  • Can the cosmic-ray driven dynamo model explain the observations of the polarized emission of edge-on galaxies? 
    Otmianowska-Mazur, Katarzyna; Soida, Marian; Kulesza-Żydzik, Barbara; Hanasz, Michał; Kowal, Grzegorz (2008-12-11)
    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 simulations of the dynamo in local Cartesian ...
  • Cosmic-ray driven dynamo in galactic disks 
    Hanasz, Michał; Otmianowska-Mazur, Katarzyna; Lesch, Harald; Kowal, Grzegorz; Soida, Marian; Wóltański, Dominik; Kowalik, Kacper; Pawłaszek, Rafał; Kulesza-Żydzik, Barbara (2008-12-31)
    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 action, leading to the amplification of ...
  • Cosmic ray driven dynamo in barred and ringed galaxies 
    Kulpa-Dybeł, K.; Otmianowska-Mazur, Katarzyna; Kulesza-Żydzik, Barbara; Kowal, Grzegorz; Wóltański, Dominik; Hanasz, Michał; Kowalik, Kacper (2011-01-02)
    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, i.e. the bar and/or the oval perturbations. ...
  • Global simulations of the magnetic field evolution under the influence of the cosmic-ray-driven dynamo 
    Kulpa-Dybeł, K.; Otmianowska-Mazur, Katarzyna; Kulesza-Żydzik, Barbara; Kowal, Grzegorz; Hanasz, Michał; Wóltański, Dominik; Kowalik, Kacper (2011-06-01)
    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 galaxy in the presence of non-axisymmetric ...
