The Lambert function: A newcomer in the Cosmology class?

Subhajit Saha, Kazuharu Bamba

We propose a novel equation of state (EoS) which explains the evolutionary history of a flat Friedmann-Lemaitre-Robertson-Walker (FLRW) Universe. The uniqueness of this EoS lies in…

Charged Gravastars in Modified Gravity

Z. Yousaf, Kazuharu Bamba, M. Z. Bhatti +1

In this paper, we investigate the effects of electromagnetic field on the isotropic spherical gravastar models in metric gravity. For this purpose, we have explored singul…

Dissipative Self-Gravitating Systems in Modified Gravity

M. Z. Bhatti, Kazuharu Bamba, Z. Yousaf +1

We discuss the gravitational collapse of spherical compact objects in the background of theory, where represent the Ricci scalar, is the trace of energy momentum…

On Reconstruction of Extended Teleparallel Gravity from the Cosmological Jerk Parameter

Soumya Chakrabarti, Jackson Levi Said, Kazuharu Bamba

Teleparallel gravity offers a path to resolve a number of longstanding issues in general relativity by re-interpreting gravitation as an artifact of torsion rather than curvature.…

Charged (A)dS black hole solutions in conformal teleparallel equivalent of general relativity

G. G. L. Nashed, Kazuharu Bamba

We continue our study in 4-dimension to derive non-charged and charged (Anti)-de Sitter black hole solutions in conformal teleparallel equivalent of general relativity. The non-cha…

The possibility of a stable flat dark energy-dominated Swiss-cheese Brane-world universe with a deceleration-acceleration transition

Nasr Ahmed, Kazuharu Bamba, F. Salama

In this paper, we study the possibility of obtaining a stable flat dark energy-dominated universe in a good agreement with observations in the framework of Swiss-cheese Brane-world…
