Particle acceleration in superbubbles: MHD simulations and $\gamma$-ray signatures

ICRC 2023 Rapporteur: Status of the Gamma-ray Astronomy field

“…Since several years there has been an increase interest to investigate the origin of their VHE 𝛾-ray emission through spectral and morphological studies. There are several models manage to get particles up to PeV energies [60,61] and prospects to search for their signatures [62] not only in gamma rays, but also in neutrinos. For sources like the Cygnus Cocoon [63] it was shown that synchrotron emission limits the lepton contribution at the highest energies to be less than 25% emission beyond PeV in LHAASO data [64].…”
