Magnetohydrodynamic Simulation Code CANS+: Assessments and Applications
Yosuke Matsumoto, Yuta Asahina, Yuki Kudoh +7
We present a new magnetohydrodynamic (MHD) simulation code with the aim of providing accurate numerical solutions to astrophysical phenomena where discontinuities, shock waves, and…
A radiation-hydrodynamic model of accretion columns for ultra-luminous X-ray pulsars
Tomohisa Kawashima, Shin Mineshige, Ken Ohsuga +1
Prompted by the recent discovery of pulsed emission from an ultra-luminous X-ray source, M82 X-2 ("ULX-pulsar"), we perform a two-dimensional radiation-hydrodynamic simulation of a…
TARGET 5: a new multi-channel digitizer with triggering capabilities for gamma-ray atmospheric Cherenkov telescopes
A. Albert, S. Funk, T. Kawashima +9
TARGET~5 is a new application-specific integrated circuit (ASIC) of the TARGET family, designed for the readout of signals from photosensors in the cameras of imaging atmospheric C…
Formation of Overheated Regions and Truncated Disks around Black Holes; Three-dimensional General Relativistic Radiation-magnetohydrodynamics Simulations
Hiroyuki R. Takahashi, Ken Ohsuga, Tomohisa Kawashima +1
Using three-dimensional general relativistic radiation magnetohydrodynamics simulations of accretion flows around stellar mass black holes, we report that the relatively cold disk…
