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…
Charged spherically symmetric Taub-NUT black hole solutions in gravity
G. G. L. Nashed, Kazuharu Bamba
theory is a modification of Einstein general relativity which has many interesting results in cosmology and astrophysics. To derive black hole solution in this theory is dif…
Parametrizations of Dark Energy Models in the Background of General Non-canonical Scalar Field in -dimensional Fractal Universe
Ujjal Debnath, Kazuharu Bamba
We explore non-canonical scalar field model in the background of non-flat -dimensional fractal Universe with cosmological constant on the condition that the matter and scala…
Higher dimensional rotating black hole solutions in quadratic gravitational theory and the conserved quantities
G. G. L. Nashed, Kazuharu Bamba
We explore the quadratic form of the gravitational theory to derive rotating -dimensions black hole solutions with rotation parameters. Here, is…
