Outflow Behavior from the Transonic Advective Disks: A Hydrodynamical Simulation Study

Sanjit Debnath, Sanjit Denath, Indranil Chattopadhyay +4

The study uses hydrodynamical simulations to examine how viscosity and radiative cooling affect outflows from hot and cold transonic advective accretion disks, finding that higher…

Effect of Multi-Species Plasma on Fanaroff-Riley Radio Jets

Priyesh Kumar Tripathi, Priyesh K. Tripathi, Indranil Chattopadhyay +5

The paper uses 3D magnetohydrodynamic simulations to study how different plasma compositions affect the stability and morphology of low‑power Fanaroff‑Riley I radio jets.

QPOs from the Viscous Transonic Accretion Flow Around a Spinning Black Hole

Sanjit Debnath, Indranil Chattopadhyay, Soumyadip Mandal +3

We investigate the dynamics of transonic advective accretion flows around spinning black holes in the presence of viscosity. The spacetime of a Kerr black hole is approximated usin…

How Plasma Properties of the Fanaroff-Riley Jet can Shape its Morphology

Priyesh Kumar Tripathi, Indranil Chattopadhyay, Raj Kishor Joshi +3

Extragalactic jets are broadly classified into two categories based on radio observations: core-brightened jets, known as Fanaroff-Riley Type I (FR I), and edge-brightened jets, cl…

Dynamical properties of oscillating, viscous, transonic accretion disks around black holes

Sanjit Debnath, Indranil Chattopadhyay, Raj Kishor Joshi +3

We investigate the time evolution of sub-Keplerian transonic accretion flow onto a non-rotating black hole using axisymmetric viscous hydrodynamic simulations. We simulate the accr…
