The Razor's Edge of Collapse: The Transition Point from Lognormal to Powerlaw in Molecular Cloud PDFs
Blakesley Burkhart, Kye Stalpes, David Collins
We derive an analytic expression for the transitional column density value () between the lognormal and power-law form of the probability distribution function (PDF) in star-f…
A Stochastic Closure for Two-Moment Bulk Microphysics of Warm Clouds: Part II, Validation
David Collins, Boualem Khouider
The representation of clouds and associated processes of rain and snow formation remains one of the major uncertainties in climate and weather prediction models. In a companion pap…
GMC Collisions as Triggers of Star Formation. II. 3D Turbulent, Magnetized Simulations
Benjamin Wu, Jonathan C. Tan, Fumitaka Nakamura +3
We investigate giant molecular cloud (GMCs) collisions and their ability to induce gravitational instability and thus star formation. This mechanism may be a major driver of star f…
Length Scales and Turbulent Properties of Magnetic Fields in Simulated Galaxy Clusters
Hilary Egan, Brian W. O'Shea, Eric Hallman +5
Additional physics beyond standard hydrodynamics is needed to fully model the intracluster medium (ICM); however, as we move to more sophisticated models, it is important to consid…
