The heat input due the supernovae also leads to a net pressurisation of the ISM, such that its effective equation of state becomes stiffer than isothermal.
Is AGN feedback necessary to form red elliptical galaxies?
In principle, the solution to this problem should be provided by a suitable scheme of gas heating which regulates star formation, while maintaining pressurised gas in the hot phase.
Thermodynamical properties of the ICM from hydrodynamical simulations
SN feedback only provides disk pressurisation.

However, the theoretical situation still remains unclear, and FS-nesting as well as strong electron-phonon views are still claimed to be the instigators of CDW order and SC in pressurised or doped systems[10 ].
Preformed Excitons, Orbital Selectivity, and Charge-Density-Wave Order in 1T-TiSe_2
This effect is comparable to the Jeans’ criterion for the minimal mass required for a pressurised perturbation to collapse.
