Non-local gravity and comparison with observational datasets

Yves Dirian, Stefano Foffa, Martin Kunz +2

We study the cosmological predictions of two recently proposed non-local modifications of General Relativity. Both models have the same number of parameters as $Λ$ CDM, with a mass…

Stability analysis and future singularity of the $m^{2} R □^{- 2} R$ model of non-local gravity

Yves Dirian, Ermis Mitsou

We analyse the classical stability of the model proposed by Maggiore and Mancarella, where gravity is modified by a term $\sim m^{2} R □^{- 2} R$ to produce the late-time accelerat…

Cosmological perturbations and structure formation in nonlocal infrared modifications of general relativity

Yves Dirian, Stefano Foffa, Nima Khosravi +2

We study the cosmological consequences of a recently proposed nonlocal modification of general relativity, obtained by adding a term $m^{2} R □^{- 2} R$ to the Einstein-Hilbert acti…
