Comment I don't know if this is a notable term, but it seems verifiable as having been used in academic articles: here is, for example, a 1976 ApJ paper on the Coma I galaxy cloud. --Mark viking (talk) 20:44, 22 September 2015 (UTC)[reply]
Article is quite vague and there are few papers I found which use this term. I don't know what a galaxy cloud is either; if it is a term for galaxy cluster then redirect to the galaxy cluster article. Otherwise, I'm not sure. --189.25.194.113 (talk) 03:47, 23 September 2015 (UTC)[reply]
Comment - I pinged Wikipedia:WikiProject Astronomy to see if anyone would be willing to come take a look. shoy (reactions) 20:42, 24 September 2015 (UTC)[reply]
I've searched through ADS and Scholar and couldn't find much other than the paper above. Lots of references to "Galactic clouds", referring to gas clouds in our galaxy, but not much else as far as I can see. Sam Walton (talk) 22:14, 24 September 2015 (UTC)[reply]
Comment - It is a term that never really caught on and is not commonly used today. You could make a case for notability, although the article does a poor job of it in its current state. If it is kept then the article should probably make clear that the term is essentially obsolete and doesn't fit well with modern knowledge of the large-scale structure of the universe.

Redirect to ~~galaxy cluster~~ galaxy groups and clusters. I did manage to find a handful of articles that use the term e.g. 2013MNRAS.429.2677K, but it's certainly not common. Mostly this gets confused with 'Galactic cloud', a molecular cloud within the Milky Way galaxy, or 'galactic clouds', molecular clouds in other galaxies. The use for structures bigger than galaxy groups but smaller than galaxy clusters is not widely used. No need for a separate article on it - one sentence in galaxy cluster would cover everything (although that article is itself disappointingly poor). Edit: on second thought, galaxy groups and clusters is probably a better target. Modest Genius ^talk 11:26, 25 September 2015 (UTC)[reply]

- It would probably be better to convert it into a disambiguation page, between galaxy groups and clusters (collection of galaxies, aka a cloud), galaxy supercluster (collection of galaxy groups and clusters, aka a cloud) and interstellar cloud (cloud in a galaxy); the subdivision of a supercluster should be part of galaxy supercluster. -- 70.51.202.113 (talk) 06:21, 28 September 2015 (UTC)[reply]

Redirect to galaxy groups and clusters per Modest Genius. Neither I nor my fellow editors have found much evidence of notability for this term independent of galaxy group or galaxy cluster, so redirect as a rough synonym seems the best option. I would be fine with the disambig page option, too, if folks thought it necessary. --Mark viking (talk) 18:11, 6 October 2015 (UTC)[reply]
