Momentum feedback from marginally-resolved HII regions in isolated disc galaxies
Sarah M. R. Jeffreson, Mark R. Krumholz, Yusuke Fujimoto +4
We present a novel, physically-motivated sub-grid model for HII region feedback within the moving mesh code Arepo, accounting for both the radiation pressure-driven and thermal exp…
A scaling relation for the molecular cloud lifetime in Milky Way-like galaxies
Sarah M. R. Jeffreson, Benjamin W. Keller, Andrew J. Winter +4
We study the time evolution of molecular clouds across three Milky Way-like isolated disc galaxy simulations at a temporal resolution of 1 Myr, and at a range of spatial resolution…
The role of galactic dynamics in shaping the physical properties of giant molecular clouds in Milky Way-like galaxies
Sarah M. R. Jeffreson, J. M. Diederik Kruijssen, Benjamin W. Keller +2
We examine the role of the large-scale galactic-dynamical environment in setting the properties of giant molecular clouds in Milky Way-like galaxies. We perform three high-resoluti…
The lifecycle of molecular clouds in nearby star-forming disc galaxies
Mélanie Chevance, J. M. Diederik Kruijssen, Alexander P. S. Hygate +29
It remains a major challenge to derive a theory of cloud-scale ( pc) star formation and feedback, describing how galaxies convert gas into stars as a function of the g…
The dynamical evolution of molecular clouds near the Galactic Centre - II. Spatial structure and kinematics of simulated clouds
J. M. D. Kruijssen, J. E. Dale, S. N. Longmore +16
The evolution of molecular clouds in galactic centres is thought to differ from that in galactic discs due to a significant influence of the external gravitational potential. We pr…
On the physical mechanisms governing the cloud lifecycle in the Central Molecular Zone of the Milky Way
S. M. R. Jeffreson, J. M. D. Kruijssen, M. R. Krumholz +1
We apply an analytic theory for environmentally-dependent molecular cloud lifetimes to the Central Molecular Zone of the Milky Way. Within this theory, the cloud lifetime in the Ga…
