Detection prospects for heavy WIMP dark matter near supermassive black holes, particularly in M31

The study investigates finding heavy WIMPs near supermassive black holes (SMBHs) like M31 using gamma-ray observations from the Cherenkov Telescope Array (CTA). By modeling DM density spikes around these SMBHs, the research suggests that M31 is a prime target. While CTA might probe TeV-scale WIMP masses under optimistic spike density scenarios, current estimates indicate that M31's center is below the detection threshold for this search.
