Magnetic and gaseous spiral arms in M83
P. Frick, R. Stepanov, R. Beck +4
Isotropic and anisotropic wavelet transforms are used to decompose the images of the spiral galaxy M83 in various tracers to quantify structures in a range of scales from 0.2 to 10…
Current helicity and magnetic field anisotropy in solar active regions
H. Xu, R. Stepanov, K. Kuzanyan +3
The electric current helicity density contains six terms, where are components of the magnetic fie…
Non-Kolmogorov cascade of helicity driven turbulence
Mouloud Kessar, Franck Plunian, Rodion Stepanov +1
We solve the Navier-Stokes equations with two simultaneous forcings. One forcing is applied at a given large-scale and it injects energy. The other forcing is applied at all scales…
Hindered energy cascade in highly helical isotropic turbulence
Rodion Stepanov, Ephim Golbraikh, Peter Frick +1
The conventional approach to the turbulent energy cascade, based on Richardson-Kolmogorov phenomenology, ignores the topology of emerging vortices, which is related to the helicity…
The formation of regular interarm magnetic fields in spiral galaxies
David Moss, Rodion Stepanov, Marita Krause +2
Observations of regular magnetic fields in several nearby galaxies reveal magnetic arms situated between the material arms. The nature of these magnetic arms is a topic of active d…
Measuring magnetism in the Milky Way with the Square Kilometre Array
Marijke Haverkorn, Takuya Akahori, Ettore Carretti +17
Magnetic fields in the Milky Way are present on a wide variety of sizes and strengths, influencing many processes in the Galactic ecosystem such as star formation, gas dynamics, je…
