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…
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…
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…
