The Merging Cluster 1E0657-56

Overview

The cluster 1E0657-56 (z=0.296), commonly known as the bullet cluster, is a supersonic cluster merger occurring nearly in the plane of the sky. The unique properties of this system make it a powerful probe of fundamental physics and astrophysics. Members of our team have used the bullet cluster to demonstrate the existence of dark matter and constrain the dark matter self-interaction cross-section. Ongoing projects including determining the impact of shock front upon star formation, improving the lensing maps, and studying the properties of lensed background galaxies.
