Classifying Intermediate-redshift Galaxies in SDSS: Alternative Diagnostic Diagrams

Classifying Intermediate-redshift Galaxies in SDSS: Alternative Diagnostic Diagrams

We select a sample of 1437 active galactic nuclei (AGN) from the catalog of the Sloan Digital Sky Survey galaxy properties from the Portsmouth group by detection of the high-ionization [Ne v ] 3426 Å emission line. We compare the fluxes of [Ne III ] 3869 Å, [O III ] 5007 Å, [O II ] 3726, 3728 Å, and...
