Cosmic Microwave Background Anisotropy  

In General > s.a. brane cosmology.
* Anisotropy: The cmb is very nearly isotropic; T/T 5 10–6 on scales 10°, from the correlation

c():= (T/T)(n1) (T/T)(n2)st avg = (1/4) 1 c1 P1(cos) .

* Peaks: For fixed , the "spectrum'' c1 is expected to have peaks, whose position, height and shape give us information on physical parameters (baryon density, Hubble constant, topological defects vs inflation, etc); The position of the first peak indicates that the universe is spatially flat.
* Preferred directions? 2007, An alignment ("axis of evil") has been reported between the quadrupole and octopole moments in the WMAP microwave sky survey, but its significance is still being debated.

Sachs-Wolfe Effect
* Idea: A contribution from changes in the 's 4-momentum due to density perturbations; Allows us to correlate features in the cmb to large-scale structure.
