Cosmological simulations fail to reproduce realistic galaxy populationswithout energy injection from active galactic nuclei (AGN) into theinterstellar medium (ISM) and circumgalactic medium (CGM); a process called`AGN feedback'. Consequently, observational work searches for evidence thatluminous AGN impact their host galaxies. Here, we review some of this work.Multi-phase AGN outflows are common, some with potential for significantimpact. Additionally, multiple feedback channels can be observedsimultaneously; e.g., radio jets from `radio quiet' quasars can injectturbulence on ISM scales, and displace CGM-scale molecular gas. However,caution must be taken comparing outflows to simulations (e.g., kinetic couplingefficiencies) to infer feedback potential, due to a lack of comparablepredictions. Furthermore, some work claims limited evidence for feedbackbecause AGN live in gas-rich, star-forming galaxies. However, simulations donot predict instantaneous, global impact on molecular gas or star formation.The impact is expected to be cumulative, over multiple episodes.
