A Nonlinear General Implicit Runge-Kutta Integrator for Multifluid Charged Dust and Gas
Mengxuan Chen, Hui Li, Chong-Chong He +3
Charged dust in magnetized gas is subject to aerodynamic drag and the Lorentz force, both of which can be difficult to model numerically in a fluid simulation where their character…
A novel numerical method for mixed-frame multigroup radiation-hydrodynamics with GPU acceleration implemented in the QUOKKA code
Chong-Chong He, Benjamin D. Wibking, Mark R. Krumholz
Mixed-frame formulations of radiation-hydrodynamics (RHD), where the radiation quantities are computed in an inertial frame but matter quantities are in a comoving frame, are advan…
Formation of Large Circumstellar Discs in Multi-scale, ideal-MHD Simulations of Magnetically Critical Pre-stellar Cores
Chong-Chong He, Massimo Ricotti
The formation of circumstellar discs is a critical step in the formation of stars and planets. Magnetic fields can strongly affect the evolution of angular momentum during prestell…
Bimodal Star Formation in Simulations of Strongly Magnetized Giant Molecular Clouds
Ronan Hix, Chong-Chong He, Massimo Ricotti
We present the results of a set of radiation magnetohydrodynamic simulations of turbulent molecular clouds in which we vary the initial strength of the magnetic field within a rang…
Massive Prestellar Cores in Radiation-magneto-turbulent Simulations of Molecular Clouds
Chong-Chong He, Massimo Ricotti
We simulate the formation and collapse of prestellar cores at few-AU resolution in a set of radiation-magneto-hydrodynamic simulations of giant molecular clouds (GMCs) using the gr…
A Fast and Accurate Analytic Method of Calculating Galaxy Two-point Correlation Functions
Chong-Chong He
We have developed a new analytic method to calculate the galaxy two-point correlation functions (TPCFs) accurately and efficiently, applicable to surveys with finite, regular, and…
Simulating Star Clusters Across Cosmic Time: II. Escape Fraction of Ionizing Photons from Molecular Clouds
Chong-Chong He, Massimo Ricotti, Sam Geen
We calculate the hydrogen and helium-ionizing radiation escaping star-forming molecular clouds, as a function of the star cluster mass and compactness, using a set of high-resoluti…
Simulating Star Clusters Across Cosmic Time: I. Initial Mass Function, Star Formation Rates and Efficiencies
Chong-Chong He, Massimo Ricotti, Sam Geen
We present radiation-magneto-hydrodynamic simulations of star formation in self-gravitating, turbulent molecular clouds, modeling the formation of individual massive stars, includi…
