Re the removal of the text about an archival search of "gamma rays from the Fermi Gamma-ray Space Telescope", and the edit summary "the Nature story specifically states that Fermi did not find the earlier flare" ( [4]): I think the Nature article says the Fermi team didn't find it. But the reference at [5], also cited by the Nature article, says that "a new analysis of Fermi-LAT data" was used in support of the view that "(TXS) is the only counterpart of all the neutrino emissions in the region and therefore the most plausible first non-stellar neutrino and, hence, cosmic ray source.". So it seems that some sort of reference to archival searhing of Fermi data is appropriate. But perhaps the experts here have a more nuanced view. ★NealMcB★ ( talk) 16:07, 16 July 2018 (UTC)
What does TXS stand for? Is it what the nickname "Texas Source" comes from? ★NealMcB★ ( talk) 17:33, 16 July 2018 (UTC)
Is there a sky map of the extreme (TEV) gamma ray sky that shows TXS 0506+056? ★NealMcB★ ( talk) 17:35, 16 July 2018 (UTC)
E.g. getting the Fermi blazar map integrated with WikiSky would be great. Note that this blazar can be easily found in one of the unnamed circles from the Fermi blazar map by matching the constellation version of that map with the data in the article and the border info at https://upload.wikimedia.org/wikipedia/commons/f/ff/Orion_IAU.svg Alternatively if someone can combine those images and re-map them on the constellation map and point to this blazar, it would be great. ★NealMcB★ ( talk) 17:54, 16 July 2018 (UTC)
This may be a stupid question, but how do we know it originated as a νμ? What about neutrino oscillation? -- ἀνυπόδητος ( talk) 08:39, 10 August 2018 (UTC)
"though no cosmic rays from TXS 0506+056 have been directly observed. " I thought that we can't directly observe cosmic ray sources since they are electricaly charged they are bent in the magnetic field of the galaxy. Is not one of the major motivations for neutrino astronomy to find the sources of cosmic rays, which they can directly observe since neutrinos are electraly neutral?

The current text says "it is about 1.75 gigaparsecs (5.7 billion light-years) from Earth". The cited source specifically states this as a luminosity distance. I think interpreting a luminosity distance as an actual distance is unwarranted. 74.69.160.254 ( talk) 08:04, 24 December 2022 (UTC)
