The statistics and structure of dissipation in subsonic and supersonic turbulence
Edward Troccoli, Christoph Federrath
Turbulence plays a critical role in the atmosphere, oceans, engineering, and astrophysics. The dissipation (heating) induced by turbulent flows is particularly important for the th…
ACES: The Magnetic Field in Large Filaments in the Galactic Center
Dylan M. Paré, Zi-Xuan Feng, Yue Hu +33
The Galactic Center (GC) is an extreme region of the Milky Way that is host to a complex set of thermal and non-thermal structures. In particular, the GC contains high-density gas…
Understanding gas mixing in the circumgalactic medium
Hilay Shah, Freeke van de Voort, Amit Seta +1
We study gas mixing in a simulated Milky Way-mass galaxy's circumgalactic medium (CGM) using cosmological `zoom-in' simulations. We insert tracer dyes in the CGM with different gas…
The spectrum of magnetized turbulence in the interstellar medium
James R. Beattie, Christoph Federrath, Ralf S. Klessen +2
The interstellar medium (ISM) of our Galaxy is magnetized, compressible and turbulent, influencing many key ISM properties, like star formation, cosmic ray transport, and metal and…
A comparison of the turbulent dynamo in weakly-collisional and collisional plasmas: from subsonic to supersonic turbulence
Radhika Achikanath Chirakkara, Christoph Federrath, Amit Seta
Weakly-collisional plasmas, such as the solar wind or the intra-cluster medium (ICM) of galaxy clusters, evolve in the presence of dynamically strong magnetic fields. The turbulent…
So long Kolmogorov: the forward and backward turbulence cascades in a supernovae-driven, multiphase interstellar medium
James R. Beattie, Anne Noer Kolborg, Enrico Ramirez-Ruiz +1
The interstellar medium (ISM) of disk galaxies is turbulent, and yet the fundamental nature of ISM turbulence, the energy cascade, is not understood in detail. In this study, we us…
Magnetized compressible turbulence with a fluctuation dynamo and Reynolds numbers over a million
James R. Beattie, Christoph Federrath, Ralf S. Klessen +2
Supersonic magnetohydrodynamic (MHD) turbulence is a ubiquitous state for many astrophysical plasmas. However, even the basic statistics for this type of turbulence remains uncerta…
Taking control of compressible modes: bulk viscosity and the turbulent dynamo
James R. Beattie, Christoph Federrath, Neco Kriel +2
Many polyatomic astrophysical plasmas are compressible and out of chemical and thermal equilibrium, introducing a bulk viscosity into the plasma via the internal degrees of freedom…
Compressible turbulence in the interstellar medium: New insights from a high-resolution supersonic turbulence simulation
Renaud Ferrand, Sébastien Galtier, Fouad Sahraoui +1
The role of supersonic turbulence in structuring the interstellar medium (ISM) remains an unsettled question. Here, this problem is investigated using a newexact law of compressibl…
A Fluid-Dynamical Subgrid Scale Model for Highly Compressible Astrophysical Turbulence
W. Schmidt, C. Federrath
We formulate and implement the Euler equations with SGS dynamics and provide numerical tests of an SGS turbulence energy model that predicts the turbulent pressure of unresolved ve…
