Tuning in the Radio Sun

Slides from seminar given at the Netherlands Institute for Radio Astronomy (ASTRON) on November 29, 2013.

Abstract: Cosmic rays and solar energetic particles may be accelerated to relativistic energies by shock waves in astrophysical plasmas. On the Sun, shocks and particle acceleration are often associated with the eruption of magnetized plasmoids, called coronal mass ejections (CMEs). However, the physical relationship between CMEs and shock particle acceleration is not well understood. In this talk, I will show how extreme ultraviolet, radio and white-light images can be used to study CME-induced shocks and associated phenomena such as large-scale coronal waves. I will also show how LOFAR is giving a new insight into our understanding of electron acceleration in the solar corona.
