Euclid Definition Study Report
R. Laureijs, J. Amiaux, S. Arduini +216
Euclid is a space-based survey mission from the European Space Agency designed to understand the origin of the Universe's accelerating expansion. It will use cosmological probes to…
Cosmological information in Gaussianised weak lensing signals
B. Joachimi, A. N. Taylor, A. Kiessling
We investigate the information on cosmology contained in Gaussianised weak gravitational lensing convergence fields. Employing Box-Cox transformations to determine optimal transfor…
Forecasts of non-Gaussian parameter spaces using Box-Cox transformations
B. Joachimi, A. N. Taylor
Forecasts of statistical constraints on model parameters using the Fisher matrix abound in many fields of astrophysics. The Fisher matrix formalism involves the assumption of Gauss…
Cosmic magnification: nulling the intrinsic clustering signal
Alan F. Heavens, Benjamin Joachimi
We investigate the extent to which the pure magnification effect of gravitational lensing can be extracted from galaxy clustering statistics, by a nulling method which aims to elim…
