visualizing the kinematics of the disk

My only research today was reading and signing off on a paper by Jason Hunt (Flatiron) about the kinematics of stars in the Milky Way disk. His innovation was to plot the stars in something akin to action-angle coordinates (guiding-center-position coordinates). It's a good space to look at spiral structure and other velocity substructure. And to compare to simulations. The visualizations in the paper are lovely.
