Masking Black Hole Spin with a Modified Chaplygin Gas Envelope: Radiative Degeneracies from a Phenomenological Three-Region Spacetime
Sandip Dutta
Theoretical interpretations of horizon-scale observations often rely on the idealized assumption of an isolated vacuum Kerr geometry. However, astrophysical black holes are expecte…
Filling the Shadow: A Propositional Model of Gravastar Accretion in Gravity
Sandip Dutta
While General Relativity remains our most rigorously tested framework for gravitation, the theoretical persistence of singularities within standard black hole solutions continues t…
Viscous Accretion Disks around Regular Black Holes Embedded in a Quintessence Dark Energy Field: Beyond the Novikov--Thorne Approximation
Sandip Dutta
We develop a comprehensive relativistic framework for geometrically thin, optically thick Shakura--Sunyaev -viscous accretion disks around rotating Hayward regular black holes e…
Breaking the Degeneracy: Spectral Hardening of Accretion Disks around Rotating Hayward Black Holes in Dark Matter Halos
Sandip Dutta
We investigate the thermodynamic and observable signatures of thin accretion disks surrounding rotating, regular Hayward black holes embedded within a macroscopic dark matter (DM)…
Viscous Dark Energy Accretion Activities : Sonic Speed, Angular Momentum and Mach Number Studies
Sandip Dutta, Promila Biswas, Ritabrata Biswas
In this present article, we study different accretion properties regarding viscous accretion of dark energy. Modified Chaplygin gas is chosen as the dark energy candidate. Viscosit…
Effect of Franchised Business models on Fast Food Company Stock Prices in Recession and Recovery with Weibull Analysis
Sandip Dutta, Vignesh Prabhu
At the initial stages of this research, the assumption was that the franchised businesses perhaps should not be affected much by recession as there are multiple cash pools availabl…
