... In the currently favored cosmology, CDM, the formation of dark matter structures can be simply understood as interactions solely through gravitational forces: small dark matter haloes form first and then merge together to build up larger ones. ... It is believed that such a process could be the feedback from the Active Galactic Nucleus (AGN; a BH accreting matter and radiating with large luminosities, LAGN 109 - 1015 L ) onto the host galaxy. ...
