  • 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 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 ...
  • Global simulations of galactic dynamo driven by cosmic-rays and exploding magnetized stars 
    Hanasz, Michał; Wóltański, Dominik; Kowalik, Kacper; Pawłaszek, Rafał (2008-12-31)
    We conduct global galactic--scale magnetohydrodynamical (MHD) simulations of the cosmic--ray driven dynamo. We assume that exploding stars deposit small--scale, randomly oriented, dipolar magnetic fields into the differentially ...
  • Stability of three-dimensional relativistic jets: implications for jet collimation 
    Perucho, Manuel; Marti, Jose-Maria; Cela, J. M.; Hanasz, Michał; de la Cruz, R.; Rubio, F. (2010-05-24)
    The stable propagation of jets in FRII sources is remarkable if one takes into account that large-scale jets are subjected to potentially highly disruptive three-dimensional (3D) Kelvin-Helmholtz instabilities. Numerical ...
