  • A ground-based polarimeter, PIQUE, operating at 90 GHz has set a new limit on the magnitude of any polarized anisotropy in the cosmic microwave background. The combination of the scan strategy and full width half-maximum beam of 024 gives broad window functions with lE = 211 and lB = 212 for the E- and B-mode window functions, respectively. A joint likelihood analysis yields simultaneous 95% confidence level flat band power limits of 14 and 13 μK on the amplitudes of the E- and B-mode angular… CONTINUE READING
