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…

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…

Euclid: Forecasts for -cut Point Statistics

P. L. Taylor, T. Kitching, V. F. Cardone +92

Modelling uncertainties at small scales, i.e. high in the power spectrum , due to baryonic feedback, nonlinear structure growth and the fact that galaxies are biased trac…

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…

Post-Limber Weak Lensing Bispectrum, Reduced Shear Correction, and Magnification Bias Correction

Anurag C. Deshpande, Thomas D. Kitching

The significant increase in precision that will be achieved by Stage IV cosmic shear surveys means that several currently used theoretical approximations may cease to be valid. An…
