Constraining topology with the CMB.
Abstract
The authors present a new data analysis method to study rectangular T3 "small universes" with one or two of its dimensions significantly smaller than the present horizon (referred to as T1- and T2-models, respectively). They find that the 4 year COBE/DMR data set a lower limit on the smallest cell size for T1- and T2-models of 3000h-1Mpc, at 95% confidence, for a scale invariant power spectrum.
