Cosmic microwave background anisotropy data correlation in WMAP and Relikt-1 experiments


Space Research Institute, Russian Academy of Sciences, Profsoyuznaya str. 84/32, Moscow, 117997, Russian Federation

A comparison is made of cosmic microwave background anisotropy data obtained from the WMAP satellite in 2001 — 2006 and from the Relikt-1 satellite in 1983 — 1984. It is shown that low-temperature area found by Relikt-1 is the location of the “coldest spot” of the WMAP radiomap. The mutual correlation of the two datasets is estimated and found to be positive for all sky regions surveyed. The conclusion is made that with the 98 probability, the Relikt-1 experiment had detected the same signal that was later identified by WMAP. A discussion is given of whether the Relikt-1 experiment parameters were chosen correctly.
