• Electron losses from the radiation belts caused by EMIC waves (2014, background): “However, individual events with frequencies very close to the helium ion cyclotron frequency [Ukhorskiy et al., 2010] could scatter electrons at lower energies—but this would not be typical.”
• Effect of EMIC waves on relativistic and ultrarelativistic electron populations: Ground‐based and Van Allen Probes observations (2014, background): “In the cold plasma approximation, EMIC waves can interact with electrons below 1–2MeV only in regions of high plasma density [e.g., Ukhorskiy et al., 2010].”
• Van Allen probes, NOAA, GOES, and ground observations of an intense EMIC wave event extending over 12 h in magnetic local time (2015, background): “…have focused on helium band EMIC waves, which have been reported to dominate in the dusk sector in the statistical studies of EMIC waves noted above, some theoretical estimates indicated the effectiveness of hydrogen band EMIC waves as well [e.g., Summers et al., 2007b; Ukhorskiy et al., 2010].”
• On the storm‐time evolution of relativistic electron phase space density in Earth's outer radiation belt (2013, result): “Previous studies [e.g., Thorne et al., 2005; Selesnick, 2006; Tu et al., 2010; Ukhorskiy et al., 2010] have also concluded that during the main phase of some storms, losses of greater than ~0.5 MeV electrons to the atmosphere due to wave-particle interactions can be effective over timescales…”
• Circulation of Heavy Ions and Their Dynamical Effects in the Magnetosphere: Recent Observations and Models (2014, background): “Note that Loto’aniu et al. (2006) and Ukhorskiy et al. (2010) showed that EMIC waves right below the He+ gyrofrequency can interact with electrons having energies as low as 400 keV.”
• Global characteristics of electromagnetic ion cyclotron waves: Occurrence rate and its storm dependence (2013, background): “…are typically excited in the L-mode near the magnetic equator at frequencies below the local proton gyrofrequency [e.g., Bossen et al., 1976; Fraser and McPherron, 1982; Roux et al., 1982; Ludlow, 1989; Anderson et al., 1990; Meredith et al., 2003; Thorne et al., 2006; Ukhorskiy et al., 2010].”
• Resonant scattering of outer zone relativistic electrons by multiband EMIC waves and resultant electron loss time scales (2015, background): “…commonly adopted a parallel or quasi-parallel propagation assumption to determine the resonant scattering rates of EMIC waves [e.g., Summers and Thorne, 2003; Summers, 2005; Summers et al., 2007; Li et al., 2007;Ukhorskiy et al., 2010; Subbotin et al., 2010; Kersten et al., 2014;Ma et al., 2015].”
• Radiation belt dynamics: The importance of wave‐particle interactions (2010, methodology): “Observed properties of EMIC waves have been used to evaluate rates of quasi‐linear pitch‐angle scattering [Loto’aniu et al., 2006b; Ukhorskiy et al., 2010], and test particle scattering has been performed for large amplitude EMIC waves [Albert and Bortnik, 2009; Liu et al., 2010].”
• Earth's Van Allen Radiation Belts: From Discovery to the Van Allen Probes Era (2019, background): “…be larger than ~2 MeV (e.g., Jordanova et al., 2008; Meredith et al., 2003) but sometimes could extend to a few hundred keV when fpe/ fce is relatively large and wave frequency is close to the ion cyclotron frequency based on the cold plasma theory (e.g., Li et al., 2007; Ukhorskiy et al., 2010).”
• EMIC wave activity during geomagnetic storm and nonstorm periods: CRRES results (2010, background): “[2] Many studies have investigated electromagnetic ion cyclotron (EMIC) waves and their relationship with geomagnetic storms [Wentworth, 1964; Heacock and Akasofu, 1973; Mauk and McPherron, 1980; Daglis et al., 1999; Li et al., 2007; Engebretson et al., 2008a; Bortnik et al., 2008; Morley et al., 20”
