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…
Binary black holes in magnetized AGN disks
Raj Kishor Joshi, Aryan Bhake, Biswajit Banerjee +7
Stellar-mass binary black hole (BBH) mergers occurring within the disks of active galactic nuclei (AGN) are promising sources for gravitational waves detectable by the LIGO, Virgo,…
On Disk Formation around Isolated Black Holes via Stream Accretion
Priyesh Kumar Tripathi, Indranil Chattopadhyay, Raj Kishor Joshi
We investigate accretion onto an isolated black hole from uniform winds. If the winds are directed towards the black hole, then the accretion process can be well described by the c…
