• Dynamic evolution of energetic outer zone electrons due to wave‐particle interactions during storms (2007, background): “As a consequence, EMIC waves, chorus, and hiss all become weaker [Bra¨ysy et al., 1998; Erlandson and Ukhorskiy, 2001; Meredith et al., 2003a, 2004], and plumes become narrower and eventually dissipate.”
• Precipitation of radiation belt electrons by EMIC waves, observed from ground and space (2008, background): “It is predicted that precipitation of relativistic electrons takes place near the dusk-side plasmapause, where EMIC waves are typically generated by ions with energies of tens of keV [Cornwall et al., 1970; Erlandson and Ukhorskiy, 2001; Meredith et al., 2003; Jordanova et al., 2008], and observat”
• Earth's Van Allen Radiation Belts: From Discovery to the Van Allen Probes Era (2019, background): “…are intense electromagnetic emissions, which typically occur in distinct frequency bands below ion cyclotron frequencies (Engebretson et al., 2002; Erlandson & Ukhorskiy, 2001; Fraser et al., 2010; Min et al., 2012; Usanova et al., 2008), and sometimes exhibit discrete, coherent structures (e.g.,…”
• Observation of two distinct, rapid loss mechanisms during the 20 November 2003 radiation belt dropout event (2006, background): “Such waves occur preferentially near the dusk sector, are very intense (1–10 nT) [ Erlandson and Ukhorskiy, 2001; Fraser and Nguyen, 2001], and can drive strong pitch angle diffusion [Albert, 2003; Summers and Thorne, 2003] of relativistic electrons and energetic protons.”
• Statistical analysis of relativistic electron energies for cyclotron resonance with EMIC waves observed on CRRES (2003, methodology): “[ 17 ] We require the total ion composition during storms, since EMIC waves are known to be most common at these times [ Braysy et al. , 1998; Erlandson and Ukhorskiy , 2001].”
• Timescales for radiation belt electron acceleration and loss due to resonant wave‐particle interactions: 2. Evaluation for VLF chorus, ELF hiss, and electromagnetic ion cyclotron waves (2007, background): “EMIC waves are intensified during magnetic storms [Fraser et al., 1996; Bra¨ysy et al., 1998; Erlandson and Ukhorskiy, 2001 ] with typical broadband amplitudes reaching values in the range 1–10 nT. A source of free energy for EMIC wave excitation is the anisotropic distribution of low-energy (� keV”
• Resonant scattering of outer zone relativistic electrons by multiband EMIC waves and resultant electron loss time scales (2015, background): “While EMIC waves are present during geomagnetically quiet periods, their occurrence and intensity increases during disturbed geomagnetic conditions [Bräysy et al., 1998; Erlandson and Ukhorskiy, 2001; NI ET AL.”
• EMIC wave activity during geomagnetic storm and nonstorm periods: CRRES results (2010, methodology): “This differs from Erlandson and Ukhorskiy [2001] who found, using DE‐1, that EMIC wave occurrences were 5 times higher during storms than nonstorm times in the magnetosphere.”
