Simulations of two-temperature jets in galaxy clusters: I. Effect of jet magnetization on dynamics and electron heating
Takumi Ohmura, Mami Machida
Non-radiating protons in the radio lobes have an essential role to form the jet morphology which is shown by recent radio and X-ray observations. However, since protons and electro…
Simulations of two-temperature jets in galaxy clusters: II. X-ray property of forward shock
Takumi Ohmura, Mami Machida, Hiroki Akamatsu
Forward shocks by radio jets, driven into the intracluster medium, are one of the indicators that can be used to evaluate the power of the jet. Meanwhile high-angular-resolution X-…
Dynamical Energy Dissipation of Relativistic Magnetic Bullets
Yo Kusafuka, Katsuaki Asano, Takumi Ohmura +1
To demonstrate the magnetic energy dissipation via relativistic shocks, we carry out spherically symmetrical one-dimensional special relativistic magneto-hydrodynamic simulations o…
Non-thermal emissions from a head-tail radio galaxy in 3D magnetohydrodynamic simulations
Takumi Ohmura, Katsuaki Asano, Kosuke Nishiwaki +2
We present magnetohydrodynamic simulations of a jet-wind interaction in a galaxy cluster and the radio to gamma-ray and the neutrino emissions from this "head-tail galaxy". Our sim…
Pseudo-observation of spiral galaxies in the radio band to verify depolarization models
Yuta Tashima, Takumi Ohmura, Mami Machida
Studies of the three-dimensional (3D) structures of galactic magnetic fields are now entering a new era, with broadband, highly sensitive radio observations and new analysis method…
