Reconnection Studies Under Different Types of Turbulence Driving
Grzegorz Kowal, Alex Lazarian, Ethan T. Vishniac +1
We study a model of fast magnetic reconnection in the presence of weak turbulence proposed by Lazarian and Vishniac (1999) using three-dimensional direct numerical simulations. The…
Global simulations of the magnetic field evolution under the influence of the cosmic-ray-driven dynamo
K. Kulpa-Dybeł, K. Otmianowska-Mazur, B. Kulesza-Żydzik +4
We present three-dimensional global numerical simulations of the cosmic-ray (CR) driven dynamo in barred galaxies. We study the evolution of the interstellar medium of the barred g…
Cosmic ray driven dynamo in barred and ringed galaxies
K. Kulpa-Dybeł, K. Otmianowska-Mazur, B. Kulesza-Żydzik +4
We study the global evolution of the magnetic field and interstellar medium (ISM) of the barred and ringed galaxies in the presence of non-axisymmetric components of the potential,…
Reconnection in weakly stochastic B-fields in 2D
K. Kulpa-Dybel, G. Kowal, K. Otmianowska-Mazur +2
We study two dimensional turbulent magnetic reconnection in a compressible fluid in the gas pressure dominated limit. We use open boundary conditions and start from a Harris curren…
Cosmic-ray driven dynamo in the interstellar medium of irregular galaxies
H. Siejkowski, M. Soida, K. Otmianowska-Mazur +2
Irregular galaxies are usually smaller and less massive than their spiral, S0, and elliptical counterparts. Radio observations indicate that a magnetic field is present in irregula…
Formation of gaseous arms in barred galaxies with dynamically important magnetic field : 3D MHD simulations
B. Kulesza-Zydzik, K. Kulpa-Dybel, K. Otmianowska-Mazur +2
We present results of three-dimensional nonlinear MHD simulations of a large-scale magnetic field and its evolution inside a barred galaxy with the back reaction of the magnetic fi…
