Screening vs. gevolution: in chase of a perfect cosmological simulation code

  title={Screening vs. gevolution: in chase of a perfect cosmological simulation code},
  author={M. Eingorn and A. Yukselci and A. Zhuk},
We compare two competing relativistic approaches to the N-body simulation of the Universe large-scale structure. To this end, employing the corresponding alternative computer codes (“gevolution” and “screening”), we conduct a series of cosmological simulations in boxes of different sizes and calculate the power spectra of the scalar perturbation Φ, the frame-dragging vector potential B and the difference between scalar modes χ = Φ−Ψ. We demonstrate that the corresponding power spectra are in… Expand

gevolution: a cosmological N-body code based on General Relativity
We present a new N-body code, gevolution, for the evolution of large scale structure in the Universe. Our code is based on a weak field expansion of General Relativity and calculates all six metricExpand
Duel of cosmological screening lengths
Two distinct perturbative approaches have been recently formulated within General Relativity, arguing for the screening of gravity in the $\Lambda$CDM Universe. In this paper we compare them and showExpand
