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…
Beyond the Mean-flow: A Spectral-Dynamic Approach to Unraveling the Physics of Droplet Capture in Fog Harvesting Meshes
Pradyumna Das, Ranjan Ganguly, Ashoke De
Fog harvesting efficiency with mesh collectors is governed by complex interactions between droplet inertia and geometry-induced flow structures. Although previous studies have prim…
Intrinsic coupling between transverse spherocity and elliptic flow in heavy-ion collisions
Subikash Choudhury, Ekata Nandy
Transverse spherocity () is an event-shape observable widely used to classify collision events according to their topology, particularly to distinguish jet-like from isotrop…
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…
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…
