Recent Progresses on the Gamma-Ray Observations of DAMPE

The DArk Matter Particle Explorer (DAMPE) is a space-borne high-energy particle detector launched on 17 December 2015. It can observe the $\gamma$-ray sky from $\sim 2$ GeV to 10 TeV with the acceptance at most $1800~\rm cm^2\,sr$. With over 7.5 years of continuous operation, DAMPE has surveyed the whole sky for about 15 times and collected more than 300,000 candidate photon events. In the last few years, the understanding of the payload has been improved and the instrumental response functions have been calibrated with the on-board data. Besides, progresses have been made on the $\gamma$-ray line search, point source detection, diffuse emission analysis, and transient source monitoring. In the talk and this accompanying proceeding, the latest results on these topics are reported.
