ABSTRACT
We investigate the possibility of using a flat-fold beam steering mirror for a cosmic microwave background B-mode experiment. An aluminium flat-fold mirror is found to add ∼0.075% polarization, which varies in a scan synchronous way. Time-domain simulations of a realistic scanning pattern are performed, and the effect on the power-spectrum illustrated, and a possible method of correction applied.

    The Cosmic Microwave Background (CMB) provides us with a window on the early universe through which we are starting to see a great deal of detail. The recent BOOMERANG and MAXIMA results have given the first high-resolution wide-area maps of CMB fluctuations, and along with them the first...

    The Cosmic Background Imager (CBI) is an instrument designed to measure intrinsic anisotropies in the cosmic microwave background (CMB) on angular scales from about 3 arc minutes to one degree (spherical harmonics of ℓ ∼ 4250 to ℓ &sim 400). The CBI is a 13 element...

    We show that including the recoil upon scattering in the Ly- α line can lead to a noticeable acceleration of the primordial hydrogen recombination. Thus, for example, for the ΛCDM model, the decrease in the degree of ionization exceeds 1% at redshifts z = 800–1050, reaching...

    We report the first results from the BOOMERanG experiment, which mapped at 90, 150, 240 and 410 GHz a wide (3%) region of the microwave sky with minimal local contamination. From the data of the best 150 GHz detector we find evidence for a well defined peak in the power spectrum of temperature...

    We present the constraints on isocurvature fluctuations for a flat universe implied by the Boomerang and Maxima-1 data on the anisotropy of the cosmic microwave background.

    We discuss the status of the data obtained from the first two flights of the MAXIMA balloon-borne experiment. MAXIMA is sensitive to CMB fluctuations on angular scales from 10 arcmin to 5 degrees. The instrument uses a 16 element bolometric array with 3 frequency bands centered at 150, 240, and...
