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…
Spherically symmetric gravitational collapse in the background of Chaplygin gas
Anjali Pandey, Rajesh Kumar, Sudhir Kumar Srivastava
This paper considers the spherically symmetric gravitational collapse in the background of Chaplygin gas as dark energy component. The dark energy is assumed to be generalized and…
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…
Theoretical and Experimental Constraints for the Equation of State of Dense and Hot Matter
Rajesh Kumar, Veronica Dexheimer, Johannes Jahan +57
This review aims at providing an extensive discussion of modern constraints relevant for dense and hot strongly interacting matter. It includes theoretical first-principle results…
