Are Broad Mg II Galaxies Fading AGN?
We analyzed a sample of 494 galaxies from the Sloan Digital Sky Survey (SDSS) I-IV that have unusual properties. They display broadened Mg II $λ$2798 line emission, as would be expected of Type 1 active galactic nuclei (AGN). However, they have weak or absent broad Balmer lines though broadened Balm
