Outflow Behavior from the Transonic Advective Disks: A Hydrodynamical Simulation Study
Sanjit Debnath, Indranil Chattopadhyay, Raj Kishor Joshi +3
We investigate the properties of outflows from the transonic advective accretion disk using hydrodynamical numerical simulations. We consider two different disk temperatures with a…
Effect of Multi-Species Plasma on Fanaroff-Riley Radio Jets
Priyesh Kumar Tripathi, Indranil Chattopadhyay, Raj Kishor Joshi +3
The Fanaroff-Riley (FR) dichotomy observed in extragalactic radio jets has been attributed to a range of possible mechanisms, including intrinsic jet properties such as the presenc…
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…
Bridging X-ray Polarization with Timing & Spectroscopic Parameters of a galactic black hole: Swift J1727.8-1613
Arka Chatterjee, Sujoy K. Nath, Kaushik Chatterjee +5
We report the discovery of a correlated energy-dependent time lag and degree of polarization for Swift J1727.8-1613 during its 2023 outburst. The energy-dependent time lag is measu…
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…
Magnetohydrodynamic Simulations of Transonic Accretion Flows
Raj Kishor Joshi, Antonios Tsokaros, Sanjit Debnath +2
Theoretical studies of transonic accretion onto black holes reveal a wide range of possible solutions, broadly classified into smooth flows and flows featuring shocks. Accretion so…
Astrophysics with Compact Objects: An Indian Perspective, Present Status and Future Vision
Manjari Bagchi, Prasanta Bera, Aru Beri +18
Astrophysical compact objects, viz., white dwarfs, neutron stars, and black holes, are the remnants of stellar deaths at the end of their life cycles. They are ideal testbeds for v…
