Mark Reid studies Galactic structure using precise distances and motions of masers. The cited work combines trigonometric parallaxes of high-mass star-forming regions to map the Milky Way and constrain its rotation. This links direct angular measurements with a large-scale model of our Galaxy.[ref]
