The Relikt-1 experiment - New results
Abstract
We present new results from reduction of data from the space experiment Relikt-1 (investigation of the anisotropy of the cosmic microwave background at 37 GHz). With 99 per cent confidence, an anomalous signal is detected in a region of area of about 1 sr, centred at RA = 1^h^30^m^, Dec = -10^deg^(l = 150^deg^, b = -70^deg^). The brightness temperature of the signal is {DELTA}T = -71+/-43 microK with 90 per cent confidence, including systematic errors. The nature of the signal cannot be explained by effects of the apparatus or by radio emission of known sources; there are reasons to believe that the signal has a cosmological origin. For a model of cosmological signal with scale- invariant spectrum, i.e. in terms of a power-law spectrum with n = 1, we estimate, for the rms, a quadrupole component of 6 X 10^-6^<{DELTA}T_2_/T<3.3X10^-5^ with 90 percent confidence, including systematic errors.
