A flat Universe from high-resolution maps of the cosmic microwave background radiation

Nature, 2000
The blackbody radiation left over from the Big Bang has been transformed by the expansion of the Universe into the nearly isotropic 2.73 K cosmic microwave background.

Cosmic Microwave Background Radiation

Reviews of Modern Physics, 1999
Most astronomers and physicists now believe that we live in an expanding universe that evolved from an early state of extremely high density and temperature. Measurements of the spectrum and anisotropy of the cosmic microwave background radiation (CMBR) provide strong evidence supporting this picture. Today, the spectrum of the CMBR matches that of a 2.

Cosmic microwave background anisotropy

Nature, 1986
Current hypotheses for the origin of structure in the Universe lead to predictions of the amplitudes of anisotropies in the cosmic microwave background radiation. The dipole anisotropy is related to density fluctuations on large scales and to other determinations of our motion relative to distant galaxies.

Cosmic Microwave Background Fluctuations

2006
Several experiments have recently detected very low contrast, sub-horizon scale structures in the Cosmic Microwave Background (CMB). In the current cosmological model, these structures result from acoustic oscillations of the primeval plasma at recombination ( $z \sim 1100$ ).
