Black hole quasinormal modes and isospectrality in Deser-Woodard nonlocal gravity
Che-Yu Chen, Sohyun Park
We investigate the gravitational perturbations of the Schwarzschild black hole in the nonlocal gravity model recently proposed by Deser and Woodard (DW-II). The analysis is perform…
Primordial bouncing cosmology in the Deser-Woodard nonlocal gravity
Che-Yu Chen, Pisin Chen, Sohyun Park
The Deser-Woodard (DW) nonlocal gravity model has been proposed in order to describe the late-time acceleration of the universe without introducing dark energy. In this paper we fo…
Does nonlocal gravity yield divergent gravitational energy-momentum fluxes?
Yi-Zen Chu, Sohyun Park
Energy-momentum conservation requires the associated gravitational fluxes on an asymptotically flat spacetime to scale as , as , where is the distance betw…
Do the Spirits Rise?
Sohyun Park, R. P. Woodard
A nonlocal gravity model based on achieves the phenomenological goals of generating cosmic acceleration without dark energy and of suppressing the growth of per…
Revival of the Deser-Woodard nonlocal gravity model: Comparison of the original nonlocal form and a localized formulation
Sohyun Park
We examine the origin of two opposite results for the growth of perturbations in the Deser-Woodard (DW) nonlocal gravity model. One group previously analyzed the model in its origi…
One loop corrected conformally coupled scalar mode equations during inflation
Sibel Boran, Emre Onur Kahya, Sohyun Park
We employ a fully renormalized computation of the one loop contribution to the self-mass-squared of the conformally coupled (CC) scalar interacting with gravitons during inflation…
