Effects of Fluid Composition on Spherical Flows around Black Holes
Indranil Chattopadhyay, Dongsu Ryu
Steady, spherically symmetric, adiabatic accretion and wind flows around non-rotating black holes were studied for fully ionized, multi-component fluids, which are described by a r…
Growth of Magnetic Fields Induced by Turbulent Motions
J. Cho, E. Vishniac, A. Beresnyak +2
We present numerical simulations of driven magnetohydrodynamic (MHD) turbulence with weak/moderate imposed magnetic fields. The main goal is to clarify dynamics of magnetic field g…
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…
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…
Propagation of UHE protons through a magnetized large scale structure
Hyesung Kang, Santabrata Das, Dongsu Ryu +1
The propagation of UHECRs is affected by the intergalactic magnetic fields that were produced during the course of the large scale structure formation of the universe. We adopt a n…
The X-ray Pulse Profile of BG CMi
Chul-Sung Choi, Tadayasu Dotani, Yonggi Kim +1
We present an analysis of the X-ray data of a magnetic cataclysmic variable, BG CMi, obtained with ROSAT in March 1992 and with ASCA in April 1996. We show that four peaks clearly…
