From Triadic Interactions to Kolmogorov Scaling: A Deterministic, Scale-Resolved Formulation of Energy Flux
Erik Bertram
We develop a deterministic, scale-resolved formulation of energy transfer in the three-dimensional incompressible Navier-Stokes equations based on an explicit triadic decomposition…
A Momentum-Regulated Model For Star Formation Efficiency in Giant Molecular Clouds
Erik Bertram
We present a minimal analytic framework to investigate the star formation efficiency per free-fall time, , in giant molecular clouds (GMCs), focusing on the origin of t…
Synthetic observations of molecular clouds in a galactic center environment: I. Studying maps of column density and integrated intensity
Erik Bertram, Simon C. O. Glover, Paul C. Clark +2
We run numerical simulations of molecular clouds (MCs), adopting properties similar to those found in the Central Molecular Zone (CMZ) of the Milky Way. For this, we employ the mov…
Star formation efficiencies of molecular clouds in a galactic center environment
Erik Bertram, Simon C. O. Glover, Paul C. Clark +1
We use the Arepo moving mesh code to simulate the evolution of molecular clouds exposed to a harsh environment similar to that found in the galactic center (GC), in an effort to un…
Structure analysis of simulated molecular clouds with the Delta-variance
Erik Bertram, Ralf S. Klessen, Simon C. O. Glover
We employ the Delta-variance analysis and study the turbulent gas dynamics of simulated molecular clouds (MCs). Our models account for a simplified treatment of time-dependent chem…
Centroid Velocity Statistics of Molecular Clouds
Erik Bertram, Lukas Konstandin, Rahul Shetty +2
We compute structure functions and Fourier spectra of 2D centroid velocity (CV) maps in order to study the gas dynamics of typical molecular clouds (MCs) in numerical simulations.…
Principal Component Analysis of Molecular Clouds: Can CO reveal the dynamics?
Erik Bertram, Rahul Shetty, Simon C. O. Glover +3
We use Principal Component Analysis (PCA) to study the gas dynamics in numerical simulations of typical MCs. Our simulations account for the non-isothermal nature of the gas and in…
Reliable estimation of the column density in Smoothed Particle Hydrodynamic simulations
Matthew D. Young, Erik Bertram, Nick Moeckel +1
We describe a simple method for estimating the vertical column density in Smoothed Particle Hydrodynamics (SPH) simulations of discs. As in the method of Stamatellos et al. (2007),…
Statistical analysis of the mass-to-flux ratio in turbulent cores: effects of magnetic field reversals and dynamo amplification
Erik Bertram, Christoph Federrath, Robi Banerjee +1
We study the mass-to-flux ratio (M/Φ) of clumps and cores in simulations of supersonic, magnetohydrodynamical turbulence for different initial magnetic field strengths. We investig…
