Asymptotic Solutions of Radiating Stars
R. S. Bogadi, G. Leon, M. Govender +3
We investigate the evolution of the surface of radiating stars by studying the asymptotic behaviour of exact solutions initiated via the stationary boundary condition. This boundar…
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…
Hints Beyond CDM from Barrow and Tsallis Holographic Dark Energy with GO cutoff
G. G. Luciano, A. Paliathanasis, G. Leon +2
Barrow and Tsallis Holographic Dark Energy (HDE) are two recent extensions of the standard HDE framework, obtained by introducing generalized entropy corrections through the Barrow…
Anisotropic Spacetimes in -gravity: Bianchi I, Bianchi III and Kantowski-Sachs Cosmologies
R. Bogadi, A. Giacomini, M. Govender +3
We investigate the evolution of cosmological anisotropies within the framework of -gravity. Specifically, we consider a locally rotationally symmetric geometry in…
