Large-angle CMB fluctuations in Compact Open Universes
COBE-normalized simulated sky of CMB temperature in m004(-5,1)
compact hyperbolic model with
=0.9
(lower panels) versus
optimally filtered COBE DMR map (upper panels). The compact
space has volume equal to the volume of the last-scattering sphere. Although
closer to data than lower
models, the noticeable hot-spot features allow to rule out even this model.

COBE-normalized simulated sky of CMB temperature in m004(-5,1)
compact hyperbolic model with
=0.6
(lower panels) versus
optimally filtered COBE DMR map (upper panels). Sphere of last-scattering
encloses around 20 compact domains, each being a copy of the whole Universe.
COBE-normalized simulated sky of CMB temperature m004(-5,1)
compact hyperbolic model with
=0.3
(lower panels) versus optimally filtered COBE DMR map (upper panels).
Sphere of last-scattering encloses around 150 compact domains, each being a copy
of the whole Universe.
