On the origin of possible deviation from the blackbody spectrum of the cosmic microwave background radiation - Inverse Compton hypothesis based upon the explosion scenario

Abstract

Possible deviation from the blackbody spectrum of the cosmic microwave background radiation at the Wien part is indicated by the rocket observation of Nagoya-Berkeley group. Here, the inverse Compton hypothesis is examined based upon the explosion scenario for galaxy formation. Allowed ranges of physical parameters for reproducing the observation are explored in relation to the isotropy of spectrum at the Rayleigh-Jeans part, the size of voids, and the X-ray background radiation.
