TreeCol: a novel approach to estimating column densities in astrophysical simulations
Paul C. Clark, Simon C. O. Glover, Ralf S. Klessen
We present TreeCol, a new and efficient tree-based scheme to calculate column densities in numerical simulations. Knowing the column density in any direction at any location in spa…
Is molecular gas necessary for star formation?
S. C. O. Glover, P. C. Clark
On galactic scales, the surface density of star formation appears to be well correlated with the surface density of molecular gas. This has lead many authors to suggest that there…
Modeling CO Emission: II. The Physical Characteristics that Determine the X factor in Galactic Molecular Clouds
Rahul Shetty, Simon C. Glover, Cornelis P. Dullemond +3
We investigate how the X factor, the ratio of H_2 column density (NH2) to velocity-integrated CO intensity (W), is determined by the physical properties of gas in model molecular c…
The effect of dust cooling on low-metallicity star-forming clouds
Gustavo Dopcke, Simon C. O. Glover, Paul C. Clark +1
The theory for the formation of the first population of stars (Pop III) predicts a IMF composed predominantly of high-mass stars, in contrast to the present-day IMF, which tends to…
Approximations for modelling CO chemistry in GMCs: a comparison of approaches
S. C. O. Glover, P. C. Clark
We examine several different simplified approaches for modelling the chemistry of CO in three-dimensional numerical simulations of turbulent molecular clouds. We compare the differ…
Understanding the physics of the X-factor
S. C. O. Glover, M. -M. Mac Low
We study the relationship between the H2 and CO abundances in simulated molecular clouds using a fully dynamical model of magnetized turbulence coupled to a detailed chemical netwo…
