Local Active Galactic Nuclei with Large Broad-Hα Variability Reside in Red Galaxies

Local Active Galactic Nuclei with Large Broad-Hα Variability Reside in Red Galaxies

Inspired by our serendipitous discovery of six active galactic nuclei (AGNs) with varying broad-H α fluxes over years from our search for intermediate-mass black holes (IMBHs), we conduct a systematic investigation of changing-look (CL) and large-variability AGNs. We collect all the CL AGNs at z
