    • Bifurcated Current Sheet Observed on the Boundary of Kelvin-Helmholtz Vortices 

      Hwang, K.-J.; Dokgo, K.; Choi, E.; Burch, J.L.; Sibeck, D.G.; Giles, B.L.; Norgren, Astrid Elisabet Cecilia; Nakamura, T.K.M.; Graham, D.B.; Khotyaintsev, Y.; Shi, Q.Q.; Gershman, D.J.; Pollock, C.J.; Ergun, R.E.; Torbert, R.B.; Russell, C.T.; Strangeway, R.J. (Journal article; Peer reviewed, 2021)
      On May 5, 2017 MMS observed a bifurcated current sheet at the boundary of Kelvin-Helmholtz vortices (KHVs) developed on the dawnside tailward magnetopause. We use the event to enhance our understanding of the formation and ...

    • Electron Bernstein waves driven by electron crescents near the electron diffusion region 

      Li, Wenya; Graham, D. B.; Khotyaintsev, Yuri V.; Vaivads, Andris; André, Mats; Min, K.; Liu, K.; Tang, B.B.; Wang, C.; Fujimoto, K.; Norgren, Astrid Elisabet Cecilia; Toledo-Redondo, Sergio; Lindqvist, Per-Arne; Ergun, R.E.; Torbert, Roy B.; Rager, A.C.; Dorelli, J.C.; Gershman, D.J.; Giles, B. L.; Lavraud, B.; Plaschke, F.; Magnes, W.; Le Contel, Olivier; Russell, Christopher T.; Burch, J. L. (Journal article; Peer reviewed, 2020)
      The Magnetospheric Multiscale (MMS) spacecraft encounter an electron diffusion region (EDR) of asymmetric magnetic reconnection at Earth’s magnetopause. The EDR is characterized by agyrotropic electron velocity distributions ...

    • Lower-Hybrid Drift Waves Driving Electron Nongyrotropic Heating and Vortical Flows in a Magnetic Reconnection Layer 

      Chen, Li-Jen; Wang, Shan; Le Contel, Olivier; Rager, A.; Hesse, Michael; Drake, J. F.; Dorelli, J.; Ng, J.; Bessho, Naoki; Graham, D. B.; Wilson, Lynn B.; Moore, T. E.; Giles, B. L.; Paterson, W.; Lavraud, B.; Genestreti, K.; Nakamura, Rumi; Khotyaintsev, Yuri V.; Ergun, R.E.; Torbert, Roy B.; Burch, J. L.; Pollock, C.; Russell, Christopher T.; Lindqvist, Per-Arne; Avanov, Levon (Journal article; Peer reviewed, 2020)
      We report measurements of lower-hybrid drift waves driving electron heating and vortical flows in an electron-scale reconnection layer under a guide field. Electrons accelerated by the electrostatic potential of the waves ...

    • Spatial evolution of magnetic reconnection diffusion region structures with distance from the X-line 

      Oieroset, M; Phan, Tai D.; Ergun, R.E.; Ahmadi, N.; Genestreti, K.; Drake, J. F.; Liu, Y.; Haggerty, CM; Eastwood, JP; Shay, M.A.; Pyakural, P.; Haaland, Stein Egil; Oka, M; Goodbred, M; Eriksson, S; Burch, J. L.; Torbert, R; Khotyaintsev, Y; Russell, C. T.; Strangeway, R; Gershman, D.J.; Giles, B. L. (Journal article; Peer reviewed, 2021)
      We report Magnetospheric Multiscale four-spacecraft observations of a thin reconnecting current sheet with weakly asymmetric inflow conditions and a guide field of approximately twice the reconnecting magnetic field. The ...
