Dissipative accretion flows around a rotating black hole
Santabrata Das, Sandip K. Chakrabarti
We study the dynamical structure of a cooling dominated rotating accretion flow around a spinning black hole. We show that non-linear phenomena such as shock waves can be studied i…
Turbulence and Magnetic Fields in the Large Scale Structure of the Universe
Dongsu Ryu, Hyesung Kang, Jungyeon Cho +1
The nature and origin of turbulence and magnetic fields in the intergalactic space are important problems that are yet to be understood. We propose a scenario in which turbulent fl…
Computation of mass loss from viscous accretion disc in presence of cooling
Santabrata Das, Indranil Chattopadhyay
Rotating accretion flow may undergo centrifugal pressure mediated shock transition even in presence of various dissipative processes, such as viscosity and cooling mechanism. The e…
Propagation of UHE Protons through Magnetized Cosmic Web
Santabrata Das, Hyesung Kang, Dongsu Ryu +1
If ultra-high-energy cosmic rays (UHECRs) originate from extragalactic sources, understanding the propagation of charged particles through the magnetized large scale structure (LSS…
Parameter space study of magnetohydrodynamic flows around magnetized compact objects
Santabrata Das, Sandip K. Chakrabarti
We solve the magnetohydrodynamic (MHD) equations governing axisymmetric flows around neutron stars and black holes and found all possible solution topologies for adiabatic accretio…
Behaviour of dissipative accretion flows around black holes
Santabrata Das
We investigate the behaviour of dissipative accreting matter close to a black hole as it provides the important observational features of galactic and extra-galactic black holes ca…
