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…

Ricci-Cubic Holographic Dark Energy: Confronting Observations, Stability and the Cosmic Coincidence Problem

Aritra Sanyal, Prabir Rudra

In this work, we constrain the parameter space of the Ricci-Cubic Holographic Dark Energy (RCHDE) model using several observational datasets, including Hubble parameter measurement…
