The gamma Cygni Supernova Remnant at the Highest Energies

Supernova remnants (SNRs) have long been thought to be the main source of Galactic Cosmic Rays up to PeV energies, and many of them have been shown to accelerate particles to very high energies. But which of them do indeed accelerate a significant number of protons and nuclei? And up to which energies can they accelerate these particles? Non-thermal photon emission, especially in the X-ray and gamma-ray range, is of crucial help in answering these questions.

This presentation will focus on multi-wavelength observations of the Cygnus region, a star-forming region including the gamma Cygni supernova remnant, a middle-aged SNR in the Cygnus region. We will use the VHE gamma-ray emission measured by the High-Altitude Water Cherenkov (HAWC) gamma-ray observatory as well as measurements from other instruments to obtain information about the underlying particle populations producing this emission.
