Visualizations


A selection of images, movies, and interactive tours made by me and my group, drawn from my talks and papers. Click an image or movie for the full-resolution version. Where I know who made a figure, the credit is given. Please ask if you would like to use something; the data behind many of these are public (ALMA-IMF, ACES, JWST).

Slide builds and animated transitions

These are the animated builds and transitions in my talks (recorded from the live slides), plus the interactive pages behind them.

What shape is the Galactic Center?
Ring, filled disk, spiral arms and nested orbits: the competing proposals for the 3D shape of the CMZ, built up one at a time.
Mapping the gas in 3D with moving stars (cartoon)
Stars on the near and far sides of the center move in opposite directions across the sky; a cloud dims the stars behind it, which locates the cloud along the line of sight.

Cloud tomography with proper-motion-based distances (full version)
The full interactive version of the cartoon: face-on view, position-velocity diagram, extinction and star counts along the cloud's sightline.
