Unstable cosmic ray nuclei constrain low-diffusion zones in the Galactic disc

ABSTRACT Observations of the vicinity of a variety of galactic gamma-ray sources have indicated a local suppression of diffusivity of cosmic rays (CRs) by up to three orders of magnitude. However, the impact of these low-diffusion zones on global properties of CR transport is, however, only poorly u...
