LOFAR observations of a jet-driven piston shock in the low solar corona
The Sun produces highly dynamic and eruptive events that can drive shocks through the
corona. These shocks can accelerate electrons, which result in plasma emission in the form …

Propagation effects in quiet sun observations at meter wavelengths
Quiet Sun meterwave emission arises from thermal bremsstrahlung in the MK corona, and
can potentially be a rich source of coronal diagnostics. On its way to the observer, it gets …
