Gas infall and radial transport in cosmological simulations of milky way-mass discs (2021)
Journal Article
Trapp, C. W., Kereš, D., Chan, T. K., Escala, I., Hummels, C., Hopkins, P. F., …Wetzel, A. (2022). Gas infall and radial transport in cosmological simulations of milky way-mass discs. Monthly Notices of the Royal Astronomical Society, 509(3), 4149-4170. https://doi.org/10.1093/mnras/stab3251

Observations indicate that a continuous supply of gas is needed to maintain observed star formation rates in large, discy galaxies. To fuel star formation, gas must reach the inner regions of such galaxies. Despite its crucial importance for galaxy e...

Which AGN jets quench star formation in massive galaxies? (2021)
Journal Article
Su, K., Hopkins, P. F., Bryan, G. L., Somerville, R. S., Hayward, C. C., Anglés-Alcázar, D., …Kereš, D. (2021). Which AGN jets quench star formation in massive galaxies?. Monthly Notices of the Royal Astronomical Society, 507(1), 175-204. https://doi.org/10.1093/mnras/stab2021

Without additional heating, radiative cooling of the halo gas of massive galaxies (Milky Way-mass and above) produces cold gas or stars exceeding that observed. Heating from active galactic nucleus (AGN) jets is likely required, but the jet propertie... Read More about Which AGN jets quench star formation in massive galaxies?.

Smoothed particle radiation hydrodynamics: two-moment method with local Eddington tensor closure (2021)
Journal Article
Chan, T., Theuns, T., Bower, R., & Frenk, C. (2021). Smoothed particle radiation hydrodynamics: two-moment method with local Eddington tensor closure. Monthly Notices of the Royal Astronomical Society, 505(4), 5784-5814. https://doi.org/10.1093/mnras/stab1686

We present a new smoothed particle hydrodynamics-radiative transfer method (SPH-M1RT) that is coupled dynamically with SPH. We implement it in the (task-based parallel) SWIFT galaxy simulation code but it can be straightforwardly implemented in other...

Virial shocks are suppressed in cosmic ray-dominated galaxy haloes (2021)
Journal Article
Ji, S., Kereš, D., Chan, T., Stern, J., Hummels, C. B., Hopkins, P. F., …Faucher-Giguère, C. (2021). Virial shocks are suppressed in cosmic ray-dominated galaxy haloes. Monthly Notices of the Royal Astronomical Society, 505(1), 259-273. https://doi.org/10.1093/mnras/stab1264

We study the impact of cosmic rays (CRs) on the structure of virial shocks, using a large suite of high-resolution cosmological FIRE-2 simulations accounting for CR injection by supernovae. In Milky Way-mass, low-redshift (z ≲ 1−2) haloes, which are... Read More about Virial shocks are suppressed in cosmic ray-dominated galaxy haloes.

Virialization of the Inner CGM in the FIRE Simulations and Implications for Galaxy Disks, Star Formation, and Feedback (2021)
Journal Article
Stern, J., Faucher-Giguère, C., Fielding, D., Quataert, E., Hafen, Z., Gurvich, A. B., …Hopkins, P. F. (2021). Virialization of the Inner CGM in the FIRE Simulations and Implications for Galaxy Disks, Star Formation, and Feedback. Astrophysical Journal, 911(2), Article 88. https://doi.org/10.3847/1538-4357/abd776

We use the FIRE-2 cosmological simulations to study the formation of a quasi-static, virial-temperature gas phase in the circumgalactic medium (CGM) at redshifts 0 < z < 5 and how the formation of this virialized phase affects the evolution of galact...
