Updating Highest redshift section

Someone with more editing skills than I should update the Highest redshift section of the article (current z=11), since a redshift of z=13.27 has been detected from HD1 (galaxy) (as of 07 April 2022) Thanks! zCryophoenix 21:47, 8 April 2022 (UTC)

English

I removed "Original Research" that, on the face of it, was, to me, obviously incorrect. I removed the phrase "perhaps indicating that up to that point its German equivalent, Rotverschiebung, was more commonly used." I doubt this very much, particularly in light of the preceding sentences in the same paragraph this phrase was in. The English language always adds the adjective in front of the noun. When the adjective-noun pair are in fact naming a particular thing a hyphen is used. E.g. red ball vs base-ball or basket-ball. Thousands of times the hyphen is dropped when the particular thing is perceived as distinct and in need of its own noun. In point of fact base-ball and basket-ball became baseball and basketball in the same decade as red-shift became redshift. This has absolutely happened in English since its inception 1,500 years ago.

Earliest use in print

This article states that "The earliest occurrence of the term red-shift in print (in this hyphenated form) appears to be by American astronomer Walter S. Adams in 1908". However, the listed citation does not appear to support that, and the OED specifically disagrees, stating that "The concept was described by W. S. Adams in 1908 in connection with the effect of the rotation of the sun on its spectral lines (Astrophysical Jrnl. 27 213–18), but the term redshift was not used. A 'shift towards the red' is mentioned in Astrophysical Jrnl. (1897) 5 210." The earliest use that OED offers is by Arthur Stanley Eddington in 'The mathematical theory of relativity', 1923. I'm loathe to start editing a featured article on which I'm very far from an expert, hence why I'm not tackling this myself - I don't want to inadvertently introduce an error.

Misplaced Pages:Unreviewed featured articles/2020/2004–2009

This article was reviewed as part of this drive - Misplaced Pages:Unreviewed featured articles/2020/2004–2009

I believe this article does not satisfy the Featured Article criteria and it will go to a Featured Article Review in due course if the article is not updated. A list of problems is noted below;

• There is a list in the lead
• The Measurement, characterization, and interpretation section has too few refs
• The Doppler effect section, too few refs
• The Mathematical derivation section is not encyclopaedic and not directly relevant
• The Extragalactic observations section has too few refs and unreferenced paragraphs
• The Effects from physical optics or radiative transfer section has too refs
• The Doppler blueshift section has an unreferenced list
