Large-Angle Correlations in the Cosmic Microwave Background

George Efstathiou, Yin-Zhe Ma, Duncan Hanson

It has been argued recently by Copi etal (2009) that the lack of large angular correlations of the CMB temperature field provides strong evidence against the standard, statisticall…

Weak lensing of the CMB

Duncan Hanson, Anthony Challinor, Antony Lewis

The cosmic microwave background (CMB) represents a unique source for the study of gravitational lensing. It is extended across the entire sky, partially polarized, located at the e…

Estimators for CMB Statistical Anisotropy

Duncan Hanson, Antony Lewis

We use quadratic maximum-likelihood (QML) estimators to constrain models with Gaussian but statistically anisotropic Cosmic Microwave Background (CMB) fluctuations, using CMB maps…

Lensing reconstruction from PLANCK sky maps: inhomogeneous noise

Duncan Hanson, Graca Rocha, Krzysztof Gorski

We discuss the effects of inhomogeneous sky-coverage on CMB lens reconstruction, focusing on application to the recently launched Planck satellite. We discuss the mean-field which…

CMB lensing and primordial non-Gaussianity

Duncan Hanson, Kendrick M. Smith, Anthony Challinor +1

We study the effects of gravitational lensing on the estimation of non-Gaussianity from the bispectrum of the cosmic microwave background (CMB) temperature anisotropies. We find th…
