SCL126 in catalogs: R.A. 13h Dec. –3o, Distance: 240 Mpc
7 Abell clusters, 4 of them – X-ray clusters: Einasto et al. 1994, 1997, 2001
Shape and orientationVery compact core with X-ray clusters (collapsing supercluster? Gramann and Suhhonenko 2002)Very flatPerpendicular to the line-of-sight
2dF team, Colless et al. 2003

A1750
A1651, 1650:SZ effect(Udomprasert etal 2004)
Multiple mergersEvidence of a filament with X-ray clusters(Belsole etal 2004, Donelly etal 2001)
Imprints of such superclusters on CMB maps(SZ, RS effects, Rubino-Martin etal 2004)
SCL126 in 2dF
SCL126-like systems in ΛCDM model
Model M768: no supercluster of similar richness and high density core (One “SCL126 candidate”)?
RFoF = 20 h-1 Mpc RFoF = 24 h-1 Mpc
SCL 126
Very rich Very compact core with several X-ray clusters X-ray data: multiple merger events at present and in the pastCollapsing core? One of the first superclusters?
Problem to the ΛCDM model?
