Global simulations of galactic dynamo driven by cosmic-rays and exploding magnetized stars
Michał Hanasz, Dominik Wóltański, Kacper Kowalik +1
We conduct global galactic--scale magnetohydrodynamical (MHD) simulations of the cosmic--ray driven dynamo. We assume that exploding stars deposit small--scale, randomly oriented,…
Cosmic-ray driven dynamo in galactic disks
M. Hanasz, K. Otmianowska-Mazur, H. Lesch +6
We present new developments on the Cosmic--Ray driven, galactic dynamo, modeled by means of direct, resistive CR--MHD simulations, performed with ZEUS and PIERNIK codes. The dynamo…
Cosmic ray driven dynamo in galactic disks. A parameter study
Michał Hanasz, Katarzyna Otmianowska-Mazur, Grzegorz Kowal +1
We present a parameter study of the magnetohydrodynamical dynamo driven by cosmic rays in the interstellar medium (ISM) focusing on the efficiency of magnetic field amplification a…
PIERNIK mhd code - a multi-fluid, non-ideal extension of the relaxing-TVD scheme (II)
Michał Hanasz, Kacper Kowalik, Dominik Wóltański +2
We present a new multi-fluid, grid MHD code PIERNIK, which is based on the Relaxing TVD scheme (Jin and Xin, 1995). The original scheme (see Trac & Pen (2003) and Pen et al. (2003)…
PIERNIK mhd code - a multi-fluid, non-ideal extension of the relaxing-TVD scheme (I)
Michał Hanasz, Kacper Kowalik, Dominik Wóltański +1
We present a new multi-fluid, grid MHD code PIERNIK, which is based on the Relaxing TVD scheme. The original scheme has been extended by an addition of dynamically independent, but…
Can the cosmic-ray driven dynamo model explain the observations of the polarized emission of edge-on galaxies ?
Katarzyna Otmianowska-Mazur, Marian Soida, Barbara Kulesza-Żydzik +2
In the present paper we construct maps of polarized synchrotron radio emission of a whole galaxy, based on local models of the cosmic ray (CR) driven dynamo. We perform numerical s…
