Multi-Mission Observations of Relativistic Electrons and High-Speed Jets Linked to Shock Generated Transients
Savvas Raptis, Martin Lindberg, Terry Z. Liu +19
Shock-generated transients, such as hot flow anomalies (HFAs), upstream of planetary bow shocks, play a critical role in electron acceleration. Using multi-mission data from NASA's…
