WebThe rare case of changing-look (CL) active galactic nuclei (AGNs), with the appearance or disappearance of broad Balmer emission lines within a few years, challenges our understanding of the AGN unified model. We present a sample of 21 new CL AGNs at 0.08< z< 0.58, which doubles the number of such objects known to date. 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).
