A Friendly Phantom: Late-time AdS-to-dS transition and cosmological tensions
Özgür Akarsu, Leandros Perivolaropoulos, A. Emrah Yükselci +1
We present Ph-CDM, a phantom-scalar realization within General Relativity of the sign-switching cosmological-constant idea, CDM, in which a phantom scalar evo…
A quantitative analysis of the effect of box size in N-body simulations of the matter power spectrum
Maxim Eingorn, Ezgi Yilmaz, A. Emrah Yükselci +1
We study the effect of box size on the matter power spectrum obtained via cosmological N-body simulations. Within the framework of the cosmic screening approach, we show that the r…
Mass density vs. energy density at cosmological scales
Maxim Eingorn, Ezgi Yilmaz, A. Emrah Yükselci +1
In the presence of the gravitational field, the energy density of matter no longer coincides with its mass density. A discrepancy exists, of course, also between the associated pow…
Effect of the spatial curvature of the Universe on the form of the gravitational potential
Maxim Eingorn, A. Emrah Yukselci, Alexander Zhuk
Within the cosmic screening approach, we obtain the exact formulas for the velocity-independent gravitational potentials produced by matter in the form of discrete sources distribu…
