• High‐density O+ in Earth's outer magnetosphere and its effect on dayside magnetopause magnetic reconnection 

      Fuselier, SA; Mukherjee, J; Denton, MH; Petrinec, SM; Trattner, K.J.; Toledo-Redondo, S; Andre, M; Aunai, N; Chappell, Charles Richard; Glocer, Alex; Haaland, S.; Hesse, Michael; Kistler, LM; Lavraud, B; Li, WY; Moore, T. E.; Graham, D; Tenfjord, Paul; Dargent, J.; Vines, Sarah K.; Strangeway, Robert J.; Burch, J. L. (Journal article; Peer reviewed, 2019)
      The warm plasma cloak is a source of magnetospheric plasma that contain significant O+. When the O+ density in the magnetosphere near the magnetopause is >0.2 cm‐3 and the H+ density is <1.5 cm‐3, then O+ dominates the ...
    • Quantification of Cold-Ion Beams in a Magnetic Reconnection Jet 

      Li, Yu-Xuan; Li, Wen-Ya; Tang, Bin-Bin; Norgren, C.; He, Jian-Sen; Wang, Chi; Zong, Qiu-Gang; Toledo-Redondo, S.; André, M.; Chappell, C.; Dargent, J.; Fuselier, S.A.; Glocer, A.; Graham, D.B.; Haaland, S.; Kistler, L.; Lavraud, B.; Moore, T.E.; Tenfjord, P.; Vines, S.K.; Burch, J. (Journal article; Peer reviewed, 2021)
      Cold (few eV) ions of ionospheric origin are widely observed in the lobe region of Earth’s magnetotail and can enter the ion jet region after magnetic reconnection is triggered in the magnetotail. Here, we investigate a ...
    • Results of the Electron Drift Instrument on Cluster 

      Paschmann, G; Quinn, Jack M.; Torbert, R.B.; McIllwain, C; Vaith, H; Haaland, S.; Matsui, Hiroshi; Kletzing, Craig A.; Baumjohann, W; Haerendel, G (Journal article; Peer reviewed, 2021)
      The electron drift instrument (EDI) on Cluster pioneered a new method of measuring electric fields, using a beam of electrons to sample the drift velocity over a km-scale gyro orbit. The technique is especially well suited ...
