The GHOSDT Simulations: II. Missing H${}_2$ in Simulations of a Self-Regulated Interstellar Medium

Alon Gurman, Chia-Yu Hu, Michael Y. Grudic +2

Observations in the Galaxy and nearby spirals have established that the HI-to-H${}_2$ transition at solar metallicity occurs at gas weight of $P_{\rm DE}/k_B\approx 10^4 \ \rm K \ cm…
