      Escoubet, C. P.; Hwang, KJ; Toledo-Redondo, Sergio; Turc, Lucile; Haaland, Stein; Aunai, N; Dargent, Jeremy; Eastwood, Jonathan P.; Fear, Robert C.; Fu, H.; Genestreti, Kevin; Graham, Daniel B.; Khotyaintsev, Yuri V.; Lapenta, G.; Lavraud, Benoit; Norgren, Cecilia; Sibeck, David G.; Varsani, Ali; Berchem, J.; Dimmock, A (Journal article; Peer reviewed, 2020-01-31)
      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 ...
    • Electron Acceleration and Thermalization at Magnetotail Separatrices 

      Norgren, Astrid Elisabet Cecilia; Hesse, Michael; Graham, Daniel B.; Khotyaintsev, Yuri V.; Tenfjord, Paul; Vaivads, Andris; Steinvall, Konrad; Xu, Yin; Gershman, Daniel J; Lindqvist, Per-Arne; Plaschke, Ferdinand; Burch, James L (Journal article; Peer reviewed, 2020)
      In this study we use the Magnetospheric Multiscale mission to investigate the electron acceleration and thermalization occurring along the magnetic reconnection separatrices in the magnetotail. We find that initially cold ...
    • Electron Heating by Debye-Scale Turbulence in Guide-Field Reconnection 

      Khotyaintsev, Yuri V.; Graham, Daniel B.; Steinvall, Konrad; Alm, Love; Vaivads, Andris; Johlander, Andreas; Norgren, Astrid Elisabet Cecilia; Li, Wenya; Divin, Andrey; Fu, Huishan; Hwang, Kyoung-Joo; Burch, James L; Ahmadi, Narges; Le Contel, Olivier; Gershman, Daniel J; Russell, Christopher T.; Torbert, R. B. (Journal article; Peer reviewed, 2020)
      We report electrostatic Debye-scale turbulence developing within the diffusion region of asymmetric magnetopause reconnection with a moderate guide field using observations by the Magnetospheric Multiscale mission. We show ...
    • Magnetic Reconnection in Three Dimensions: Modeling and Analysis of Electromagnetic Drift Waves in the Adjacent Current Sheet 

      Ergun, Robert E; Hoilijoki, Sanni; Ahmadi, N.; Schwartz, S.J.; Wilder, F.D.; Drake, James F.; Hesse, Michael; Shay, Michael A.; Ji, H.; Yamada, M; Graham, Daniel B.; Cassak, P.A.; Swisdak, M; Burch, J. L.; Torbert, R.B.; Holmes, JC; Stawarz, JE; Goodrich, Katherine A; Eriksson, S.; Strangeway, Robert J.; LeContel, O (Journal article; Peer reviewed, 2019)
      We present a model of electromagnetic drift waves in the current sheet adjacent to magnetic reconnection at the subsolar magnetopause. These drift waves are potentially important in governing 3‐D structure of subsolar ...
    • Mass‐loading the Earth's dayside magnetopause boundary layer and its effect on magnetic reconnection 

      Fuselier, Stephen; Trattner, K.J.; Petrinec, Steve M.; Denton, Mike; Toledo, Sergio P.A.; Andrè, M.; Aunai, N; Chappell, Charles Richard; Glocer, Alex; Haaland, Stein; Hesse, Michael; Kistler, Lynn M.; Li, Wenya; Moore, T. E.; Graham, Daniel B.; Alm, Love; Tenfjord, Paul; Dargen, Jeremy; Vines, Sarah; Nykyri, K.; Burch, James L; Strangeway, Robert J. (Peer reviewed; Journal article, 2019)
      When the interplanetary magnetic field is northward for a period of time, O+ from the high‐latitude ionosphere escapes along reconnected magnetic field lines into the dayside magnetopause boundary layer. Dual‐lobe reconnection ...
    • 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 ...
    • 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 ...
