The Interaction of Successive Coronal Mass Ejections: A Review (2016, background): “This idea originated from a statistical study by Gopalswamy et al. (2002) which showed that the presence of a previous CME within 12 hours of a wide and fast CME greatly increases the probability that this second, fast CME is SEP-rich (Gopalswamy et al., 2002; Gopalswamy, 2004).”
Estimating the frequency of extremely energetic solar events, based on solar, stellar, lunar, and terrestrial records (2012, result): “Kahler et al. [1978] suggested that the type II shocks associated with SEP events were driven by CMEs, a suggestion that has found increasing support [Gopalswamy et al., 2002; Cliver et al., 2004; Gopalswamy et al., 2005].”
Coronal mass ejections, type II radio bursts, and solar energetic particle events in the SOHO era (2008, background): “Note that Ip≥1 pfu events include both major (Ip≥10 pfu) and minor (1 pfu≤Ip 10 pfu) SEP events (Gopalswamy et al., 2002).”
Type II radio bursts and energetic solar eruptions (2003, background): “There were 11 events with intensity between 1 and 9 pfu, which are known as minor SEP events [Gopalswamy et al., 2002], but they are much larger than the typical impulsive events [see e.”
The Two Sources of Solar Energetic Particles (2012, background): “Several authors have suggested that particle acceleration is enhanced by the presence of a previous CME or SEP event (Kahler, 2001; Gopalswamy et al., 2002, 2004; Cliver, 2006; Li et al. 2012).”
S/WAVES: The Radio and Plasma Wave Investigation on the STEREO Mission (2008, unknown): “Finally, these STEREO observations of the type II radio signatures may provide new insights into the origin and nature of solar energetic particles (SEPs) (Gopalswamy et al. 2002, 2005).”
Coronal Shocks and Solar Energetic Proton Events (2004, background): “Neither Cane & Stone (1984) nor Gopalswamy et al. (2002) investigated SEP associations by beginning with a sample of metric type II bursts.”
Numerical Simulation of the Interaction of Two Coronal Mass Ejections from Sun to Earth (2005, background): “However, a high correlation is found between CME interaction in the lower heliosphere and SEP-rich events (Gopalswamy et al. 2002, 2003).”
> 25 MeV Proton Events Observed by the High Energy Telescopes on the STEREO A and B Spacecraft and/or at Earth During the First ∼ Seven Years of the STEREO Mission (2014, background): “…particle acceleration by multiple shocks (e.g., Pomerantz and Duggal, 1974; Levy, Duggal and Pomerantz, 1976; Cliver and Kallenrode, 2001) or multiple CMEs (e.g., Gopalswamy et al., 2002; Gopalswamy et al., 2004; Li SOLA: multiscsep6_fin.tex; 24 March 2014; 14:42; p. 23 et al., 2012) to take place.”
A Global Picture of CMEs in the Inner Heliosphere (2004, background): “Although interactions among shocks and ejecta are known to happen in the heliosphere (Burlaga et al., 1987), SOHO images and Wind/WAVES dynamic spectra provided direct evidence for CME interactions very close to the Sun (Gopalswamy et al., 2001c; 2002a).”
Properties of Ground Level Enhancement Events and the Associated Solar Eruptions During Solar Cycle 23 (2012, background): “Lower frequency type II bursts are thus indicative of stronger shocks driven by more energetic CMEs and hence are generally observed in association with SEP events (Gopalswamy et al. 2002).”
Intensity variation of large solar energetic particle events associated with coronal mass ejections (2004, methodology): “The seed particles may originate from impulsive flares [Mason et al., 1999] or from preceding CMEs [Gopalswamy et al., 2002a].”
The Physical Processes of CME/ICME Evolution (2017, background): “Interest in this topic grew following this initial report (e.g., see Reiner et al. 2003), and from debates about the association of interacting CMEs with large solar energetic particle (SEP) events (Gopalswamy et al. 2002; Richardson et al. 2003).”
Solar flares, coronal mass ejections and solar energetic particle event characteristics (2016, background): “In addition, there is evidence that larger SEP events often result when a fast CME follows a slower CME (Gopalswamy et al. 2002).”
Coupled Hydromagnetic Wave Excitation and Ion Acceleration at an Evolving Coronal/Interplanetary Shock (2005, background): “Individual events may be more complex (Gopalswamy et al. 2002, for example, has suggested that some large eventsmay arise frommore than oneCME or shock).”
