Merging Cluster Collaboration: A Panchromatic Atlas of Radio Relic Mergers

Understand

Golovich et al.

• 2017b presents an optical imaging and spectroscopic survey of 29 radio relic merging galaxy clusters.
• In this paper, we study this survey to identify substructure and quantify the dynamics of the mergers.
• Using a combined photometric and spectroscopic approach, we identify the minimum number of substructures in each system to describe the galaxy populations and estimate the line of sight velocity difference between likely merging subclusters.
