Description
Galactic diffuse emission (GDE) is a major component of the GeV gamma-ray sky. The Fermi bubbles and the Galactic center excess are two distinct diffuse components that garnered significant attention. The DArk Matter Particle Explorer (DAMPE) is a space-borne high-energy particle telescope aiming at measuring cosmic rays and photons in a broad energy range. These two sources are suitable for observation with DAMPE due to their hard spectra. In this work, we adopt 9 years of the DAMPE photon data to analyze the two structures. The spectra over 2 GeV are derived and the morphologies are carefully studied. Systematic uncertainties associated with the background templates are also investigated. Finally, we compare our results with those of the Fermi-LAT.
