Energy cascade and scaling in supersonic isothermal turbulence
Alexei G. Kritsuk, Rick Wagner, Michael L. Norman
Supersonic turbulence plays an important role in a number of extreme astrophysical and terrestrial environments, yet its understanding remains rudimentary. We use data from a three…
Flux Correlations in Supersonic Isothermal Turbulence
Rick Wagner, Gregory Falkovich, Alexei G. Kritsuk +1
Using data from a large-scale three-dimensional simulation of supersonic isothermal turbulence, we have tested the validity of an exact flux relation derived analytically from the…
Profiles of Dark Matter Velocity Anisotropy in Simulated Clusters
Doron Lemze, Rick Wagner, Yoel Rephaeli +6
We report statistical results for dark matter (DM) velocity anisotropy, β, from a sample of some 6000 cluster-size halos (at redshift zero) identified in a ΛCDM hydrodynamical adap…
Quantifying the collisionless nature of dark matter and galaxies in A1689
Doron Lemze, Yoel Rephaeli, Rennan Barkana +3
We use extensive measurements of the cluster A1689 to assess the expected similarity in the dynamics of galaxies and dark matter (DM) in their motion as collisionless `particles' i…
On the Density Distribution in Star-forming Interstellar Clouds
Alexei G. Kritsuk, Michael L. Norman, Rick Wagner
We use deep adaptive mesh refinement simulations of isothermal self-gravitating supersonic turbulence to study the imprints of gravity on the mass density distribution in molecular…
Turbulent Motions and Shocks Waves in Galaxy Clusters simulated with AMR
F. Vazza, G. Brunetti, A. Kritsuk +3
We have implemented an Adaptive Mesh Refinement criterion explicitly designed to increase spatial resolution around discontinuities in the velocity field in ENZO cosmological simul…
