Effects of anisotropic pressure on interacting quark star structure
Juan M. Z. Pretel, Takol Tangphati, Ayan Banerjee +1
Perturbative Quantum Chromodynamics (pQCD) corrections and color superconductivity predict that strongly interacting matter can reveal new physical phenomena under extreme conditio…
Exact Solution of Bardeen Black Hole in Einstein-Gauss-Bonnet gravity
Amit Kumar, Dharm Veer Singh, Yerlan Myrzakulov +2
We have obtained a new exact regular black hole solution for the EGB gravity coupled with nonlinear electrodynamics in AdS space. The numerical analysis of horizon structure sugges…
Geodesic structure of generalized Vaidya spacetime through the K-essence
Bivash Majumder, Maxim Khlopov, Saibal Ray +1
This article investigates on the radial and non-radial geodesic structures of the generalized K-essence Vaidya spacetime. Within the framework of K-essence geometry, it is importan…
A power law solution for FRLW Universe with observational constraints
Lokesh Kumar Sharma, Suresh Parekh, Sanjay Maurya +4
This paper examines a power law solution under gravity for an isotropic and homogeneous universe by considering its functional form as , where is a p…
Cosmological model with linear equation of state parameter in f(R, Lm) gravity
Romanshu Garg, G. P. Singh, Ashwini R Lalke +1
In this paper, we examine the universe's expansion in gravity for a particular form of . The field equations for flat FLRW metri…
(Anti-)BRST Symmetries in FLRW Model: Supervariable Approach
Aradhya Shukla, Dharm Veer Singh, R. Kumar
Friedmann-Lemaitre-Robertson-Walker (FLRW) model, representing the isotropic and homogeneous Universe, has an inherent diffeomorphism (or reparametrization) invariance. For a given…
