Cosmographic analysis of a closed bouncing universe with the varying cosmological constant in gravity

Vinod Kumar Bhardwaj, Anirudh Pradhan, Nasr Ahmed +1

Modeling of matter bounce in gravity has been presented with no violation of the null energy condition. Only a closed universe with negative pressure is allowed in good ag…

Some cosmological features of 4D Gauss-Bonnet gravity with varying cosmological constant

Nasr Ahmed, Ajab A. Alfreedi, Alaa A. Alzulaibani

We explore some cosmological features of the newly suggested 4D Gauss-Bonnet gravity through two different models assuming a varying cosmological constant. Observational constraint…

A non-singular closed bouncing universe without violation of null energy condition

Nasr Ahmed, Tarek M. Kamel, Mohamed I Nouh

A matter bouncing entropy-corrected cosmological model has been suggested. The model allows only positive curvature with negative pressure and no violation of the null energy condi…
