A Constraint On the Integrated Mass Power Spectrum out to z = 1100 from Lensing of the Cosmic Microwave Background
Joseph Smidt, Asantha Cooray, Alexandre Amblard +4
The temperature fluctuations and polarization of the Cosmic Microwave Background (CMB) are now a well-known probe of the Universe at an infant age of 400,000 years. During the tran…
New Approaches to Probing Minkowski Functionals
Dipak Munshi, Joseph Smidt, Asantha Cooray +3
We generalize the concept of the ordinary skew-spectrum to probe the effect of non-Gaussianity on the morphology of Cosmic Microwave Background (CMB) maps in several domains: in re…
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…
CMB Constraints on Primordial non-Gaussianity from the Bispectrum (f_{NL}) and Trispectrum (g_{NL} and τ_{NL}) and a New Consistency Test of Single-Field Inflation
Joseph Smidt, Alexandre Amblard, Christian T. Byrnes +3
We outline the expected constraints on non-Gaussianity from the cosmic microwave background (CMB) with current and future experiments, focusing on both the third (f_{NL}) and fourt…
Higher-order Statistics of Weak Lensing Shear and Flexion
Dipak Munshi, Joseph Smidt, Alan Heavens +2
Owing to their more extensive sky coverage and tighter control on systematic errors, future deep weak lensing surveys should provide a better statistical picture of the dark matter…
Primordial Non-Gaussianity from a Joint Analysis of Cosmic Microwave Background Temperature and Polarization
Dipak Munshi, Peter Coles, Asantha Cooray +2
We explore a systematic approach to the analysis of primordial non-Gaussianity using fluctuations in temperature and polarization of the Cosmic Microwave Background (CMB). Followin…
