CMZ gamma-ray luminosity profiles, computed using the model with realistic CR dynamics introduced in this paper. The luminosities are calculated by integrating the flux in the regions shown in the bottom right panel of Fig. 2. Left panel: gamma-ray profiles considering the CMZ as a disk, for all models shown in the left panels of Fig. 2. Right panel: gamma-ray profiles considering the CMZ as a ring, for the models shown in the top four right panels of Fig. 2. Black crosses denote the observed gamma-ray luminosity computed by H.E.S.S. Collaboration (2016) in the CMZ. Yellow squares, blue circles, gray diamonds and red triangles, represent the gamma-ray luminosity considering the NSC, NSC+Sgr A East, NSC+AC+QC, and NSC+Sgr A East+AC+QC, as CR sources, respectively.
