Dynamical Structure of Viscous Accretion Disks with Shocks
Santabrata Das, Peter A. Becker, Truong Le
We develop and discuss global accretion solutions for viscous ADAF disks containing centrifugally supported isothermal shock waves. The fact that such shocks can exist at all in AD…
A study of the Correlation of Arrival Directions of UHECRs with the Large Scale Structure of the Universe
Dongsu Ryu, Hyesung Kang, Santabrata Das
Ultrahigh energy cosmic rays (UHECRs) are believed to originate from astrophysical sources, which should trace the large scale structure (LSS) of the universe. On the other hand, t…
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…
