Classical quasar winds, which are gas outflows from the accretion disks surrounding supermassive black holes, play a crucial role in regulating the coevolution between the black hole and its host galaxy (Kormendy & Ho 2013). These outflows are also believed to contribute to the observed correlations between the black hole mass and the properties of the surrounding bulge (Ferrarese & Merritt 2000; Gebhardt et al. 2000). Additionally, quasar outflows have been proposed as potential mechanisms for active galactic nuclei feedback processes, including the termination of star formation in the interstellar medium and the regulation of accretion onto the black hole (Fabian 2012; King & Pounds 2015).
