Cosmic Microwave Background  

In General > s.a. history of relativistic cosmology; observational cosmology; topological defects.
* Idea: A diffuse radiation that that has been around since about 380,000 years after the Big Bang, when the universe cooled down enough for nuclei and electrons to recombine, and the neutral matter became largely transparent to the thermal radiation that filled the universe.
* History: 1948, Theoretical idea discussed; 1965, Discovered by Penzias and Wilson of Bell Labs; 1989: COBE launched; 1992, Anisotropy reported by COBE with Δθ ≈ 7°; 1996, Plans for experiments down to Δθ ≈ 10'; 1999, plans for MAP and Planck orbiting detectors; 2000, Boomerang maps with 50 ≤ l ≤ 600 support inflation and flat space; 2001, Boomerang and DASI data show second and third peaks in angular distributions, WMAP launched; 2003, WMAP blows everybody away; 2006, WMAP 3-year results, and plans for Planck; 2009: Planck launched; 2013: Planck data release, anomaly recognized in fluctuations; 2014, The BICEP2 collaboration reported results on cmb polarization that could be a sign of gravitational waves, but the signal was later shown to be due to foreground dust.
* Temperature: Value T = 2.726 K, from COBE results [@ news pn(93)jan]; The spectrum looks almost exactly like a blackbody spectrum.
* Missions: COBE; WMAP (Wilkinson Microwave Anisotropy Probe, 2001-2010); Planck (launched in 2009, active until 2013).
