Distribution of molecular gas in our Milky Way
In this ongoing project of my PhD, I try to use existing knowledge about the structure of our Milky Way to infer distances to the fitted emission line components from the Galactic Ring Survey (see project below). We use the Bayesian Distance Calculator tool (Reid et al. (2016)) to get distance solutions to the fitted components by folding in prior information, such as the rotation curve of our Milky Way, parallax measurements to high-mass star-forming regions, spiral arm positions determined from Galactic plane surveys, and distance solutions from the literature. This work will allow us to quantify the fraction of molecular gas located in spiral arms and to infer how important physical quantities change with Galactocentric distance.
