LeMoMaF: Lensed Mock Map Facility
Jaime E. Forero-Romero, Jeremy Blaizot, Julien Devriendt +2
We present the Lensed Mock Map Facility (LeMoMaF), a tool designed to perform mock weak lensing measurements on numerically simulated chunks of the universe. Coupling N-body simula…
The Shear TEsting Programme 2: Factors affecting high precision weak lensing analyses
Richard Massey, Catherine Heymans, Joel Berge +28
The Shear TEsting Programme (STEP) is a collaborative project to improve the accuracy and reliability of weak lensing measurement, in preparation for the next generation of wide-fi…
Cosmic variance of weak lensing surveys in the non-Gaussian regime
Elisabetta Semboloni, Ludovic van Waerbeke, Catherine Heymans +4
The results from weak gravitational lensing analyses are subject to a cosmic variance error term that has previously been estimated assuming Gaussian statistics. In this letter we…
Potential sources of contamination to weak lensing measurements: constraints from N-body simulations
Catherine Heymans, Martin White, Alan Heavens +2
We investigate the expected correlation between the weak gravitational shear of distant galaxies and the orientation of foreground galaxies, through the use of numerical simulation…
Tracking quintessence by cosmic shear - Constraints from VIRMOS-Descart and CFHTLS and future prospects
Carlo Schimd, Ismael Tereno, Jean-Philippe Uzan +6
Dark energy can be investigated in two complementary ways, by considering either general parameterizations or physically well-defined models. Following the second route, we explore…
Redshift and Shear Calibration: Impact on Cosmic Shear Studies and Survey Design
Ludovic Van Waerbeke, Martin White, Henk Hoekstra +1
The cosmological interpretation of weak lensing by large-scale structures requires knowledge of the redshift distribution of the source galaxies. Current lensing surveys are often…
