Observational Constraints in Nonlocal Gravity: the Deser-Woodard Case
Luca Amendola, Yves Dirian, Henrik Nersisyan +1
We study the cosmology of a specific class of nonlocal model of modified gravity, the so-called Deser-Woodard (DW) model, modifying the Einstein-Hilbert action by a term $\sim R f(…
Growth of perturbations in nonlocal gravity with non-CDM background
Sohyun Park, Arman Shafieloo
We re-analyze the nonlocal gravity model of Deser and Woodard which was proposed to account for the current phase of cosmic acceleration. We show that the growth of perturbations p…
Non-local bispectra from super cosmic variance
Bekir Baytaş, Aruna Kesavan, Elliot Nelson +2
We present examples of non-Gaussian statistics that can induce bispectra matching local and non-local (including equilateral) templates in biased sub-volumes. We find cases where t…
Nonlocal Gravity and Structure in the Universe
Scott Dodelson, Sohyun Park
The observed acceleration of the Universe can be explained by modifying general relativity. One such attempt is the nonlocal model of Deser and Woodard. Here we fix the background…
Structure formation in a nonlocally modified gravity model
Sohyun Park, Scott Dodelson
We study a nonlocally modified gravity model proposed by Deser and Woodard which gives an explanation for current cosmic acceleration. By deriving and solving the equations governi…
