Summary: V. The Thermal
Beginning of the
-late 60's many groups made measurements of the intensity of the radiation and a
temperature collectively showing the spectrum is that of a BB (to 10% accuracy)
-1969 Tentative detection of a dipole anisotropy by Conklin, confirmed in 1971-1977 by
Henry, Wilkinson, and Smooth et al.
-1989 COBE (COsmic Background Explorer) launched, in 1990 first results confirming BB
-1992 COBE's detection of non-dipole anisotropies (nobel prize 2006 for PI's Smoot &
-2003 WMAP results on precission cosmology through CMB anisotropies, end mission 2010
CMB discovery time-line
-1947-1948 Gamow, Alpher and Hermans model of
nucleosynthesis predicts relic millimeter radiation, but
the models have difficulties to produce elements heavier
than Li, leads to its neglect.
-1965 Arno Penzias & Robert Wilson's serendipitous
