Spatial Propagation of Weak Lensing Shear Response Corrections

T. D. Kitching, N. Tessore, P. L. Taylor

In this paper we show how response function corrections to shear measurements (e.g. as required by Metacalibration) propagate into cosmic shear power spectra. We investigate a 2-sp…

The Impact of Quadratic Biases on Cosmic Shear

T. D. Kitching, A. C. Deshpande

In this paper we revisit potential biases in cosmic shear power spectra caused by bias terms that multiply up to quadratic powers of the shear. Expanding the multiplicative bias fi…

Mapping Spatially Varying Additive Biases in Cosmic Shear Data

T. D. Kitching, A. C. Deshpande, P. L. Taylor

In this paper we address the challenge of extracting maps of spatially varying unknown additive biases from cosmic shear data. This is done by exploiting the isotropy of the cosmic…

Cosmological Parameter Biases from Doppler-Shifted Weak Lensing in Stage IV Experiments

Anurag C. Deshpande, Thomas D. Kitching

The advent of Stage IV weak lensing surveys will open up a new era in precision cosmology. These experiments will offer more than an order-of-magnitude leap in precision over exist…

Accessing the high- frontier under the Reduced Shear Approximation with -cut Cosmic Shear

Anurag C. Deshpande, Peter L. Taylor, Thomas D. Kitching

The precision of Stage IV cosmic shear surveys will enable us to probe smaller physical scales than ever before, however, model uncertainties from baryonic physics and non-linear s…

Propagating residual biases in masked cosmic shear power spectra

T. D. Kitching, A. C. Deshpande, P. L. Taylor

In this paper we derive a full expression for the propagation of weak lensing shape measurement biases into cosmic shear power spectra including the effect of missing data. We show…
