Title:
The effects of local stellar radiation and dust depletion on non-equilibrium interstellar chemistry |
Abstract: Interstellar chemistry is important for galaxy formation, as it determines
the rate at which gas can cool, and enables us to make predictions for
observable spectroscopic lines from ions and molecules. We explore two central
aspects of modelling the chemistry of the interstellar medium (ISM): (1) the
