Discovery and Multi-Wavelength Analysis of a New Dissociative Galaxy Merger: The Champagne Cluster
Faik Bouhrik, Rodrigo Stancioli, David Wittman
We report the discovery of a new binary galaxy cluster merger, the Champagne Cluster (RM J130558.9+263048.4), using a detection method that identifies dynamically active clusters i…
