Noncoincidence -Cosmology with Dark Matter Coupled to Gravity
A. Abebe, P. S. Apostolopoulos, A. Giacomini +3
We investigate FLRW cosmology in the framework of symmetric teleparallel gravity with a nonminimal coupling between dark matter and the gravitational field. In the noncoinci…

Viscous cosmological fluids and large-scale structure
BG Mbewe, RR Mekuria, S Sahlu +1
In this paper, we study the viscous fluid cosmological model that when certain conditions are invoked mimics the CDM model. The background equations governing the evolution of…
