A Localized Burst of Relativistic Electrons in Earth's Plasma Sheet: Low- and High-Altitude Signatures During a Substorm

Autor: Shumko, M., Turner, D. L., Ukhorskiy, A. Y., Cohen, I. J., Stephens, G. K., Artemyev, A., Zhang, X., Wilkins, C., Tsai, E., Gabrielse, C., Raptis, S., Sitnov, M., Angelopoulos, V.

Earth's magnetotail, and the plasma sheet embedded in it, is a highly dynamic region that is coupled to both the solar wind and to the inner magnetosphere. As a consequence of this coupling, the plasma sheet undergoes explosive energy releases in the

Tens to hundreds of keV electron precipitation driven by kinetic Alfv\'en waves during an electron injection

Autor: Shen, Y., Artemyev, A. V., Zhang, X. -J., Angelopoulos, V., Vasko, I., Turner, D., Tsai, E., Wilkins, C., Weygand, J., Russell, C. T., Ergun, R. E., Giles, B. L.

Electron injections are critical processes associated with magnetospheric substorms, which deposit significant electron energy into the ionosphere. Although wave scattering of $<$10 keV electrons during injections has been well studied, the link betw

Relativistic electron precipitation by EMIC waves: importance of nonlinear resonant effects

Autor: Grach, Veronika S., Artemyev, Anton V., Demekhov, Andrei G., Zhang, Xiao-Jia, Bortnik, Jacob, Angelopoulos, Vassilis, Nakamura, R., Tsai, E., Wilkins, C., Roberts, O. W.

Relativistic electron losses in Earth's radiation belts are usually attributed to electron resonant scattering by electromagnetic waves. One of the most important wave mode for such scattering is the electromagnetic ion cyclotron (EMIC) mode. Within

The Electron Loss and Fields Investigation with a Spatio-Temporal Ambiguity-Resolving option (ELFIN-STAR, or simply: ELFIN) mission comprises two identical 3-Unit (3U) CubeSats on a polar (~93deg inclination), nearly circular, low-Earth (~450 km alti
