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…
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…
Euclid: The reduced shear approximation and magnification bias for Stage IV cosmic shear experiments
A. C. Deshpande, T. D. Kitching, V. F. Cardone +69
Stage IV weak lensing experiments will offer more than an order of magnitude leap in precision. We must therefore ensure that our analyses remain accurate in this new era. Accordin…
