Lecture

Extreme Variability Quasars

Description

This lecture explores the extreme variability of quasars, focusing on the unified AGN model, SMBH with accretion disk & jet, emission line regions, and the role of the obscuring torus. It delves into the changing-look events attributed to accretion rate changes, sample statistics, emission line strength, Eddington ratio, and simple models for detection. The study also covers the correlation between g and i bands, redshift effects, and the implications of multi-messenger astronomy.
