2010/11/11
A new cosmic shear analysis pipeline SUNGLASS (Simulated UNiverses for Gravitational Lensing Analysis and Shear Surveys) is introduced. SUNGLASS is a pipeline that rapidly generates simulated universe...
Complementarity of Weak Lensing and Peculiar Velocity Measurements in Testing General Relativity
Complementarity of Weak Lensing Peculiar Velocity Measurements General Relativity

2010/11/12
We explore the complementarity of weak lensing and galaxy peculiar velocity measurements to
better constrain modifications to General Relativity. We find no evidence for deviations from GR on cosmolo...
Combining cluster observables and stacked weak lensing to probe dark energy: Self-calibration of systematic uncertainties
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
