PSF calibration requirements for dark energy from cosmic shear
S. Paulin-Henriksson, A. Amara, L. Voigt +2
The control of systematic effects when measuring galaxy shapes is one of the main challenges for cosmic shear analyses. In this context, we study the fundamental limitations on she…
Systematic Bias in Cosmic Shear: Beyond the Fisher Matrix
Adam Amara, Alexandre Refregier
We describe a method for computing the biases that systematic signals introduce in parameter estimation using a simple extension of the Fisher matrix formalism. This allows us to c…
COSMOS: 3D weak lensing and the growth of structure
Richard Massey, Jason Rhodes, Alexie Leauthaud +17
We present a three dimensional cosmic shear analysis of the Hubble Space Telescope COSMOS survey, the largest ever optical imaging program performed in space. We have measured the…
