Is the CDM Model in Crisis?
Himanshu Chaudhary, Salvatore Capozziello, Subhrat Praharaj +2
We present strong evidence for dynamical dark energy that challenges the standard CDM model. Several dark energy scenarios are explored, including CDM, logarithmic, expo…
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…
Bouncing cosmology in gravity
J. K. Singh, Kazuharu Bamba, Ritika Nagpal +1
A cosmological model with a specific form of the Hubble parameter is constructed in a flat homogeneous, and isotropic background in the framework of gravity, where is…
