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…

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…

Radiative acceleration of relativistic jets from accretion discs around black holes

Indranil Chattopadhyay, Raj Kishor Joshi, Sanjit Debnath +2

Matter falling onto black holes, {also called} accretion discs, emit intense high-energy radiation. Accretion discs during {hard to hard intermediate} spectral states also emit bip…

Numerical Simulation of Radiatively driven Transonic Relativistic Jets

Raj Kishor Joshi, Indranil Chattopadhyay, Antonios Tsokaros +1

We perform the numerical simulations of axisymmetric, relativistic, optically thin jets under the influence of the radiation field of an accretion disk. We show that starting from…

Oscillating shocks in the transonic, viscous, variable , accretion flows around black holes

Sanjit Debnath, Indranil Chattopadhyay, Raj Kishor Joshi

We investigate the time evolution of the transonic-viscous accretion flow around a non-rotating black hole. The input parameters used for the simulation are obtained from semi-anal…

Two-temperature accretion flows around strongly magnetized stars and their spectral analysis

Shilpa Sarkar, Kuldeep Singh, Indranil Chattopadhyay +1

We investigate two-temperature accretion flows onto strongly magnetized compact stars. Matter is accreted in the form of an accretion disc upto the disc radius (), where…
