Query: Stochastic Electron Acceleration in Shell-Type Supernova Remnants   We study the stochastic electron acceleration by fast mode waves in the
turbulent downstream of weakly magnetized collisionless astrophysical shocks.
The acceleration is most efficient in a dissipative layer, and the model
characteristics are determined by the shock speed, density, magnetic field, and
turbulence decay length. The model explains observations of shell-type
supernova remnants RX J1713.7-3946 and J0852.0-4622 and can be tested by
observations in hard X-rays with the HXMT and NuSTAR or gamma-rays with the
GLAST.
