Seminar of the Day

Electron Energization in the Substorm Magnetotail: Insights from ELFIN and CIRBE Observations

Space Physics Seminar
Friday Feb 21 3:30p.m. - 4:30p.m.
Presented By:
Prof. Xiaojia Zhang - UT Dallas

Magnetic reconnection and the subsequent magnetic field reconfiguration, often referred to as the collapse of magnetic traps, are well-established mechanisms for charged particle acceleration in planetary magnetotails and solar flares. The efficiency of these mechanisms depends on various geometric and plasma characteristics, with the most reliable insights obtained from direct …
