Description
The nature of dark matter remains a major unresolved mystery in modern cosmology. In this work we explore the use of the MeerKAT Galaxy Cluster Legacy Survey in placing limits on the allowed annihilation cross-section for a variety of possible WIMP models. In so doing we demonstrate that MeerKAT is competitive with best available results in the literature, excluding WIMPs annihilating into b-quarks with masses below 800 GeV as viable cosmological dark matter. This unexpectedly makes galaxy clusters, with their large baryonic backgrounds, competitive with dwarf galaxy results.
