Reconstruction of Gravity from Geodesic Congruence Dynamics: Raychaudhuri Equation
Tuhina Ghorui, Prabir Rudra, Farook Rahaman
In this study, we use the Raychaudhuri equation as the essential geometrical tool to reconstruct the functional form of gravity within the context of symmetric teleparallel…
The New Dark Matter Density Profile from JWST JADES Galaxies
Aritra Sanyal, Farook Rahaman
We present the first dark matter density profile derived directly from James Webb Space Telescope JADES Data Release~3 NIRSpec observations of galaxies spanning the cosmi…
Observational Constraints and Cosmic Growth Index of Realistic Gravity Frameworks using MCMC Analysis
Praveen Kumar Dhankar, Munyeshyaka Albert, Mohit Thakre +3
We present a comprehensive observational analysis of modified Gauss--Bonnet, or , gravity by investigating both the background cosmological expansion and sub-horizon linear m…
A Dynamical-Photometric Phase Space for Spiral Galaxies: Probing the Local Coupling Between Light and Gravity
Aritra Sanyal, Farook Rahaman
The interplay between luminous matter distribution and the local gravitational field within disc galaxies encodes physical information beyond that captured by global scaling relati…
On the reconstruction of the Rotation Curve for Milky Way and its spacetime implications: a Machine Learning approach
Aritra Sanyal, Swapan Das, Farook Rahaman +1
We propose a machine learning-assisted analytical reconstruction of the Milky Way rotation curve and discuss its implications in a relativistic spacetime context. The rotation curv…
Exact Gravastar Solution
Farook Rahaman, Bikramarka S. Choudhury, Aritra Sanyal +2
Astrophysical black holes arise as exact solutions of the Einstein field equations. Therefore, any alternative, such as a gravastar, must satisfy the same level of mathematical rig…
