      When the supersonic solar wind encounters the Earth's magnetosphere a shock, called bow shock, is formed and the plasma is decelerated and thermalized in the magnetosheath downstream from the shock. Sometimes, however, due ...

      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 ...

      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 ...
    • Millisecond observations of nonlinear wave–electron interaction in electron phase space holes 

      Norgren, Astrid Elisabet Cecilia; Graham, Daniel B.; Argall, Matthew; Steinvall, Konrad; Hesse, Michael; Khotyaintsev, Yuri V.; Vaivads, Andris; Tenfjord, Paul Arne Riksheim; Gershman, Daniel J; Lindqvist, Per-Arne; Burch, James L; Plaschke, Ferdinand (Journal article; Peer reviewed, 2022)
      Electron phase space holes (EHs) associated with electron trapping are commonly observed as bipolar electric field signatures in both space and laboratory plasma. Until recently, it has not been possible to resolve EHs in ...
