Long-term Optical Spectroscopic Variability of BL Lacertae Object AO 0235+164

The changing-look (CL) phenomenon in active galactic nuclei (AGNs) poses a significant challenge to the unified model. As a special subclass of AGN, blazars provide valuable insights. The CL behavior in the blazars not only helps us probe the intrinsic physical properties of AGN structures but also...
