Galaxy Formation and “Feedback”
Supermassive black holes and their feedback effects in galaxy formation
... We have also carried out a suite of simulations with 2 × 384 3 particles in which the parameters of the black hole model were systematically varied by a factor of 4 each in the direction that seemed most interesting. ...
