The winding arms of spiral galaxies are one of their most obvious features. By measuring how tightly the arms are wrapped, we can reveal clues about other components that are much harder to observe, such as dark matter content and central black hole mass. We aim to partner volunteers with AI in order to identify individual spiral arms in tens of thousands of galaxies, measure how tightly each arm is wound, and use those measurements to estimate these elusive properties. Doing so will help us better understand how galaxies similar to our own Milky Way form and evolve.
