New constraints on modelling the random magnetic field of the MW
Marcus C. Beck, Alexander M. Beck, Rainer Beck +3
We extend the description of the isotropic and anisotropic random component of the small-scale magnetic field within the existing magnetic field model of the Milky Way from Jansson…
The magnetic field structure of the central region in M31
René Gießübel, Rainer Beck
The Andromeda Galaxy (M31) is the nearest grand-design spiral galaxy. Thus far most studies in the radio regime concentrated on the 10 kpc ring. The central region of M31 has signi…
Do magnetic fields influence gas rotation in galaxies?
Detlef Elstner, Rainer Beck, Oliver Gressel
We aim to estimate the contribution of the radial component of the Lorentz force to the gas rotation in several types of galaxies. Using typical parameters for the exponential scal…
Magnetic fields near the peripheries of galactic discs
E. Mikhailov, A. Kasparova, D. Moss +3
Magnetic fields are observed beyond the peripheries of optically detected galactic discs, while numerical models of their origin and the typical magnitudes are still absent. Previo…
LOFAR Sparse Image Reconstruction
H. Garsden, J. N. Girard, J. L. Starck +77
Context. The LOw Frequency ARray (LOFAR) radio telescope is a giant digital phased array interferometer with multiple antennas distributed in Europe. It provides discrete sets of F…
Enhancement of magnetic fields arising from galactic encounters
David Moss, Dmitri Sokoloff, Rainer Beck +1
Galactic encounters are usually marked by a substantial increase of synchrotron emission of the interacting galaxies compared to the typical emission from similar isolated galaxies…
