Talk:Terrestrial gamma-ray flash

Merged details from Lightning article
I am merging a bunch of details here from the Lightning article. They may not integrate very well, so feel free to edit boldly! Melchoir (talk) 07:12, 10 August 2012 (UTC)

20 MeV?
The lede says, "TGFs have been recorded to last 0.2 to 3.5 milliseconds, and have energies of up to 20 MeV." 20 MeV is the energy of an individual photon, known as "photon energy." The total energy of an entire gamma-ray burst would be something much bigger, possibly measured in some other units such as Joules. Just to put this into context, when people receive linac photon treatment for eye- or brain-cancer, the machine delivers photons with energies of 4-25 MeV. In gamma-ray astronomy, 30 MeV is the usual dividing line between LE (low-energy) and HE (high-energy) gamma rays. The point is, 20 MeV is a totally normal normal for an individual gamma ray (or "high-energy photon" as it is known in medicine). Zyxwv99 (talk) 23:29, 10 September 2014 (UTC)

Other research
Pretty much every single paragraph in the "Other research" is already covered in the appropriate sections in the main body of the article. It looks to me like almost all of it an go away. Thoughts? --Dan East (talk) 23:12, 27 January 2015 (UTC)

Are cosmic rays involved?
All three of the illustrations of proposed mechanisms show cosmic rays triggering the RREAs. However, the article text (including the captions for those illustrations) does not mention cosmic rays even once. So, are they involved or not? If they are, the text should mention them; if not, the illustrations shouldn't show them as apparently necessary. ← PointyOintment ❬t &amp; c❭ 06:03, 14 June 2020 (UTC)
