“…Among DAMPE recent results are the measurements of proton [13], helium [14] and electron/positron [15] fluxes. Preliminary results on 𝛾-ray observations were also presented [16]. These studies show interesting spectral features which help to push our understanding of the CR astrophysics and constrain the dark matter models [17][18][19].…”

A: DAMPE is a space-borne experiment for the measurement of the cosmic-ray fluxes at energies up to around 100 TeV per nucleon. At energies above several tens of TeV, the electronics of DAMPE calorimeter would saturate, leaving certain bars with no energy recorded. In the present work we discuss the application of machine learning techniques for the treatment of DAMPE data, to compensate the calorimeter energy lost by saturation.

The DArk Matter Particle Explorer (DAMPE) is well suitable for searching for monochromatic and sharp γ-ray structures in the GeV−TeV range thanks to its unprecedented high energy resolution. In this work, we search for γ-ray line structures using five years of DAMPE data. To improve the sensitivity, we develop two types of dedicated data sets (including the BgoOnly data which is the first time to be used in the data analysis for the calorimeter-based gamma-ray observatories) and

The Dark Matter Particle Explorer (DAMPE) is a satellite-borne, calorimetric type, high-energyresolution space cosmic ray and gamma-ray detector. It operates stably in space for more than three years since its launch in December, 2015. Precise measurements of the total electron plus positron spectrum and the proton spectrum in wide energy ranges have been obtained, which are expected to shed new light on our understanding of the cosmic ray origin and the nature of dark matter particles. The current status of the mission and its latest physical results will be presented.
