  Coronal mass ejections (CMEs) are large clouds of magnetized plasma ejected
from the Sun, and are often associated with acceleration of electrons that can
result in radio emission via various mechanisms. However, the underlying
mechanism relating the CMEs and particle acceleration still remains a subject
of heated debate. Here, we report multi-instrument radio and extreme
ultraviolet (EUV) imaging of a solar eruption event on 24 September 2011. We
determine the emission mechanism of a moving radio burst, identify its
three-dimensional (3D) location with respect to a rapidly expanding EUV wave,
and find evidence for CME shocks that produce quasiperiodic acceleration of
electron beams.
