    • 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 ...

    • High-latitude cold ion outflow inferred from the Cluster wake observations in the magnetotail lobes and the polar cap region 

      Li, Kun; André, Mats; Eriksson, Anders; Wei, Yong; Cui, Jun; Håland, Stein Egil (Journal article; Peer reviewed, 2021)
      Cold ions with low (a few eV) thermal energies and also often low bulk drift energies, dominate the ion population in the Earth’s magnetosphere. These ions mainly originate from the ionosphere. Here we concentrate on cold ...

    • MMS Observations of Multiscale Hall Physics in the Magnetotail 

      Alm, Love; André, Mats; Graham, Daniel B.; Khotyaintsev, Yuri V.; Vaivads, Andris; Chappell, Charles Richard; Dargent, Jérémy; Fuselier, Stephen A.; Haaland, Stein; Lavraud, Benoit; Li, Wenya; Tenfjord, Paul; Toledo-Redondo, Sergio; Vines, Sarah K. (Journal article; Peer reviewed, 2019)
      We present Magnetospheric Multiscale mission (MMS) observations of Hall physics in the magnetotail, which compared to dayside Hall physics is a relatively unexplored topic. The plasma consists of electrons, moderately cold ...
