Observational Constraints of 30–40 GeV Dark Matter Annihilation in Galaxy Clusters
Table 1
The scale radius (in Mpc), the scale density (in Mpc), -factor (in ), the gamma-ray flux from cosmic ray emission [13–15], the observed gamma-ray flux upper limits (95% CL) [13], and the calculated upper limits (95% CL) of the annihilation cross section ( and ) for A2877 and Fornax. All the units for the gamma-ray flux and annihilation cross section are in cm s and cm s, respectively.
