Mark G. Wolfire co-authored models of the cold neutral medium and warm neutral medium within the interstellar medium. The analysis calculated the range of pressure over which these gas phases can coexist in thermal equilibrium.
The pressure range depends on environmental inputs such as the radiation field and composition. Connecting the allowed equilibria to Galactic conditions explains why a single temperature is inadequate for describing much of the neutral interstellar gas, and why radiative cooling must be considered together with energy input.[ref]
