Transonic accretion and the analogue gravity in multi-component elliptical galaxies hosting pseudo-Schwarzschild black holes

Ripon Sk, Sangita Chatterjee, Sankhasubhra Nag

Low-angular-momentum, axisymmetric, inviscid accretion flows onto a black hole have been studied using the vertical equilibrium disc model, considering multiple pseudo-Schwarzschil…

Dynamic magnetic response in ABA type trilayered systems and compensation phenomenon

Enakshi Guru, Sonali Saha, Sankhasubhra Nag

Dynamic magnetic response in a trilayered structure with non-equivalent layers (ABA type) has been studied with Monte Carlo simulation using Metropolis algorithm. In each layer, fe…

Second Order Perturbative Effects on the Acoustic Geometry

Nandan Roy, Shivani Singh, Sankhasubhra Nag +1

In this work, we have studied the effect of higher order perturbations, particularly the second order in details, on the sonic horizon. We have considered two different schemes of…

Axially Symmetric Accretion of Fractal Medium onto Rotating Black Holes and the emergence of the Acoustic Manifold

Supriyo Majumder, Tapas K. Das, Sankhasubhra Nag

For three different geometric configurations of matter and two different thermodynamic equations of state, low angular momentum, multi-transonic, axially symmetric accretion flow o…
