The cooling radius of a cold dark matter halo is defined to be the time at which the cooling time tcool=tfreefalltcool=tfreefall
where
tcool=ρεΛ(T)n2H,tfreefall=3π32G(ρ+ρdm)−−−−−−−−−−−−√tcool=ρεΛ(T)nH2,tfreefall=3π32G(ρ+ρdm)
In the case where there is a spherical gas cloud gravitationally drawn towards a gaseous halo with the cooling radius rcool>rvirialrcool>rvirial, the spherical gas cloud cools rapidly and contracts rapidly, prohibiting hydrostatic equilibrium from taking place. The result is a spherical gas cloud collapsing by the free fall time tfreefalltfreefall.
What actually happens then in the event that the cooling radius rcoolrcool is smaller than the virial radius of the gaseous halo? What is the resulting dynamics?
