The impact of cosmic rays on dynamical balance and disc–halo interaction in L⋆ disc galaxies (2022)
Journal Article
Chan, T., Kereš, D., Gurvich, A. B., Hopkins, P. F., Trapp, C., Ji, S., & Faucher-Giguère, C. (2022). The impact of cosmic rays on dynamical balance and disc–halo interaction in L⋆ disc galaxies. Monthly Notices of the Royal Astronomical Society, 517(1), 597-615. https://doi.org/10.1093/mnras/stac2236

Cosmic rays (CRs) are an important component in the interstellar medium, but their effect on the dynamics of the disc–halo interface (<10 kpc from the disc) is still unclear. We study the influence of CRs on the gas above the disc with high-resolutio... Read More about The impact of cosmic rays on dynamical balance and disc–halo interaction in L⋆ disc galaxies.

Hot-mode accretion and the physics of thin-disc galaxy formation (2022)
Journal Article
Hafen, Z., Stern, J., Bullock, J., Gurvich, A. B., Yu, S., Faucher-Giguère, C., …Hopkins, P. F. (2022). Hot-mode accretion and the physics of thin-disc galaxy formation. Monthly Notices of the Royal Astronomical Society, 514(4), 5056-5073. https://doi.org/10.1093/mnras/stac1603

We use FIRE simulations to study disc formation in z ∼ 0, Milky Way-mass galaxies, and conclude that a key ingredient for the formation of thin stellar discs is the ability for accreting gas to develop an aligned angular momentum distribution via int...

The In Situ Origins of Dwarf Stellar Outskirts in FIRE-2 (2022)
Journal Article
Kado-Fong, E., Sanderson, R. E., Greene, J. E., Cunningham, E. C., Wheeler, C., Chan, T., …Starkenburg, T. (2022). The In Situ Origins of Dwarf Stellar Outskirts in FIRE-2. Astrophysical Journal, 931(2), Article 152. https://doi.org/10.3847/1538-4357/ac6c88

Extended, old, and round stellar halos appear to be ubiquitous around high-mass dwarf galaxies (108.5 < M⋆/M⊙ < 109.6) in the observed universe. However, it is unlikely that these dwarfs have undergone a sufficient number of minor mergers to form ste... Read More about The In Situ Origins of Dwarf Stellar Outskirts in FIRE-2.
