Description
The Fermi Bubbles (FBs) are two large structures above and below the Galactic Plane. They are first discovered by Fermi-LAT and thought to be related to the jet or the wind from the Galactic center. In this work, we use more than 5 years of DAMPE photon data to analyze the FBs. We calculate the TS values of the FB lobes and the significance of its curved spectrum. The obtained spectral parameters are then compared with those from the Fermi-LAT. We also search for the emission from the Cocoon in the southeast part of FBs. Since the Galactic diffuse emission (GDE) model is a major source of systematic uncertainty, we switch to the GDE models calculated with Galprop and find its influence.
