A primary interest of the group is the theory and observation of solar flares. Solar flares are sudden, rapid brightenings in the solar atmosphere, associated with the restructuring of the coronal magnetic field. Our work on flares includes both theory and observations. We are also Co-I’s on NASA’s RHESSI mission, which produces flare X-ray and gamma-ray imaging and spectroscopy.
Flare plasma theory
We conduct theoretical and numerical investigations of the physics of flare plasmas, spanning plasma turbulence, electron transport and acceleration, wave interaction with the flare atmosphere, and the generation of X-ray, gamma-ray and radio emission.
We use data from multiple sources, including RHESSI, Hinode/EIS, the Solar Dynamics Observatory, to deduce the physical properties of flare plasmas in the corona and the chromosphere.
