Black Hole Solutions with Constant Ricci Scalar in a Model of Finsler Gravity
Z. Nekouee, S. K. Narasimhamurthy, S. K. J. Pacif
Ricci scalar being zero is equivalent to the vacuum field equation in Finsler space-time. The Schwarzschild metric can be concluded from the field equation's solution if the space-…
Black hole formation in gravitational collapse and their astrophysical implications
Annu Jaiswal, Rajesh Kumar, Sudhir Kumar Srivastava +2
In this work, we have investigated a novel aspect of black hole (BH) formation during the collapse of a self-gravitating configuration. The exact solution of the Einstein field equ…
Diagnostic and Comparative Analysis of Dark Energy Models with Parametrizations
Dhruv Arora, Himanshu Chaudhary, Shibesh Kumar Jas Pacif +1
This manuscript presents a diagnostic analysis of three dark energy models resulting from the parametrization of the deceleration parameter. These models exhibit intriguing feature…
Astrophysical implications of an eternal homogeneous gravitational collapse model with a parametrization of expansion scalar
Annu Jaiswal, Rajesh Kumar, Sudhir Kumar Srivastava +1
In this study, we continue our previous work (Annu et al., 2023) by introducing a novel parametrization of the expansion scalar as a rational function of cosmic time . The p…
Eternal homogeneous gravitational collapse: A comprehensive analysis from parametrization
Annu Jaiswal, Rajesh Kumar, Sudhir Kumar Srivastava +1
A new class of self-gravitating collapsing star models with perfect fluid distributions is discussed in this work. The paper has a comprehensive analysis of a homogeneous gravitati…
