<Martin Rees> develops theoretical accounts of cosmic structure. In a 1978 paper with <Simon White>, he separated the assembly of extended dark haloes from the dissipative concentration of luminous material within them.
Collisionless matter can build a large gravitationally bound halo, while <gas> can lose <energy> through <radiative cooling> and settle into a much denser luminous component. Their two-stage model connected the characteristic sizes and <luminosities> of <galaxies> to the cooling of <gas> inside a hierarchically assembled dark structure. It made the different physical behavior of the components central to the explanation.<Core condensation in heavy halos by Simon D. M. White and Martin J.
