Delensing CMB Polarization with External Datasets
Kendrick M. Smith, Duncan Hanson, Marilena LoVerde +2
One of the primary scientific targets of current and future CMB polarization experiments is the search for a stochastic background of gravity waves in the early universe. As instru…
CMB temperature lensing power reconstruction
Duncan Hanson, Anthony Challinor, George Efstathiou +1
We study reconstruction of the lensing potential power spectrum from CMB temperature data, with an eye to the Planck experiment. We work with the optimal quadratic estimator of Oka…
The Herschel-SPIRE Legacy Survey (HSLS): the scientific goals of a shallow and wide submillimeter imaging survey with SPIRE
Asantha Cooray, Steve Eales, Scott Chapman +247
A large sub-mm survey with Herschel will enable many exciting science opportunities, especially in an era of wide-field optical and radio surveys and high resolution cosmic microwa…
Asymmetric Beams and CMB Statistical Anisotropy
Duncan Hanson, Antony Lewis, Anthony Challinor
Beam asymmetries result in statistically-anisotropic cosmic microwave background (CMB) maps. Typically, they are studied for their effects on the CMB power spectrum, however they m…
