Measurement of Cosmic Shear with the Space Telescope Imaging Spectrograph
Jason Rhodes, Alexandre Refregier, Nicholas R. Collins +3
Weak lensing by large-scale structure allows a direct measure of the dark matter distribution. We have used parallel images taken with the Space Telescope Imaging Spectrograph (STI…
Weak Gravitational Lensing by Large-Scale Structure
Alexandre Refregier
Weak gravitational lensing provides a unique method to map directly the distribution of dark matter in the universe and to measure cosmological parameters. This cosmic-shear techni…
The XMM-LSS survey. Survey design and first results
M. Pierre, I. Valtchanov, B. Altieri +36
We have designed a medium deep large area X-ray survey with XMM - the XMM Large Scale Structure survey, XMM-LSS - with the scope of extending the cosmological tests attempted using…
Weak Lensing from Space III: Cosmological Parameters
Alexandre Refregier, Richard Massey, Jason Rhodes +6
Weak gravitational lensing provides a unique method to directly map the dark matter in the universe and measure cosmological parameters. Current weak lensing surveys are limited by…
Weak Lensing from Space II: Dark Matter Mapping
Richard Massey, Jason Rhodes, Alexandre Refregier +8
We study the accuracy with which weak lensing measurements could be made from a future space-based survey, predicting the subsequent precisions of 3-dimensional dark matter maps, p…
Image Simulation with Shapelets
Richard Massey, Alexandre Refregier, Christopher J. Conselice +1
We present a method to simulate deep sky images, including realistic galaxy morphologies and telescope characteristics. To achieve a wide diversity of simulated galaxy morphologies…
