Screening in a new modified gravity model
Ozgur Akarsu, John D. Barrow, Charles V. R. Board +2
We study a new model of Energy-Momentum Squared Gravity (EMSG), called Energy-Momentum Log Gravity (EMLG), constructed by the addition of the term $f(T_{μν}T^{μν})=α\ln(λ\,T_{μν}T^…
Scalar perturbations in cosmological models: the cosmic screening approach
Ozgur Akarsu, Ruslan Brilenkov, Maxim Eingorn +2
We investigate cosmological perturbations for nonlinear models within the cosmic screening approach. Matter is considered both in the form of a set of discrete point-like ma…
Are dark energy models with variable EoS parameter compatible with the late inhomogeneous Universe?
Ozgur Akarsu, Mariam Bouhmadi-López, Maxim Brilenkov +3
We study the late-time evolution of the Universe where dark energy (DE) is presented by a barotropic fluid on top of cold dark matter (CDM). We also take into account the radiation…
