The angular momentum structure of cosmic ray driven galactic outflows triggered by stream accretion
Nicolas Peschken, Michał Hanasz, Thorsten Naab +2
We investigate the impact of gas accretion in streams on the evolution of disc galaxies, using magneto-hydrodynamic simulations including advection and anisotropic diffusion of cos…
Cosmic-ray driven dynamo in galaxies
Michał Hanasz, Dominik Wóltański, Kacper Kowalik +1
We present recent developments of global galactic-scale numerical models of the Cosmic Ray (CR) driven dynamo, which was originally proposed by Parker (1992). We conduct a series o…
Global galactic dynamo driven by cosmic-rays and exploding magnetized stars
Michał Hanasz, Dominik Wóltański, Kacper Kowalik
We report first results of first global galactic-scale CR-MHD simulations of cosmic-ray-driven dynamo. We investigate the dynamics of magnetized interstellar medium (ISM), which is…
PIERNIK mhd code - a multi-fluid, non-ideal extension of the relaxing-TVD scheme (IV)
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 (Jin & Xin, 1995). The original scheme (see Trac & Pen (2003) and Pen et al. (2003))…
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…
