Description
Merging galaxy clusters can potentially constrain SIDM models in multiple ways,
with systematics complementary to those of other astrophysical probes. I will give an overview of Merging Cluster Collaboration activities to drive down the upper limit from merging clusters: new ways of discovering and selecting merging clusters; a weak lensing and spectroscopic survey of a substantial sample of merging clusters; and dynamical modeling to determine the merger phase. I will assess the potential for improved constraints with these techniques and place our work in context with other work in the field.
