New constraints on parametrised modified gravity from correlations of the CMB with large scale structure
Tommaso Giannantonio, Matteo Martinelli, Alessandra Silvestri +1
We study the effects of modified theories of gravity on the cosmic microwave background (CMB) anisotropies power spectrum, and in particular on its large scales, where the integrat…
Constraining modified growth patterns with tomographic surveys
Alessandra Silvestri
Viable models of modified gravity designed to produce cosmic acceleration at the current epoch, closely mimic the CDM model at the level of background cosmology. However, this d…
Reconstructing the Peculiar Velocity of the Local Group with Modified Gravity and 2MASS
Aidan C Crook, Alessandra Silvestri, Phillip Zukin
The peculiar velocity of the Local Group, reconstructed from inhomogeneities in the local density field, differs in direction and magnitude from the velocity inferred from the Cosm…
Cosmological Tests of General Relativity with Future Tomographic Surveys
Gong-Bo Zhao, Levon Pogosian, Alessandra Silvestri +1
Future weak lensing surveys will map the evolution of matter perturbations and gravitational potentials, yielding a new test of general relativity on cosmic scales. They will probe…
Approaches to Understanding Cosmic Acceleration
Alessandra Silvestri, Mark Trodden
Theoretical approaches to explaining the observed acceleration of the universe are reviewed. We briefly discuss the evidence for cosmic acceleration, and the implications for stand…
