Complementarity of Weak Lensing and Peculiar Velocity Measurements in Testing General Relativity
Yong-Seon Song, Gong-Bo Zhao, David Bacon +3
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…
Probing modifications of General Relativity using current cosmological observations
Gong-Bo Zhao, Tommaso Giannantonio, Levon Pogosian +5
We test General Relativity (GR) using current cosmological data: the cosmic microwave background (CMB) from WMAP5 (Komatsu et al. 2009), the integrated Sachs-Wolfe (ISW) effect fro…
How to optimally parametrize deviations from General Relativity in the evolution of cosmological perturbations
Levon Pogosian, Alessandra Silvestri, Kazuya Koyama +1
The next generation of weak lensing surveys will trace the growth of large scale perturbations through a sequence of epochs, offering an opportunity to test General Relativity (GR)…
