Dynamic and thermal processes regulate the structure of the multiphase interstellar medium (ISM), and ultimately establish how galaxies evolve through star formation. Thus, to constrain ISM models and better understand the interplay of these processes, it is of great interest to measure the thermal pressure (Pth) of the diffuse, neutral gas. By combining [C II] 158μm, H I, and CO data from 31 galaxies selected from the Herschel KINGFISH sample, we have measured thermal pressures in 534...[Show more]
