Effects of boosting on extragalactic components: methods and statistical studies
William R. Coulton, Sydney Feldman, Karime Maamari +3
In this work we examine the impact of our motion with respect to the CMB rest frame on statistics of CMB maps by examining the one-, two-, three- and four- point statistics of simu…
Covariant transverse-traceless projection for secondary gravitational waves
Atsuhisa Ota, Hayley J. Macpherson, William R. Coulton
Second-order tensor modes induced by nonlinear gravity are a key component of the cosmological background of gravitational waves. A detection of this background would allow us to p…
The parity-odd Intrinsic Bispectrum
William R. Coulton
At linear order the only expected source of a curl-like, B mode, polarization pattern in the cosmic microwave background (CMB) is primordial gravitational waves. At second-order B…
Inference of the optical depth to reionization from low multipole temperature and polarisation Planck data
Roger de Belsunce, Steven Gratton, William Coulton +1
This paper explores methods for constructing low multipole temperature and polarisation likelihoods from maps of the cosmic microwave background anisotropies that have complex nois…
