Phenomenologicalmodels of cosmic-ray (CR) transport in theMilkyWay (MW) can reproduce a wide range of observations assuming that CRs scatter off of a roughly Kolmogorov spectrum of turbulent magnetic field fluctuations. We study the extent to which such phenomenological models can be reconciledwith current microphysical theories of CR transport, specifically selfconfinement due to the streaming instability and/or extrinsic turbulence due to a cascade of fast modes.We show that on their own… Expand
