    • AME: A Cross-Scale Constellation of CubeSats to Explore Magnetic Reconnection in the Solar–Terrestrial Relation 

      Dai, Lei; Wang, Chi; Cai, Zhiming; Gonzalez, Walter D.; Hesse, Michael; Escoubet, Philippe; Phan, Tai D.; Vasyliunas, Vytenis; Lu, Quanming; Li, Lei; Kong, Linggao; Dunlop, Malcolm W.; Nakamura, Rumi; He, Jianshen; Fu, Huishan; Zhou, M.; Huang, Shiyong; Wang, Rongsheng; Khotyaintsev, Yuri V.; Graham, D. B.; Retinò, Alessandro; Zelenyi, Lev; Grigorenko, Elena E.; Runov, Andrei; Angelopoulos, Vassilis; Kepko, Larry; Hwang, Kyoung-Joo; Zhang, Yongcun (Journal article; Peer reviewed, 2020)
      A major subset of solar–terrestrial relations, responsible, in particular, for the driver of space weather phenomena, is the interaction between the Earth's magnetosphere and the solar wind. As one of the most important ...

    • 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 ...

    • Impacts of Ionospheric Ions on Magnetic Reconnection and Earth's Magnetosphere Dynamics 

      Toledo-Redondo, S; Andre, M; Aunai, N; Chappell, Charles Richard; Dargent, Jeremy; Fuselier, S.; Glocer, Alex; Graham, D. B.; Håland, Stein Egil; Hesse, M.; Kistler, L. M.; Lavraud, B.; Li, W.; Moore, T. E.; Tenfjord, Paul Arne Riksheim; Vines, S. K. (Journal article; Peer reviewed, 2021)
      Ionospheric ions (mainly H+, He+, and O+) escape from the ionosphere and populate the Earth's magnetosphere. Their thermal energies are usually low when they first escape the ionosphere, typically a few electron volt to ...

    • 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 ...

    • Universality of Lower Hybrid Waves at Earth's Magnetopause 

      Graham, D. B.; Khotyaintsev, Yu V; Norgren, Astrid Elisabet Cecilia; Vaivads, Andris; Andre, M.; Drake, J. F.; Egedal, J.; Zhou, M.; Le Contel, O; Webster, J.M.; Lavraud, B.; Kacem, Imed; Génot, V.; Jacquey, C.; Rager, AC; Gershman, Daniel J; Burch, J. L.; Ergun, Robert E (Journal article; Peer reviewed, 2019)
      Waves around the lower hybrid frequency are frequently observed at Earth's magnetopause and readily reach very large amplitudes. Determining the properties of lower hybrid waves is crucial because they are thought to ...
