The Masses and Shapes of Dark Matter Halos from Galaxy-Galaxy Lensing in the CFHTLS
Laura C. Parker, Henk Hoekstra, Michael J. Hudson +2
We present the first galaxy-galaxy weak lensing results using early data from the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS). These results are based on ~22 sq. deg. of…
The Stability of the Point Spread Function of the Advanced Camera for Surveys on the Hubble Space Telescope and Implications for Weak Gravitational Lensing
Jason D. Rhodes, Richard Massey, Justin Albert +11
(abridged) We examine the spatial and temporal stability of the HST ACS Wide Field Camera (WFC) point spread function (PSF) using the two square degree COSMOS survey. We show that…
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…
Large scale systematic signals in weak lensing surveys
Chris Vale, Henk Hoekstra, Ludovic van Waerbeke +1
We use numerical simulations to model the effect of seeing and extinction modulations on weak lensing surveys. We find that systematic fluctuations in the shear amplitude and sourc…
Detection of dark matter Skewness in the VIRMOS-DESCART survey: Implications for Ω_0
Ue-Li Pen, Tongjie Zhang, Ludovic van Waerbeke +3
Weak gravitational lensing provides a direct statistical measure of the dark matter distribution. The variance is easiest to measure, which constrains the degenerate product σ_8Ω^0…
Prospects for weak lensing/cosmic shear with VLTs
Y. Mellier, L. van Waerbeke, E. Bertin +4
The present status of weak lensing analyses of clusters of galaxies and of cosmic shear surveys are presented and discussed. We focus on the impact of very large telescopes on pres…
