On the relation between magnetic field strength and gas density in the interstellar medium. II. Density uncertainties and diffuse gas constraints
David Whitworth, Amit Seta, Ralph E. Pudritz +4
The relationship between magnetic field strength and gas density is essential to understand the interstellar medium and star formation. Zeeman measurements in dense atomic and mole…
How is cold, star-forming gas in galaxies affected by magnetic fields?
Kamran R. J. Bogue, Rowan J. Smith, Robin G. Tress +9
Numerical simulations provide a unique opportunity to improve our understanding of the role of magnetic fields in the interstellar medium of galaxies and in star formation. However…
A bottleneck for star formation: the importance of magnetic fields during the formation of cold gas in galaxies
Ryan McGuiness, Rowan J. Smith, David Whitworth
Using a high-resolution simulation of a dwarf galaxy, we quantify the energetic importance of magnetic fields within the different phases of its interstellar medium (ISM) on parsec…
The Noctua Suite of Simulations -- The Difficulty of Growing Massive Black Holes in Low-Mass Dwarf Galaxies
Jonathan Petersson, Michaela Hirschmann, Robin G. Tress +6
Aims. We study the individual and cumulative impact of stellar feedback processes on massive black hole (MBH) growth in a simulated low-mass dwarf galaxy. Methods. A suite of high-…
Do stars still form in molecular gas within CO-dark dwarf galaxies?
David J. Whitworth, Rowan J. Smith, Simon C. O. Glover +6
In the Milky Way and other main-sequence galaxies, stars form exclusively in molecular gas, which is traced by CO emission. However, low metallicity dwarf galaxies are often `CO-da…
Filamentary Molecular Cloud Formation via Collision-induced Magnetic Reconnection in Cold Neutral Medium
Shuo Kong, Rowan J. Smith, David Whitworth +1
We have investigated the possibility of molecular cloud formation via the Collision-induced Magnetic Reconnection (CMR) mechanism of the cold neutral medium (CNM). Two atomic gas c…
On the relation between magnetic field strength and gas density in the interstellar medium: A multiscale analysis
D. J. Whitworth, S. Srinivasan, R. E. Pudritz +19
The magnetic field strength to gas density relation in the interstellar medium is of fundamental importance. We present and compare Bayesian analyses of the B-n relation for two co…
Magnetic field morphology and evolution in the Central Molecular Zone and its effect on gas dynamics
R. G. Tress, M. C. Sormani, P. Girichidis +34
The interstellar medium in the Milky Way's Central Molecular Zone (CMZ) is known to be strongly magnetised, but its large-scale morphology and impact on the gas dynamics are not we…
On the distribution of the Cold Neutral Medium in galaxy discs
Rowan J. Smith, Robin Tress, Juan D. Soler +6
The Cold Neutral Medium (CNM) is an important part of the galactic gas cycle and a precondition for the formation of molecular and star forming gas, yet its distribution is still n…
Filament Formation via Collision-induced Magnetic Reconnection -- Formation of a Star Cluster
Shuo Kong, David Whitworth, Rowan J. Smith +1
A collision-induced magnetic reconnection (CMR) mechanism was recently proposed to explain the formation of a filament in the Orion A molecular cloud. In this mechanism, a collisio…
Magnetic fields do not suppress global star formation in low metallicity dwarf galaxies
David J. Whitworth, Rowan J. Smith, Ralf S. Klessen +5
Many studies concluded that magnetic fields suppress star formation in molecular clouds and Milky Way like galaxies. However, most of these studies are based on fully developed fie…
Is the molecular KS relationship universal down to low metallicities?
David J. Whitworth, Rowan J. Smith, Robin Tress +4
In recent years it has been speculated that in extreme low metallicity galactic environments, stars form in regions that lack H2. In this paper we investigate how changing the meta…
