Bremsstrahlung photons from stopping in heavy-ion collisions
Sohyun Park, Urs Achim Wiedemann
We examine the spectrum of bremsstrahlung photons that results from the stopping of the initial net charge distributions in ultrarelativistic nucleus-nucleus collisions at the CERN…
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…
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(…
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…
