Latest Advancements on Cosmic Ray Carbon and Oxygen with the DAMPE Space Mission
The Dark Matter Particle Explorer (DAMPE), is a space–borne detector designed for precise Galactic Cosmic Ray (GCR) studies in a wide energy range (up to a few hundreds of TeV), along with detailed measurements of high–energy gamma–rays and indirect searches of Dark Matter (DM). The satellite was successfully launched into a sun–synchronous orbit at 500 km, on December 17th 2015 and has been successfully taking data ever since. DAMPE can provide valuable insights on the energy spectra of medium mass nuclei (CNO group) with exceptional resolution. In this work, the latest advancements regarding the spectral measurement of carbon and oxygen nuclei, will be presented, along with additional insights on the C/O flux ratio and the collective CNO flux, with 9 years of DAMPE flight data. Said results are crucial in deciphering distinct features across all spectra, complimented by a significant extension into the multi-TeV/n region, with great accuracy.
