Accurate Extragalactic Magnetic Fields from Faraday Rotation with Optimal Dispersion Measure Estimators
Hilay Shah, Mark Krumholz, Naomi McClure-Griffiths +1
Faraday rotation measures (RMs) are one of our few observational tools for measuring magnetic field strengths in extragalactic systems, but converting an RM to a magnetic field est…
Ripples of Stellar Enrichment (RoSE) - simulating element production and mixing in a Milky Way-mass galactic disc star-by-star
Chuhan Zhang, Mark R. Krumholz, Melissa K. Ness +3
We present the Ripples of Stellar Enrichment (RoSE) simulations, which follow an isolated Milky Way-mass disc galaxy with star-by-star feedback and nucleosynthesis from five physic…
A pan-galaxy study of synthetic giant molecular filaments: a turbulence-dominated life cycle
Zipeng Hu, Ke Wang, Mark R. Krumholz +1
Recent surveys of the Galactic plane have revealed dozens of giant molecular filaments (GMFs), with lengths ranging from tens to hundreds of parsecs, yet their origins and life cyc…
Fundamental limits to orbit reconstruction due to non-conservation of stellar actions in a Milky Way-like simulation
Arunima Arunima, Mark Krumholz, Michael Ireland +2
The conservation of stellar actions is a fundamental assumption in orbit reconstruction studies in the Milky Way. However, the disc is highly dynamic, with time-dependent, non-axis…
Understanding the Mechanisms Behind the Distribution of Galactic Metals
Chuhan Zhang, Zefeng Li, Zipeng Hu +1
The evolution and distribution of metals within galaxies are critical for understanding galactic evolution and star formation processes, but the mechanisms responsible for shaping…
On the limitations of H alpha luminosity as a star formation tracer in spatially resolved observations
Zipeng Hu, Benjamin D. Wibking, Mark R. Krumholz +1
This study examines the limitations of H luminosity as a tracer of star formation rates (SFR) in spatially resolved observations. We carry out high-resolution simulations of a M…
The sub-critical illusion: synthetic Zeeman effect observations from galactic zoom-in simulations
Zipeng Hu, Benjamin D. Wibking, Mark R. Krumholz
Mass-to-flux ratios measured via the Zeeman effect suggest the existence of a transition from a magnetically sub-critical state in HI clouds to a super-critical state in molecular…
High-precision star formation efficiency measurements in nearby clouds
Zipeng Hu, Mark R. Krumholz, Riwaj Pokhrel +1
On average molecular clouds convert only a small fraction epsilon_ff of their mass into stars per free-fall time, but differing star formation theories make contrasting claims for…
Reconstructing three-dimensional densities from two-dimensional observations of molecular gas
Zipeng Hu, Mark R. Krumholz, Christoph Federrath +2
Star formation has long been known to be an inefficient process, in the sense that only a small fraction of the mass of any given gas cloud is converted to stars per c…
