Bio
Jason joined the Astrophysics Research Group in 2006. He holds a B.A.(Mod) in Theoretical Physics from Trinity College and is currently working on his PhD in "Multiscale Image Processing of Solar Coronal Mass Ejections". This work involves analysis of data from the twin spacecraft STEREO mission, and is in collaboration with scientists at NASA Goddard Space Flight Center, Maryland and the Naval Research Laboratory, Washington DC.
Research
Coronal Mass Ejections (CMEs) are large eruptions of plasma and magnetic field from the Sun which expand out into the solar system at hundreds of kilometers a second. They can impact the Earth's magnetic field, causing disruptions to satellite systems, GPS and telecommunication networks. The diffuse nature of CMEs observed by SOHO/LASCO and STEREO makes it difficult to identify their morphology and kinematics. We are therefore developing multiscale image processing techniques to study the detailed physics of CMEs. By automatically determining the CME front, its kinematics can be studied (height, velocity, acceleration) as well as its morphology (curvature, expansion, rotation).
