Question: There is a line that says,
"With Chandra X-ray Observatory structures like cold front, shock front, minihalo have also been found in many galaxy clusters." Is the reference to "Cold Front" a misprint? The link leads to a page about weather fronts, which seems to have nothing to do with astrophysics. — Preceding unsigned comment added by 173.48.33.218 ( talk) 03:09, 30 July 2012 (UTC)
The lead-in to this article states that clusters are the largest structures in the Universe. I got to this stub by starting with the Virgo Super cluster. Custers are usually components of super clusters which are components of the cosmological filaments which are the largest observed structures in the Universe. A cluster is smaller by many orders of magnitude. Remove of revise this terrible example of bad science information! 71.31.152.220 ( talk) 02:07, 29 August 2012 (UTC)
This source says that (at least some) galaxy clusters are in fact gravitationally bound: http://www.reuters.com/article/2014/09/03/us-space-galaxies-idUSKBN0GY2C820140903
This source implies it: http://www.vox.com/2014/9/4/6105631/map-galaxy-supercluster-laniakea-milky-way
Therefore i suggest we change the text saying that galaxy clusters are the largest gravitationally bound structures. Any objections?

Sounds incorrect to me. Elsewhere it states that LG AND VC are members og the same supercluster, be it Virgo SC or Laniakea. Asgrrr ( talk) 13:47, 29 May 2016 (UTC)
The article mentions intergalactic gas plasma several times, but does not discuss the composition of gas. What are the main constituents of this gas? It would be helpful if someone could add a brief description and possible link or source. Thanks! J Mark Morris ( talk) 19:55, 25 January 2019 (UTC)
Many galaxy articles on Wikipedia reference articles about intracluster light (ICL) but it is not mentioned here. If it was, we could redirect here. Some new more sensitive measuements have been made (and compared to dark matter estimates). Precision measurements of intracluster light suggest possible link to dark matter. It would be interesting to describe the ICL spectrum from different clusters. Is it distinct from the x-rays detected from the Intracluster medium ? - Rod57 ( talk) 00:59, 8 February 2021 (UTC)
