Do measurements of the one-point distribution of aperture-mass improve constraints on cosmology ?
Dipak Munshi, Patrick Valageas
We study the possibility of using the entire probability distribution function (PDF) of the aperture mass Map and its related cumulative probability distribution function (CPDF) to…
Principal Component Analysis of Weak Lensing Surveys
Dipak Munshi, Martin Kilbinger
We study degeneracies between cosmological parameters and measurement errors from cosmic shear surveys using a principal component analysis of the Fisher matrix. We simulate realis…
Cosmological Constraints from Weak Lensing Surveys
Dipak Munshi, Patrick Valageas
Focusing on the well motivated aperture mass statistics $\Map$, we study the possibility of constraining cosmological parameters using future space based SNAP class weak lensing mi…
Cosmology with Weak Lensing Surveys
Dipak Munshi, Patrick Valageas
Weak gravitational lensing surveys measure the distortion of the image of distant sources due to the deflections of light rays by the fluctuations of the gravitational potential al…
