  • The isotropy of the cosmic-microwave background is a measure of the homogeneity of the Universe at the epoch of last scattering, conventionally taken to be the epoch of recombination of the primeval plasma at a redshift zs ∼1,000. Here we report measurements of the isotropy at a wavelength of 3 cm. At the 95% confidence level, our results restrict departures from isotropy to < 5–7×10−4 on angular scales of ∼2−10°. The angular scale of our observations is of particular cosmological significance… CONTINUE READING
