Interstellar Medium & Photoionized Gas

We have developed a three dimensional Monte Carlo photoionization code tailored for the study of H II regions and the low density ISM. The code is described and benchmarked against other codes in Wood, Mathis, & Ercolano (2004). This code was developed so we may analyze Ron Reynolds' WHAM data with three dimensional photoionization techniques. Joanna Barnes is a PhD student in St Andrews working on photoionization modeling of density grids from MHD simulations of a supernova driven urbulent ISM. Some recent talks on our work are presented here
