Journal Article

We use smoothed particle hydrodynamics simulations of isolated Milky Way-mass disc galaxies that include cold, interstellar gas to test subgrid prescriptions for star formation (SF). Our fiducial model combines a Schmidt law with a gravitational inst... Read More about Tests of subgrid models for star formation using simulations of isolated disc galaxies.

Rapid disc settling and the transition from bursty to steady star formation in Milky Way-mass galaxies (2022)
Journal Article

Recent observations and simulations indicate substantial evolution in the properties of galaxies with time, wherein rotationally supported and steady thin discs (like those frequently observed in the local Universe) emerge from galaxies that are clum...

Unravelling the physics of multiphase AGN winds through emission line tracers (2021)
Journal Article
Richings, A. J., Faucher-Giguère, C.-A., & Stern, J. (2021). Unravelling the physics of multiphase AGN winds through emission line tracers. Monthly Notices of the Royal Astronomical Society, 503(2), 1568-1585. https://doi.org/10.1093/mnras/stab556

Observations of emission lines in active galactic nuclei (AGNs) often find fast (∼1000 km s−1) outflows extending to kiloparsec scales, seen in ionized, neutral atomic and molecular gas. In this work we present radiative transfer calculations of emis... Read More about Unravelling the physics of multiphase AGN winds through emission line tracers.

The changing circumgalactic medium over the last 10 Gyr I: physical and dynamical properties (2020)
Journal Article

Monthly Notices of the Royal Astronomical Society, 500(1), 1476-1490. https://doi.org/10.1093/mnras/staa3203

We present an analysis of the physical and dynamical states of two sets of EAGLE zoom simulations of galaxy haloes, one at high redshift (z = 2−3) and the other at low redshift (z = 0), with masses of ≈1012 M⊙. Our focus is how the circumgalactic med... Read More about The changing circumgalactic medium over the last 10 Gyr I: physical and dynamical properties.
