ANISOTROPY OF RELIC RADIATION IN THE RELICT-1 EXPERIMENT AND PARAMETERS OF GRAND UNIFICATION

We discuss new results of the data reduction of the space experiment R ELICT-1 (the investigation of the anisotropy of the cosmic microwave b ackground at 37 GHz). The anomalous signal is detected with 99% confid ence in a region with an area of about 1 sterad, centered at R.A.=1 h 30 m, Dec=-10-degrees (1=150-degrees, b=-70-degrees). The brightness t emperature of the signal is DELTAT=-71+/-43 muK with 90% confidence in cluding systematic errors. The nature of the signal cannot be explaine d by apparatus effects or by radio emission of known sources, there ar e reasons to believe that the signal is of cosmological origin. For a model of a cosmological signal with scale invariant spectrum, which is proposed by inflationary theory, we have estimated the quadrupole com ponent to be 6 x 10(-6) < DELTA T2/T < 3.3 x 10(-5) with 90% confidenc e including systematic errors, some main parameters of grand unificati on theory, and the nature of the contributors of dark matter in the Un iverse.
