Diagram of star-formation-enhancing regions. Here we show a schematic of an AGN-driven outflow in a multiphase medium, with the wind filling a cavity surrounded by the shocked wind and shocked ISM. The three possible regions of star formation enhancement are named and indicated by arrows. Outflows can compress stationary clouds directly (for discussion see Sect. 5.1.1). Star formation can be sporadically enhanced in turbulent shear flow between the outflow and the galactic disc (see Sect. 5.1.2). Finally, outflows can fragment by themselves (see Sect. 5.1.3).
