Supernova feedback in porous photoionized Giant Molecular Clouds
Cheryl S. C. Lau, Ian A. Bonnell, Yueh-Ning Lee +1
We present a new suite of numerical simulations of Type II supernovae (SNe) detonating in Giant Molecular Clouds with a variety of density structures shaped by photoionization feed…
Semi-confined supernova feedback in HII region bubbles
Cheryl S. C. Lau, Ian A. Bonnell
Galactic-scale simulations rely on sub-grid models to provide prescriptions for the coupling between supernova (SN) feedback and the interstellar medium (ISM). Many of these models…
The Role of Magnetic Fields in the Formation of High-Mass Star-Forming Cores
Katerina Sophia Klos, Ian A. Bonnell, Rowan J. Smith
Magnetic fields are often invoked as playing a primary role in star formation and in the formation of high-mass stars. We investigate the effect of magnetic fields on the formation…
Competitive Accretion and the Baryonic Fraction in Galaxies
Ian A. Bonnell
The baryonic fraction of galaxies is observed to vary with the mass of its dark matter (DM) halo. Low-mass galaxies have low baryonic fractions which increase to a maximum for mass…
Hybrid radiation hydrodynamics scheme with adaptive gravity-tree-based pseudo-particles
Cheryl S. C. Lau, Maya A. Petkova, Ian A. Bonnell
HII regions powered by ionizing radiation from massive stars drive the dynamical evolution of the interstellar medium. Fast radiative transfer methods for incorporating photoioniza…
