  12. Why this Particular Merger is Significant • Using our newly developed method • 2-5 times further progressed than similar systems observed to date • Every great advance in our understanding of the physical universe is the direct result of understanding how things change with time Will Dawson: The Musket Ball: A Galaxy Cluster Merger in Unexplored Phase-space

  13. Merging Clusters are Important Astrophysical Probes • Evidence favoring dark matter over modified gravity • Constrain properties of dark matter • Most energetic events in the Universe • Potential source of extreme cosmic rays • Constrain matter-antimatter ratio N C S • (Credit: Simon Swordy (U.
