WebThe observed dependence of AGN obscuration upon luminosity indicates a departure from the simplest unified model. The most-powerful AGNs may also be obscured by starbursts (e.g., Ballantyne 2008) or larger-scale gas clouds driven to the center of the galaxy by violent mergers or instabilities (e.g., Di Matteo et al. 2005; Hopkins et al. 2009). WebThe exact reason for the CL events is still unknown and subject to active research. The discovery of CLAGNs put serious challenges to the unified model of AGNs, which is a widely accepted model for AGN over the past 30 years. Our aim is to solve the mystery of the changing-look AGNs.
