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…
CMB Lensing Constraints on Dark Energy and Modified Gravity Scenarios
Erminia Calabrese, Asantha Cooray, Matteo Martinelli +4
Weak gravitational lensing leaves a characteristic imprint on the cosmic microwave background temperature and polarization angular power spectra. Here we investigate the possible c…
Cosmological constraints on the Hu-Sawicki modified gravity scenario
Matteo Martinelli, Alessandro Melchiorri, Luca Amendola
In this paper we place new constraints on a f(R) modified gravity model recently proposed by Hu and Sawicki. After checking that the Hu and Sawicki model produces a viable cosmolog…
