Monitoring AGNs with Hβ Asymmetry. V. Long-term Variation and Evolution of the Broad Hβ Emission-line Profiles

The physical origins of the diverse emission-line asymmetries observed in the spectra of active galactic nuclei (AGNs) are not completely understood. Monitoring the temporal variations of line profiles offers a promising approach to investigating the underlying physics. In this study, we present an...
