Bulletin[edit]

Someone willing to update this article or the one for gamma rays may find this bulletin interesting: http://www.eurekalert.org/pub_releases/2005-12/nyu-pfe120905.php

Only 3.5 TeV. Not very high by today's standards. Zyxwv99 (talk) 02:05, 21 August 2014 (UTC)

The hyphen: gamma-ray vs gamma ray[edit]

Note that it is standard to hyphenate the adjective, but not the noun. Thus, "gamma-ray astronomy", but "high-energy gamma rays". (Similarly for X rays and cosmic rays, of course.) Wwheaton (talk) 08:32, 16 June 2008 (UTC)

Gamma-ray sensor technology[edit]

Could do with a brief summary or links to sensor technology/design. Rod57 (talk) 00:38, 10 September 2008 (UTC)

Incredible Distances[edit]

I took away the part of the introduction which was speaking about "incredible distances" since actually the gamma rays, due to the interaction with the Extra-Galactic Background Light are probably the kind of radiations that travels the shortest distance in the Universe and has therefore the shortest horizon.

Gamma ray uses that terminology and so does [NASA] "can observe them from distances of billions of light-years"... I think that is an "incredible distance" and [Here] "The incredible distance to this burst exceeded our greatest expectations". - Pmedema (talk) 07:41, 7 December 2010 (UTC)
How far gamma rays can travels depends largely on how energetic they are.
calculated mean free path of VHE, UHE, EHE, and THE gamma rays based on attenuation due to pair-production with EBL (extragalactic background light) and CMB (cosmic microwave background radiation) expressed in log10 megaparsecs (Mpc)
