Weak-field limit of Kaluza-Klein model with non-linear perfect fluid
Ezgi Yalçınkaya, Alexander Zhuk
The main purpose of our paper is to construct a viable Kaluza-Klein model satisfying the observable constraints. To this end, we investigate the six-dimensional model with spherica…
Weak field limit of higher dimensional massive Brans-Dicke gravity: Observational constraints
Ozgur Akarsu, Alexey Chopovsky, Valerii Shulga +2
We consider higher-dimensional massive Brans-Dicke theory with Ricci-flat internal space. The background model is perturbed by a massive gravitating source which is pressureless in…
Analytic expressions for the second-order scalar perturbations in the CDM Universe within the cosmic screening approach
Maxim Eingorn, N. Duygu Guran, Alexander Zhuk
We study the second-order scalar perturbations in the conventional CDM Universe within the cosmic screening approach. The analytic expressions for both the velocity-independent…
