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…
