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…

Decoding the Gravitational Geometry and Stellar Photometric Profiles of Galaxy NGC 7331

Aritra Sanyal Bikramarka S. Choudhury Farook Rahaman

Galaxy rotation curves provide a powerful probe of mass distributions in spiral galaxies. We present a general relativistic analysis of NGC 7331 using its observed rotation curve a…

Warm Inflation in gravity

Tuhina Ghorui, Prabir Rudra, Farook Rahaman +1

We investigate warm inflation in the framework of gravity within a Friedmann-Robertson-Walker spacetime. Unlike cold inflation, where the inflaton evolves in isolation, warm…

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…

Revisiting The Gravitational Mirroring In Presence of Compact Objects

Bikramarka S Choudhury, Aritra Sanyal, Md Khalid Hossain +1

We propose a novel concept of astrophysical mirroring in the schwarzschild framework, which emerges as a direct consequence of gravitational lensing effects occurring in the immedi…

The peculiar case of the Viaggiu holographic dark energy

Somnath Saha, Subhajit Saha, Nilanjana Mahata

We study the plausibility of a holographic dark energy (HDE) model using the form of horizon entropy proposed by Viaggiu in 2014. This form of entropy is a generalization of the us…
