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…

Implementation of CR Energy SPectrum (CRESP) algorithm in PIERNIK MHD code. I. Spectrally resolved propagation of CR electrons on Eulerian grids

Mateusz Ogrodnik, Michał Hanasz, Dominik Wóltański

We present an efficient algorithm to follow spectral evolution of Cosmic Rays (CR) coupled with an MHD system on Eulerian grids. The algorithm is designed for studies of CR energy…

Streaming instability in the quasi-global protoplanetary discs

Kacper Kowalik, Michal Hanasz, Dominik Wóltański +1

We investigate streaming instability using two-fluid approximation (neutral gas and dust) in a quasi-global, unstratified protoplanetary disc, with the help of PIERNIK code. We com…

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))…
