Searching for changing-state agns in massive data sets. i. applying deep learning and anomaly-detection techniques to find agns with anomalous variability behaviors
The classic classification scheme for active galactic nuclei (AGNs) was recently challenged
by the discovery of the so-called changing-state (changing-look) AGNs. The physical …
