Unequal-Time Correlators for Cosmology
T. D. Kitching, A. F. Heavens
Measurements of the power spectrum from large-scale structure surveys have to date assumed an equal-time approximation, where the full cross-correlation power spectrum of the matte…
The Limits of Cosmic Shear
Thomas D. Kitching, Justin Alsing, Alan F. Heavens +3
In this paper we discuss the commonly-used limiting cases, or approximations, for two-point cosmic shear statistics. We discuss the most prominent assumptions in this statistic: th…
Discrepancies between CFHTLenS cosmic shear & Planck: new physics or systematic effects?
Thomas D. Kitching, Licia Verde, Alan F. Heavens +1
There is currently a discrepancy in the measured value of the amplitude of matter clustering, parameterised using , inferred from galaxy weak lensing, and cosmic microwave bac…
