Energy and fluxes of thermal runaway electrons produced by exponential growth of streamers during the stepping of lightning leaders and in transient luminous events (2011, background): “In addition to these space‐based measurements, X‐ray and gamma ray bursts have also been observed recently during natural and rocket‐triggered lightning discharges [Moore et al., 2001; Dwyer et al., 2003, 2004a, 2004b, 2005; Saleh et al., 2009].”
Monte Carlo model for analysis of thermal runaway electrons in streamer tips in transient luminous events and streamer zones of lightning leaders (2006, background): “: MONTE CARLO MODEL OF THERMAL RUNAWAY ELECTRONS formation of high-energy electron fluxes needed to explain the recently observed X-ray [Moore et al., 2001; Dwyer et al., 2003, 2004a, 2004b, 2005] and gamma ray [Fishman et al., 1994; Smith et al., 2005] bursts associated with thunderstorm activity.”
Source mechanisms of terrestrial gamma‐ray flashes (2008, background): “It also will be shown that the most likely TGF source mechanisms involve either a recently introduced mechanism called relativistic feedback [Dwyer, 2007] or the energetic particle emission from lightning leaders or streamers, similar to the energetic radiation observed on the ground in association ”
High-Energy Atmospheric Physics: Terrestrial Gamma-Ray Flashes and Related Phenomena (2012, background): “The discovery that both natural and triggered lightning discharges emit x-rays (Moore et al. 2001; Dwyer et al. 2003) demonstrated that some kinds of discharges in air produce high-energy electrons traveling close to the speed of light and having energies of at least hundreds of keV.”
A fundamental limit on electric fields in air (2003, background): “The existence of runaway breakdown seems likely given recent observations of energetic radiation associated with natural and triggered lightning, thunderstorms and redsprites [Moore et al., 2001; Dwyer et al., 2003; Parks et al., 1981; Eack et al., 1996; Fishman et al., 1994].”
A comparison between Monte Carlo simulations of runaway breakdown and terrestrial gamma‐ray flash observations (2005, background): “[3] In addition to spacecraft observations of TGFs, X-ray and gamma-ray emission has been measured from thunderstorms and from natural and triggered lightning [Eack et al., 1996; Moore et al., 2001; Dwyer et al., 2004a; Dwyer et al., 2005] Although the thunderstorm and lightning X-ray emission almos”
Lightning mapping observation of a terrestrial gamma‐ray flash (2010, background): “, 2006; Dwyer, 2008] and ground observations [Moore et al., 2001; Dwyer et al., 2004] of lightning‐produced energetic radiation in excess of 1 MeV.”
Recent advances in theory of transient luminous events (2010, background): “observations of X rays from relatively compact regions of space associated with steps of negative lightning leaders [Moore et al., 2001; Dwyer et al., 2005] and theoretical”
X‐ray bursts associated with leader steps in cloud‐to‐ground lightning (2005, result): “[15] The observations reported here confirm the previous findings by Moore et al. [2001] that natural negative lightning produces energetic radiation during the stepped leader phase.”
A closer examination of terrestrial gamma‐ray flash‐related lightning processes (2010, result): “During this period, the IC flashes are characterized by stepped‐leader processes [Shao and Krehbiel, 1996], and it is possible the TGFs were associated with the steps, similar to what is observed for CG stepped leaders [ Moore et al., 2001; Dwyer et al., 2003, 2005].”
The physics of streamer discharge phenomena (2020, background): “They appear in terrestrial gamma-ray flashes (TGFs) observed from space [189, 190], in lightning leaders approaching ground [191] or in long lasting gamma-ray glows measured above thunderclouds [192].”
A ground level gamma‐ray burst observed in association with rocket‐triggered lightning (2004, background): “Moore et al. [2001] also reported gamma-ray emission, measured on a high mountain, associated with stepped leaders from nearby lightning strikes.”
The physics of lightning (2014, background): “[170] reported intense energetic radiation during the stepped leader phase of negative natural cloud-to-ground lightning strikes on the mountains in New Mexico.”
