Comparing Numerical Methods for Isothermal Magnetized Supersonic Turbulence
Alexei G. Kritsuk, Aake Nordlund, David Collins +13
We employ simulations of supersonic super-Alfvenic turbulence decay as a benchmark test problem to assess and compare the performance of nine astrophysical MHD methods actively use…
Magnetic fields during primordial star formation
Dominik R. G. Schleicher, Sharanya Sur, Robi Banerjee +5
Recent FERMI observations provide a lower limit of 10^{-15} G for the magnetic field strength in the intergalactic medium (IGM). This is consistent with theoretical expectations ba…
A new Jeans resolution criterion for (M)HD simulations of self-gravitating gas: Application to magnetic field amplification by gravity-driven turbulence
Christoph Federrath, Sharanya Sur, Dominik R. G. Schleicher +2
Cosmic structure formation is characterized by the complex interplay between gravity, turbulence, and magnetic fields. The processes by which gravitational energy is converted into…
A robust numerical scheme for highly compressible magnetohydrodynamics: Nonlinear stability, implementation and tests
Knut Waagan, Christoph Federrath, Christian Klingenberg
The ideal MHD equations are a central model in astrophysics, and their solution relies upon stable numerical schemes. We present an implementation of a new method, which possesses…
Is the Scaling of Supersonic Turbulence Universal?
Wolfram Schmidt, Christoph Federrath, Ralf Klessen
The statistical properties of turbulence are considered to be universal at sufficiently small length scales, i. e., independent of boundary conditions and large-scale forces acting…
Numerical simulations of compressively driven interstellar turbulence: I. Isothermal gas
Wolfram Schmidt, Christoph Federrath, Markus Hupp +2
We performed numerical simulations of supersonic isothermal turbulence driven by mostly compressive large-scale forcing, using both a static grid and adaptive mesh refinement with…
