Iterative removal of sources to model the turbulent electromotive force
Abhijit B. Bendre, Jennifer Schober, Prasun Dhang +1
We describe a novel method to compute the components of dynamo tensors from direct magnetohydrodynamic (MHD) simulations. Our method relies upon an extension and generalisation of…
Small-scale dynamo with finite correlation times
Yann Carteret, Dominik Schleicher, Jennifer Schober
Fluctuation dynamos occur in most turbulent plasmas in astrophysics and are the prime candidates for amplifying and maintaining cosmic magnetic fields. A few analytical models exis…
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…
Observational Signatures of Galactic Turbulent Dynamos
Yann Carteret, Abhijit B. Bendre, Jennifer Schober
We analyse the observational signatures of galactic magnetic fields that are self-consistently generated in magnetohydrodynamic simulations of the interstellar medium through turbu…
Rotation measure and synchrotron emission signatures in simulations of magnetized galactic discs
Yoan Rappaz, Jennifer Schober, Philipp Girichidis
We analyse observational signatures of magnetic fields for simulations of a Milky-Way like disc with supernova-driven interstellar turbulence and self-consistent chemical processes…
The infrared-radio correlation of star-forming galaxies is strongly M-dependent but nearly redshift-invariant since z4
I. Delvecchio, E. Daddi, M. T. Sargent +25
Several works in the past decade have used the ratio between total (rest 8-1000m) infrared and radio (rest 1.4~GHz) luminosity in star-forming galaxies (q), often referre…
Constraining the primordial magnetic field with dwarf galaxy simulations
Mahsa Sanati, Yves Revaz, Jennifer Schober +2
Using a set of cosmological hydro-dynamical simulations, we constrained the properties of primordial magnetic fields by studying their impact on the formation and evolution of dwar…
Tracing star formation with non-thermal radio emission
Jennifer Schober, Dominik R. G. Schleicher, Ralf S. Klessen
A key for understanding the evolution of galaxies and in particular their star formation history will be future ultra-deep radio surveys. While star formation rates (SFRs) are regu…
The Turbulent Dynamo in Highly Compressible Supersonic Plasmas
Christoph Federrath, Jennifer Schober, Stefano Bovino +1
The turbulent dynamo may explain the origin of cosmic magnetism. While the exponential amplification of magnetic fields has been studied for incompressible gases, little is known a…
X-Ray Emission from Star-Forming Galaxies - Signatures of Cosmic Rays and Magnetic Fields
Jennifer Schober, Dominik R. G. Schleicher, Ralf S. Klessen
The evolution of magnetic fields in galaxies is still an open problem in astrophysics. In nearby galaxies the far-infrared-radio correlation indicates the coupling between magnetic…
Magnetic Field Amplification in Young Galaxies
Jennifer Schober, Dominik R. G. Schleicher, Ralf S. Klessen
The Universe at present is highly magnetized, with fields of the order of a few 10^-5 G and coherence lengths larger than 10 kpc in typical galaxies like the Milky Way. We propose…
