Magnetic Reconnection in Galaxy Clusters
Takuya Akahori, Kohei Kurahara, Shin-ya Nitta +4
Galaxy clusters contain an intra-cluster medium (ICM) with temperatures of tens of millions of Kelvin. Cosmological structure formation simulations show that this diffuse gas is he…
Effects of magnetic shear and thermodynamic asymmetry on spontaneous MHD magnetic reconnection
Shin-ya Nitta, Koji Kondoh
The spontaneous evolution of magnetic reconnection in generalized situations (with thermodynamic asymmetry regarding the current sheet and magnetic shear) is investigated using two…
Polytropic transonic galactic outflows in a dark matter halo with a central black hole
Asuka Igarashi, Masao Mori, Shin-ya Nitta
Polytropic transonic solutions of spherically symmetric and steady galactic winds in the gravitational potential of a dark matter halo (DMH) with a supermassive black hole (SMBH) a…
A New Concept of Transonic Galactic Outflows in a Cold Dark Matter Halo with a Central Super-Massive Black Hole
Asuka Igarashi, Masao Mori, Shin-ya Nitta
We study fundamental properties of isothermal, steady and spherically symmetric galactic outflow in the gravitational potential of a cold dark matter halo and a central super-massi…
Transonic Galactic Outflows and Their Influences to the Chemical Evolution of Galaxies and Intergalactic Space
Asuka Igarashi, Masao Mori, Shin-ya Nitta
We have categorized possible transonic solutions of galactic outflows in the gravitational potential of DMH and SMBH using the isothermal, spherically symmetric and steady model. W…
Transonic galactic outflows in a dark matter halo with a central black hole and its application to the Sombrero galaxy
Asuka Igarashi, Masao Mori, Shin-ya Nitta
We have classified possible transonic solutions of galactic outflows in the gravitational potential of the dark matter halo (DMH) and super massive black hole (SMBH) under the assu…
Transonic solutions of isothermal galactic winds in a cold dark matter halo
Masami Tsuchiya, Masao Mori, Shin-ya Nitta
We study fundamental properties of steady, spherically symmetric, isothermal galactic outflow in appropriate gravitational potential models. We aim at constructing a universal scal…
Continuous transition from fast magnetic reconnection to slow reconnection and change of the reconnection system structure
Shin-ya Nitta
This paper analytically investigates a series of two-dimensional MHD reconnection solutions over a wide variation of magnetic Reynolds number (). A new series of solution…
Magnetic Reynolds number dependence of reconnection rate and flow structure of the self-similar evolution model of fast magnetic reconnection
Shin-ya Nitta
This paper investigates Magnetic Reynolds number dependence of the ``self-similar evolution model'' (Nitta et al. 2001) of fast magnetic reconnection. I focused my attention on the…
Outflow structure and reconnection rate of the self-similar evolution model of fast magnetic reconnection
Shin-ya Nitta
In order to understand the nature of magnetic reconnection in ``free space'' which is free from any influence of external circumstances, I have studied the structure of spontaneous…
Self-similar solution of fast magnetic reconnection: Semi-analytic study of inflow region
S. Nitta, S. Tanuma, K. Maezawa
An evolutionary process of the fast magnetic reconnection in ``free space'' which is free from any influence of outer circumstance has been studied semi-analytically, and a self-si…
An Application of Kerr Blackhole Fly-Wheel Model to Statistical Properties of QSOs/AGNs
Shin-ya Nitta
The aim of this work is to demonstrate the properties of the magnetospheric model around Kerr blackholes (BHs), so-called the fly-wheel (rotation driven) model. The fly-wheel engin…
