Constraining Axion-Like Particles as a Dark Matter Candidate

We looked into the possibility of Dark Matter being comprised, at least in a percentage, of Axion Like Particles (ALPs). In this scenario, we modeled ALPs interacting with Cosmic Rays, high energy electrons, resulting in a final gamma ray flux of GeV energies. This process could explain the mysterious Galactic Center Gamma-Ray excess, which is the detected extra emission of gamma rays coming from the center of the galaxy from an unknown source.
