Abstract

Dark matter is invisible, but its presence is detected via its gravitational effect on stars and galaxies. One powerful way to study dark matter is by looking at “tidal streams” that originate from globular clusters. These are long, thin trails of stars that are pulled away from dense clusters of old stars as they orbit the Milky Way. Tidal streams of stars can have a variety of shapes and thicknesses, and they can…
