Extended Data Fig. 5: γ − ray diffuse emission intensity maps.

Following Fig. 4a and the calculations in Methods, we calculate the relative excess of the γ − ray flux density compared to patch R0 for γ − ray photons with (a) Eγ ≳ 1 GeV; (b) Eγ ≳ 10 GeV. The background area is selected in the yellow triangle in the northeast (the same as Patch R0 in Fig. 4a). The two lines are the edges of the eROSITA (solid) and Fermi (dashed) Bubbles.
