Cherenkov Telescope Array will test whether pulsars generate the Galactic Center gamma-ray excess

The GeV-scale gamma-ray excess observed from the region surrounding Galactic Center has been interpreted as either products of annihilating dark matter particles, or emission a large population faint and centrally-located millisecond pulsars. If pulsars are responsible for this signal, they should also produce detectable levels TeV-scale emission. In study, we employ template-based analysis simulated data in an effort to assess ability Cherenkov Telescope Array (CTA) detect constrain presence emission, providing new powerful means testing whether excess. We find that after even relatively brief observation Inner Galaxy, CTA will be able definitively rule out source Gamma-Ray Excess.
