Detecting the B-mode Polarisation of the CMB with Clover
C. E. North, B. R. Johnson, P. A. R. Ade +41
We describe the objectives, design and predicted performance of Clover, which is a ground-based experiment to measure the faint ``B-mode'' polarisation pattern in the cosmic microw…
The 21cm angular-power spectrum from the dark ages
Antony Lewis, Anthony Challinor
At redshifts z >~ 30 neutral hydrogen gas absorbs CMB radiation at the 21cm spin-flip frequency. In principle this is observable and a high-precision probe of cosmology. We calcula…
CLOVER - A new instrument for measuring the B-mode polarization of the CMB
A. C. Taylor, A. Challinor, D. Goldie +11
We describe the design and expected performance of Clover, a new instrument designed to measure the B-mode polarization of the cosmic microwave background. The proposed instrument…
Anisotropies in the Cosmic Microwave Background
Anthony Challinor
The linear anisotropies in the temperature of the cosmic microwave background (CMB) radiation and its polarization provide a clean picture of fluctuations in the universe some 370…
Estimating the bispectrum of the Very Small Array data
Sarah Smith, Graca Rocha, Anthony Challinor +30
We estimate the bispectrum of the Very Small Array data from the compact and extended configuration observations released in December 2002, and compare our results to those obtaine…
Detecting magnetic CMB polarization on an incomplete sky
Antony Lewis, Anthony Challinor, Neil Turok
The full sky cosmic microwave background polarization field can be decomposed into `electric' and `magnetic' components. Working in harmonic space we construct magnetic variables t…
