Gas temperature as a function of position within the cloud. Each panel corresponds to a different dust coagulation model, as labeled. The black curve shows the dust temperature, as determined from the radiative transfer model. The blue and red curves show the gas temperature assuming the high and low CR ionization rates, respectively, from Padovani et al. (2018). The solid lines are the full cooling model, and the dashed lines correspond to the dust-only cooling model in Ivlev et al. (2019).
