Recognizing the fingerprints of the Galactic bar: a quantitative approach to comparing model (l,v) distributions to observation [PDF]

open access: yes, 2015
We present a new method for fitting simple hydrodynamical models to the (l,v) distribution of atomic and molecular gas observed in the Milky Way. The method works by matching features found in models and observations.
