  • 3D model of magnetic fields evolution in dwarf irregular galaxies 
    Siejkowski, Hubert; Soida, Marian; Otmianowska-Mazur, Katarzyna; Hanasz, Michał; Bomans, Dominik J. (2011-01-12)
    Radio observations show that magnetic fields are present in dwarf irregular galaxies (dIrr) and its strength is comparable to that found in spiral galaxies. Slow rotation, weak shear and shallow gravitational potential are ...
  • 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 the interstellar medium of irregular galaxies 
    Siejkowski, Hubert; Soida, Marian; Otmianowska-Mazur, Katarzyna; Hanasz, Michał; Bomans, Dominik J. (2010-09-27)
    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 irregular galaxies whose value is similar to that ...
  • Cosmic-ray driven dynamo in the medium of irregular galaxy 
    Siejkowski, Hubert; Soida, Marian; Otmianowska-Mazur, Katarzyna; Hanasz, Michał; Bomans, Dominik J. (2009-01-12)
    We investigate the cosmic ray driven dynamo in the interstellar medium of irregular galaxy. The observations (Chyzy et al. 2000, 2003) show that the magnetic field in irregular galaxies is present and its value reaches the ...
