Description
Since its discovery by the Fermi-LAT space telescope, the galactic centre gamma-ray excess (GCE) has been the subject of intensive investigation in high-energy astrophysics. In this presentation, I will share progress on a current effort to model the GCE and determine if the Cherenkov Telescope Array Observatory (CTAO) will be able to distinguish between two prevalent hypotheses of the GCE emission: dark matter, or millisecond pulsars (MSPs). Our preliminary results of this investigation seem to suggest that CTAO may have sufficient performance to reveal features in the spatial distribution of gamma-ray emission that can strongly test a MSP scenario vs. dark matter. Hence, the CTAO could be the key to improving our current understanding of dark matter.
