DUNE: The Dark Universe Explorer
A. Refregier, O. Boulade, Y. Mellier +22
Understanding the nature of Dark Matter and Dark Energy is one of the most pressing issues in cosmology and fundamental physics. The purpose of the DUNE (Dark UNiverse Explorer) mi…
Optimal Surveys for Weak Lensing Tomography
Adam Amara, Alexandre Refregier
Weak lensing surveys provide a powerful probe of dark energy through the measurement of the mass distribution of the local Universe. A number of ground-based and space-based survey…
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 XMM Large Scale Structure survey: The X-ray pipeline and survey selection function
F. Pacaud, M. Pierre, A. Refregier +11
We present the X-ray pipeline developed for the purpose of the cluster search in the XMM-LSS survey. It is based on a two-stage procedure via a dedicated handling of the Poisson na…
