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…
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…
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…
Filamentary mass accretion towards the high-mass protobinary system G11.92-0.61 MM2
S. Zhang, C. J. Cyganowski, J. D. Henshaw +5
We present deep, sub-arcsecond (2000 AU) resolution ALMA 0.82 mm observations of the former high-mass prestellar core candidate G11.92-0.61 MM2, recently shown to be an $\sim…
Gas and star kinematics in cloud-cloud collisions
James Wurster, Ian A. Bonnell
We model the collision of molecular clouds to investigate the role of the initial properties on the remnants. Our clouds collide and evolve in a background medium that is approxima…
ALMA observations of the Extended Green Object G19.010.03: I. A Keplerian disc in a massive protostellar system
Gwenllian M. Williams, Claudia J. Cyganowski, Crystal L. Brogan +6
Using the Atacama Large Millimetre/submillimeter Array (ALMA) and the Karl G. Jansky Very Large Array (VLA), we observed the Extended Green Object (EGO) G19.010.03 with sub-arcs…
