Brown et al. find a statistically significant deviation in the gamma-ray spectrum from Centuarus A's core as measured by the Fermi-LAT telescope. To account for the data may require a new mechanism for gamma-ray production and could constitute the first evidence of heavy dark matter particle clustering around black holes.
