    • Direct observations of anomalous resistivity and diffusion in collisionless plasma 

      Graham, D.B.; Khotyaintsev, Yu. V.; André, M.; Vaivads, A.; Divin, A.; Drake, J.F.; Norgren, Astrid Elisabet Cecilia; Le Contel, Contel; Lindqvist, P.-A.; Rager, A.C.; Gershman, D.J.; Russell, C.T.; Burch, J.L.; Hwang, K.-J.; Dokgo, K. (Journal article; Peer reviewed, 2022)
      Coulomb collisions provide plasma resistivity and diffusion but in many low-density astrophysical plasmas such collisions between particles are extremely rare. Scattering of particles by electromagnetic waves can lower the ...

    • 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 ...

      Aghion, Stefano; Ahlen, O; Amsler, C; Ariga, A; Ariga, T; Belov, AS; Berggren, K; Bonomi, G; Braunig, P; Bremer, J; Brusa, RS; Cabaret, L; Canali, C; Caravita, R; Castelli, F; Cerchiari, G; Cialdi, S; Comparat, D; Consolati, G; Derking, H; Di, Domizio,S; Di, Noto,L; Doser, M; Dudarev, A; Ereditato, A; Ferragut, R; Fontana, A; Genova, P; Giammarchi, M; Gligorova, Angela; Gninenko, SN; Haider, S; Huse, Torkjell; Jordan, E; Jorgensen, LV; Kaltenbacher, T; Kawada, J; Kellerbauer, A; Kimura, M; Knecht, A; Krasnicky, D; Lagomarsino, V; Lehner, S; Magnani, A; Malbrunot, C; Mariazzi, S; Matveev, VA; Moia, F; Nebbia, G; Nedelec, P; Oberthaler, MK; Pacifico, Nicola; Petracek, V; Pistillo, C; Prelz, F; Prevedelli, M; Regenfus, C; Riccardi, C; Røhne, Ole Myren; Rotondi, A; Sandaker, Heidi; Scampoli, P; Storey, J; Vasquez, MAS; Spacek, M; Testera, G; Vaccarone, R; Widmann, E; Zavatarelli, S; Zmeskal, J (Peer reviewed; Journal article, 2014-07-28)
      The precise measurement of forces is one way to obtain deep insight into the fundamental interactions present in nature. In the context of neutral antimatter, the gravitational interaction is of high interest, potentially ...

    • Network community structure of substorms using SuperMAG magnetometers 

      Orr, L.; Chapman, S.C.; Gjerløv, Jesper; Guo, W. (Journal article; Peer reviewed, 2021)
      Geomagnetic substorms are a global magnetospheric reconfiguration, during which energy is abruptly transported to the ionosphere. Central to this are the auroral electrojets, large-scale ionospheric currents that are part ...

    • Optical emissions associated with narrow bipolar events from thunderstorm clouds penetrating into the stratosphere 

      Liu, Feifan; Lu, Gaopeng; Neubert, Torsten; Lei, Jiuhou; Chanrion, Olivier; Østgaard, Nikolai; Li, Dongshuai; Luque, Alejandro; Gordillo-Vázquez, Francisco J.; Reglero, Victor; Lyu, Weitao; Zhu, Baoyou (Journal article; Peer reviewed, 2021)
      Narrow bipolar events (NBEs) are signatures in radio signals from thunderstorms observed by ground-based receivers. NBEs may occur at the onset of lightning, but the discharge process is not well understood. Here, we present ...

    • A space hurricane over the Earth’s polar ionosphere 

      Zhang, Qing-He; Zhang, Yong-Liang; Wang, Chi; Oksavik, Kjellmar; Lyons, Larry R.; Lockwood, Michael; Yang, Hui-Gen; Tang, Bin-Bin; Moen, Jøran Idar; Xing, Zan-Yang; Ma, Yu-Zhang; Wang, Xiang-Yu; Ning, Ya-Fei; Xia, Li-Dong (Journal article; Peer reviewed, 2021)
      In Earth’s low atmosphere, hurricanes are destructive due to their great size, strong spiral winds with shears, and intense rain/precipitation. However, disturbances resembling hurricanes have not been detected in Earth’s ...

    • Sub-resolution contrast in neutral helium microscopy through facet scattering for quantitative imaging of nanoscale topographies on macroscopic surfaces 

      Eder, Sabrina Daniela; Fahy, Adam; Barr, Matthew G.; Manson, Joseph R.; Holst, Bodil; Dastoor, Paul C. (Journal article; Peer reviewed, 2023)
      Nanoscale thin film coatings and surface treatments are ubiquitous across industry, science, and engineering; imbuing specific functional or mechanical properties (such as corrosion resistance, lubricity, catalytic activity ...
