Cecilia Payne-Gaposchkin Medal and Prize. Schwartz is responsible for refuting the belief that cosmic rays trapped by self-excited turbulence within a supernova remnant cool irreversibly as the remnant expands. He has also significantly contributed to theoretical and observational analysis of collisionless shocks within the heliosphere.Steven J Schwartz - Personal webpage
/ref> His work on the "quasi-parallel shock", the component of the Earth's bow shock believed to be responsible for particle heating and acceleration, first theorized in the early 1990s, was later confirmed by observations from the Cluster spacecraft. Schwartz is the UK Project Scientist for the UK Cluster Science Centre, co-investigator for the PEACE electron instrumentation, CIS ion instrument and the FGM

magnetometer A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, ...
