PDFs of hydrogen number density as a function of galactocentric radius after 0.5 Gyr of evolution with or without including H2 cooling in the simulations for αfb = 1% and alternative star-formation parameters. Left: runs with nHmin = 10-1 cm-3 and c = 0.01. Right: runs with nHmin = 101 cm-3 and c = 0.1. Horizontal black line: threshold density for star formation.
