Handbook for the GREAT08 Challenge: An image analysis competition for cosmological lensing
Sarah Bridle, John Shawe-Taylor, Adam Amara +35
The GRavitational lEnsing Accuracy Testing 2008 (GREAT08) Challenge focuses on a problem that is of crucial importance for future observations in cosmology. The shapes of distant g…
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…
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…
Weak gravitational shear and flexion with polar shapelets
Richard Massey, Barnaby Rowe, Alexandre Refregier +2
We derive expressions, in terms of "polar shapelets", for the image distortion operations associated with weak gravitational lensing. Shear causes galaxy shapes to become elongated…
The Shear TEsting Programme 1: Weak lensing analysis of simulated ground-based observations
Catherine Heymans, Ludovic Van Waerbeke, David Bacon +22
The Shear TEsting Programme, STEP, is a collaborative project to improve the accuracy and reliability of all weak lensing measurements in preparation for the next generation of wid…
Dark energy and the evolution of spherical overdensities
Cathy Horellou, Joel Berge
We use the non-linear spherical model in cold dark matter (CDM) cosmologies with dark energy to investigate the effects of dark energy on the growth of structure and the formation…
