Sleeping Giants Arise: Monitoring the Return of Three Changing-look Quasars to Their High States
Changing-look quasars (CLQs) challenge many models of the quasar central engine. Their extreme variability in both the continuum and broad emission-line fluxes on timescales on the order of years is difficult to explain. To investigate the cause of the observed transitions, we present new contempora...
