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 the Milky Way star-by-star
Chuhan Zhang, Mark R. Krumholz, Melissa K. Ness +3
We present the Ripples of Stellar Enrichment (RoSE) simulations, which follow a Milky Way-like isolated disc galaxy with star-by-star feedback and nucleosynthesis from all signific…
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…
