Collisionless relaxation to equilibrium distributions in cold dark matter halos: origin of the Navarro-Frenk-White profile
Uddipan Banik, Amitava Bhattacharjee
Collisionless self-gravitating systems such as cold dark matter halos are known to harbor universal density profiles despite the intricate non-linear physics of hierarchical struct…
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…
A self-consistent quasilinear theory for collisionless relaxation to universal quasi-steady state attractors in cold dark matter halos
Uddipan Banik, Amitava Bhattacharjee
Collisionless self-gravitating systems, e.g., cold dark matter halos, harbor universal density profiles despite the intricate non-linear physics of hierarchical structure formation…
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…
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…
