio galaxies. Moderate to high ionization narro w line radio galaxies and Seyfert 2s are indistinguishable from type 2 quasars based on their opt ical line ratios… CONTINUE READING
