The density variance -- Mach number relation in supersonic, isothermal turbulence
Daniel J. Price, Christoph Federrath, Christopher M. Brunt
We examine the relation between the density variance and the mean-square Mach number in supersonic, isothermal turbulence, assumed in several recent analytic models of the star for…
The generation of strong magnetic fields during the formation of the first stars
Sharanya Sur, Dominik R. G. Schleicher, Robi Banerjee +2
Cosmological hydrodynamical simulations of primordial star formation suggest that the gas within the first star-forming halos is turbulent. This has strong implications on the subs…
Importance of the Initial Conditions for Star Formation - I. Cloud Evolution and Morphology
Philipp Girichidis, Christoph Federrath, Robi Banerjee +1
We present a detailed parameter study of collapsing turbulent cloud cores, varying the initial density profile and the initial turbulent velocity field. We systematically investiga…
Implementing and comparing sink particles in AMR and SPH
Christoph Federrath, Robi Banerjee, Daniel Seifried +2
We implemented sink particles in the Adaptive Mesh Refinement (AMR) code FLASH to model the gravitational collapse and accretion in turbulent molecular clouds and cores. Sink parti…
A comparison between grid and particle methods on the statistics of driven, supersonic, isothermal turbulence
Daniel J. Price, Christoph Federrath
We compare the statistics of driven, supersonic turbulence at high Mach number using FLASH a widely used Eulerian grid-based code and PHANTOM, a Lagrangian SPH code at resolutions…
A method for reconstructing the PDF of a 3D turbulent density field from 2D observations
Christopher M. Brunt, Christoph Federrath, Daniel J. Price
We introduce a method for calculating the probability density function (PDF) of a turbulent density field in three dimensions using only information contained in the projected two-…
