Feedback is a key element of galaxy evolution, and the accretion of gas onto a central supermassive black hole (SMBH) is an important source of feedback. Modelling the energy released as an optically thick wind (with speed vw) allows observable relat... Read More about Dynamics of outflows driven by winds from supermassive black holes.
