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 ... -
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 ... -
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 ... -
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 ... -
On the Presence and Thermalization of Cold Ions in the Exhaust of Antiparallel Symmetric Reconnection
Norgren, Astrid Elisabet Cecilia; Tenfjord, Paul Arne Riksheim; Hesse, Michael; Toledo-Redondo, Sergio; Li, Wenya; Xu, Yin; Kwagala, Norah Kaggwa; Spinnangr, Susanne Flø; Kolstø, Håkon Midthun; Moretto, Therese (Journal article; Peer reviewed, 2021)Using fully kinetic 2.5 dimensional particle-in-cell simulations of anti-parallel symmetric magnetic reconnection, we investigate how initially cold ions are captured by the reconnection process, and how they evolve and ... -
Solar Wind—Magnetosphere Coupling During Radial Interplanetary Magnetic Field Conditions: Simultaneous Multi-Point Observations
Toledo-Redondo, Sergio; Hwang, Kyoung-Joo; Escoubet, C. P.; Lavraud, Benoit; Fornieles, J.; Aunai, N.; Fear, R.C.; Dargent, J.; Fu, Huishan; Fuselier, Stephen A.; Genestreti, K.J.; Khotyaintsev, Yuri V.; Li, Wenya; Norgren, Astrid Elisabet Cecilia; Phan, Tai D. (Journal article; Peer reviewed, 2021)In-situ spacecraft missions are powerful assets to study processes that occur in space plasmas. One of their main limitations, however, is extrapolating such local measurements to the global scales of the system. To overcome ...
