摘要

Supernova remnants are generally considered as the accelerators of the Galactic cosmic rays. The majority of supernovae have massive star progenitors and explode in a highly turbulent medium sustained by stellar winds and intense ionizing radiation in and around the parent stellar clusters. The early diffusion of cosmic rays after their injection in the turbulent medium and the potential confinement and reacceleration of the particles in this environment have escaped observations so far. Their propagation through gas and soft radiation fields can be traced in gamma rays. We will present an analysis of the Fermi Large Area Telescope (LAT) observations of the Cygnus X region: gamma-ray emission above 1 GeV reveals a cocoon of freshly-accelerated cosmic rays following the cavities carved by Cyg OB2 and other young stellar clusters. We will discuss the cocoon properties and the origin of the particles from the nearby r-ray bright supernova remnant r Cygni or the Cygnus superbubble.
