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 orientation
Very compact core with X-ray clusters
(collapsing supercluster? Gramann and
Suhhonenko 2002) Very flat Perpendicular to the
line-of-sight
SCL126 in LCRS -3o slice

SCL126 in 2dF
A1651, 1650 SZ effect (Udomprasert etal 2004)
A1750
Multiple mergers Evidence 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-like systems in ?CDM model
RFoF 20 h-1 Mpc
RFoF 24 h-1 Mpc
Model M768 no supercluster of similar richness
and high density core
(One SCL126 candidate)?

SCL 126
Very rich Very compact core with several X-ray
clusters X-ray data multiple merger events
at present and in the past Collapsing core?
One of the first superclusters? Problem to
the ?CDM model?
