We investigate the formation of the satellite galaxy population of a Milky Way-mass halo in a very highly resolved magnetohydrodynamic cosmological zoom-in simulation (baryonic mass resolution mb = 800 M⊙⁠). We show that the properties of the central... Read More about Determining the full satellite population of a Milky Way-mass halo in a highly resolved cosmological hydrodynamic simulation.

PyAutoLens: Open-Source Strong Gravitational Lensing (2021)
Journal Article
Nightingale, J., Hayes, R., Kelly, A., Amvrosiadis, A., Etherington, A., He, Q., Li, N., Cao, X., Frawley, J., Cole, S., Enia, A., Frenk, C., Harvey, D., Li, R., Massey, R., Negrello, M., & Robertson, A. (2021). PyAutoLens: Open-Source Strong Gravitational Lensing. The Journal of Open Source Software, 6(58), Article 2825. https://doi.org/10.21105/joss.02825

Strong gravitational lensing, which can make a background source galaxy appears multiple times due to its light rays being deflected by the mass of one or more foreground lens galaxies, provides astronomers with a powerful tool to study dark matter,...

The origin of X-ray coronae around simulated disc galaxies (2021)
Journal Article
Kelly, A. J., Jenkins, A., & Frenk, C. S. (2021). The origin of X-ray coronae around simulated disc galaxies. Monthly Notices of the Royal Astronomical Society, 502(2), 2934-2951. https://doi.org/10.1093/mnras/stab255

The existence of hot, accreted gaseous coronae around massive galaxies is a long-standing central prediction of galaxy formation models in the ΛCDM cosmology. While observations now confirm that extraplanar hot gas is present around late-type galaxie... Read More about The origin of X-ray coronae around simulated disc galaxies.
