Galactic Dynamos
Axel Brandenburg, Evangelia Ntormousi
Spiral galaxies, including the Milky Way, have large-scale magnetic fields with significant energy densities. The dominant theory attributes these magnetic fields to a large-scale…
Dissipative magnetic structures and scales in small-scale dynamos
A. Brandenburg, I. Rogachevskii, J. Schober
Small-scale dynamos play important roles in modern astrophysics, especially on Galactic and extragalactic scales. Owing to dynamo action, purely hydrodynamic Kolmogorov turbulence…
Batchelor, Saffman, and Kazantsev spectra in galactic small-scale dynamos
Axel Brandenburg, Hongzhe Zhou, Ramkishor Sharma
The magnetic fields in galaxy clusters and probably also in the interstellar medium are believed to be generated by a small-scale dynamo. Theoretically, during its kinematic stage,…
Dynamo effect in unstirred self-gravitating turbulence
Axel Brandenburg, Evangelia Ntormousi
In many astrophysical environments, self-gravity can generate kinetic energy, which, in principle, is available for driving dynamo action. Using direct numerical simulations, we sh…
Hemispheric handedness in the Galactic synchrotron polarization foreground
Axel Brandenburg, Marcus Brüggen
The large-scale magnetic field of the Milky Way is thought to be created by an alpha-Omega dynamo, which implies that it should have opposite handedness North and South of the Gala…
Application of a helicity proxy to edge-on galaxies
Axel Brandenburg, Ray S. Furuya
We study the prospects of detecting magnetic helicity in galaxies by observing the dust polarization of the edge-on galaxy NGC 891. Our numerical results of mean-field dynamo calcu…
