Regulation of Star Formation Amidst Heating and Cooling in Galaxies and Galaxy Clusters
... The leading candidate is heating by an AGN (see reviews by Fabian (2012); McNamara &Nulsen (2012)). The mechanical energy output from an AGN is sufficient to offset cooling on large scales and thus prevent run- away ...
