Electron injections are critical processes associated with magnetospheric substorms, which deposit significant electron energy into the ionosphere. Although wave scattering of 1…
On the origin of "patchy" energy conversion in electron diffusion regions
Kevin J. Genestreti, Xiaocan Li, Yi-Hsin Liu +9
During magnetic reconnection, field lines interconnect in electron diffusion regions (EDRs). In some EDRs the reconnection and energy conversion rates are controlled by a steady ou…
