Talk:List of galaxy groups and clusters

Clarification
There's a garbled sentence in the intro text:
 * "In particulary clusters close to the Milky Way, tend to be classified at a smaller scale groups than more distant clusters."

I'm straightening this out to
 * "In particular, clusters close to the Milky Way tend to be classified as galaxy clusters even when they are much smaller than more distant clusters."

It's hard to tell exactly what the original sentence was supposed to mean, so if I didn't get it quite right, feel free to correct my correction. -- Reuben 21:28, 25 Jan 2005 (UTC)

Name
Shouldn't this be renamed to "List of galaxy clusters and groups" (or "List of galaxy groups and clusters")? There are many entries on the list that aren't normally considered clusters, such as the Local Group, etc. Ardric47 02:26, 20 March 2006 (UTC)

 * I would recommend redirecting to Virgo Cluster. Dr. Submillimeter 21:39, 8 June 2007 (UTC)

historical
apparently only 25 galaxy clusters were known in 1933 70.55.91.230 (talk) 14:00, 20 July 2008 (UTC)

Abell's 1958 cluster list uses 1900 dated coordinates and 1855 dated... I assume these are Basselian... 70.55.91.230 (talk) 14:32, 20 July 2008 (UTC)

2XMM J083026+524133
Is 2XMM J083026+524133 the most massive cluster, or the most massive cluster over redshift 1? There is a difference (ie. more massive clusters z < 1 ) 76.66.202.139 (talk) 13:05, 8 May 2009 (UTC)

Z-FORGE z=2.2 2012 cluster
I can't seem to find a location for the center in the discovery paper, it gives three overdensity centres, (10:00:15.753, +02:15:39.56), (10:00:18.380, +02:14:58.81), (10:00:23.552, +02:14:34.13), and has a discussion that this is possibly a proto-super-cluster, instead of a cluster, it does however say it is not a protocluster. ; so this could be placed as the most distant known cluster. (March 2012, taking over from the 2011 z=2.07 cluster, on our list) 70.24.248.211 (talk) 09:36, 9 April 2012 (UTC)

COSMOS-AzTEC-1 and SDSS J150243.09+111557.3
I recommend to add COSMOS-AzTEC-1 in a certain category (probably in the "Farthest protoclusters" section).

SDSS J150243.09+111557.3 with three black holes article here.
