Integrability conditions of quasi-Newtonian cosmologies in modified gravity
Amare Abebe, Peter K. S. Dunsby, Deon Solomons
We investigate the integrability conditions of a class of shear-free perfect-fluid cosmological models within the framework of anisotropic fluid sources, applying our results to f(…

Chaplygin-gas Solutions of f(R) Gravity
Maye Elmardi, Amare Abebe, Abiy Tekola
We explore exact f(R) gravity solutions that mimic Chaplygin-gas inspired LCDM cosmology. Starting with the original and modified Chaplygin gas equations of state, we reconstruct t…
