An Abel-Inversion Formalism for Spacetime Metric Reconstruction from Light Deflection
Aniruddha Ghosh, Ujjal Debnath
We develop an inverse lensing formalism for reconstructing the metric function of a static, spherically symmetric spacetime directly from the gravitational deflection angle of ligh…
Charged Black Hole Solution in Hoyle Narlikar Gravity and its Thermodynamic Properties
Aniruddha Ghosh, Ujjal Debnath
In this paper, we derive a new class of analytic black hole solutions within the framework of Hoyle--Narlikar gravity, where the black hole is surrounded by an electric charge acti…
Thermodynamic stability of the new black hole solution in gravity
Aniruddha Ghosh, Ujjal Debnath
In this literature, we derive an approximate black hole metric within the \( f(R, G, T) \) gravity framework, where the black hole is surrounded by an anisotropic fluid as the matt…
Exploring the Observational Constraints and Cosmological Dynamics in f(Q,L_m) Gravity
Ratul Mandal, Anamika Kotal, Vipin Kumar Sharma +1
We explore two scenarios of gravity: linear and non-linear gravity models. The dynamical system analysis identifies two critical points for each of the propose…
Influence of Generalized Ghost Dark Energy on Wormhole Geometry
Soubhik Paramanik, Anamika Kotal, Ujjal Debnath
This article presents a wormhole solution constructed from a generalized ghost dark energy (GGDE) source in general relativity. At first, a brief review of GGDE is presented along…
CDM Model: Cosmological Implications and Dynamical System Analysis
Himanshu Chaudhary, Ratul Mandal, Masroor Bashir +2
We investigated a time-varying cosmological constant model using recent BAO measurements from DESI DR2, combined with Type Ia supernova samples (Pantheon, DES-Dovekie, and Un…
