Spatially Resolved Moving Radio Burst Associated with an EUV Wave

Zusammenfassung:Coronal mass ejections (CMEs) are large clouds of magnetized plasma ejected from the Sun and are often associated with the 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 2011 September 24. We determine the emission mechanism of a moving radio burst, identify its three-dimensional location with respect to a rapidly expanding EUV wave, and find evidence for CME shocks that produce quasiperiodic acceleration of electron beams.
