A Nonsingular Logarithmic Bouncing Cosmology in Gravity with Thermodynamic Viability
Anjani, Pankaj Kumar, S. H. Shekh +1
We present a nonsingular bouncing cosmological model in the framework of modified gravity within a spatially flat Friedmann--Robertson--Walker universe. A logarithmic time…

Interacting Ghost Dark Energy with Sign-Changeable Coupling in Brans-Dicke Cosmology
Kirti Mehta, Pankaj Kumar, N. Myrzakulov +1
In this study, we analyze the ghost dark energy model in Brans-Dicke cosmology in the framework of a flat Friedmann-Lemaitre-Robertson-Walker universe. We consider an interaction b…
