• Parameterization of radiation belt electron loss timescales due to interactions with chorus waves (2007, background): “For E > 100 keV the scattering rates are higher for the lower energy particles, consistent with previous studies [e.g., Horne et al., 2005a; Albert, 2005].”
• Three‐dimensional electron radiation belt simulations using the BAS Radiation Belt Model with new diffusion models for chorus, plasmaspheric hiss, and lightning‐generated whistlers (2014, background): “These waves play a dual role in radiation belt dynamics leading to both the acceleration and loss of relativistic electrons [Horne et al., 2005a, 2005b; Thorne et al., 2005b; Bortnik and Thorne, 2007].”
• Radiation belt dynamics: The importance of wave‐particle interactions (2010, background): “…flux enhancement in the outer radiation belt in association with sustained geomagnetic activity [Tsurutani et al., 2006] during the storm recovery [Horne et al., 2005b; Shprits et al., 2006a] and for the refilling of the electron slot between the inner and outer radiation belts during a storm…”
• Observation of two distinct, rapid loss mechanisms during the 20 November 2003 radiation belt dropout event (2006, background): “Chorus waves have been shown to significantly intensify with magnetic activity [Meredith et al., 2001] and cause pitch angle scattering which is peaked ata 50 –90 for 1MeVelectrons [Horne et al., 2005a, 2005b].”
• Science Goals and Overview of the Radiation Belt Storm Probes (RBSP) Energetic Particle, Composition, and Thermal Plasma (ECT) Suite on NASA’s Van Allen Probes Mission (2013, background): “…that interplanetary shocks can produce ‘prompt acceleration’ events and combinations of processes under extreme conditions can produce ‘slot-filling’ events; such observations provide highly-sensitive tests of our physical understanding through theory/model comparisons (e.g. Horne et al. 2005).”
• Space Weather Effects in the Earth’s Radiation Belts (2018, background): “Horne et al. (2005) and Shprits et al. (2006) have speculated that the erosion of the plasmasphere to low L could create temporary conditions that are conducive to local acceleration there.”
• Modeling the propagation characteristics of chorus using CRRES suprathermal electron fluxes (2007, background): “…responsible for controlling the dynamics of the relativistic radiation-belt electrons, since many of the theories of chorus acceleration and loss rely on the interaction between chorus waves and energetic particles at mid- and high- latitudes [Horne et al., 2005b; Thorne et al., 2005a, 2005b].”
• THEMIS analysis of observed equatorial electron distributions responsible for the chorus excitation (2010, background): “…understand the global distribution of chorus excitation and its effect on energetic radiation belt electrons [Meredith et al., 2001; Summers et al., 2002; Horne and Thorne, 2003; Horne et al., 2003b, 2005; Meredith et al., 2003; Albert, 2005; Li et al., 2007; Thorne et al., 2007; Li et al., 2009a].”
• Global simulation of magnetosonic wave instability in the storm time magnetosphere (2010, methodology): “For the strongest MS waves, the acceleration time scale of 1–2 days via electron Landau resonance is comparable to that due to whistler mode chorus waves [e.g., Horne et al., 2005; Li et al., 2007].”
• Three-dimensional simulations of outer radiation belt electron dynamics including cross-diffusion terms (2010, background): “Such substantial enhancement of flux has been regarded as the result of cyclotron wave‐particle interactions [Horne and Thorne, 1998; Summers et al., 1998, 2004, 2007a, 2007b; Roth et al., 1999; Summers and Ma, 2000; Horne et al., 2003a, 2005; L.

• Dependence of the quasi‐linear scattering rates on the wave normal distribution of chorus waves (2009, background): “ Horne et al. [2005] and Albert [2005] used Gaussian distributions similar to (2) with a peak power in the direction along the magnetic field, width Xw = 0.577, and cutoffs at Xmin = 0 and Xmax = 1. While only first-order resonance is possible for simulations with field-aligned waves, obliquely pro”
• Radiation Belt Environment model: Application to space weather nowcasting (2008, result): “work suggests that the timescale for acceleration is typically of the order of 1–2 d [Summers and Ma, 2000; Horne et al., 2005a, 2005b ], consistent with observations.”
• Discovery of very large amplitude whistler‐mode waves in Earth's radiation belts (2008, background): “Acceleration of electrons by low amplitude whistler-mode ‘chorus’ waves is currently accepted to be an important process in the outer belt [Summers et al., 1998; Roth et al., 1999; Summers and Ma, 2000; Meredith et al., 2001; Horne and Thorne, 2003; Horne et al., 2005; Albert and Young, 2005].”
