Outflows are a ubiquitous feature of active galactic nuclei (AGN), spanning multiple gas phases, from highly ionised to molecular, and occurring in both low- and high accretion systems. These outflows are central to the AGN feedback paradigm, believed to regulate star formation and establish the observed correlations between supermassive black holes (SMBHs) and their host galaxies. Yet, the mechanisms driving these outflows remain under debate.
