Dynamical dark energy with AdS-dS transitions vs. Baryon Acoustic Oscillations at 2.3-2.4
Ãzgür Akarsu, Maxim Eingorn, Leandros Perivolaropoulos +2
In this paper, written in memory of Alexei Starobinsky, we discuss the observational viability of the Ph-CDM model - a dynamical dark energy scenario based on a phantom…
Suppression of matter density growth at scales exceeding the cosmic screening length
Maxim Eingorn, Ezgi Yilmaz, A. Emrah Yükselci +1
One of the main objectives of modern cosmology is to explain the origin and evolution of cosmic structures at different scales. The principal force responsible for the formation of…
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…
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…
