How black holes power galactic super-winds

When gas falls into a supermassive black hole, it liberates amounts of energy so vast as to be capable of ejecting much of a galaxy’s gaseous reservoir. Such black holes may thus cause the end of their own growth and that of their host galaxies. A new model developed at MPA now makes it possible to simulate winds accelerated by accreting black holes in galaxy evolution simulations in a physically accurate and validated way. By blowing dense gas from galactic nuclei, and by halting inward flows from the galactic halo, winds play a vital role in shaping the galaxy evolution.
