The impact of cosmic rays on dynamical balance and disk-halo interaction in Lstar disk galaxies
T. K. Chan, Dusan Keres, Alexander B. Gurvich +4
Cosmic rays (CRs) are an important component in the interstellar medium (ISM), but their effect on the dynamics of the disk-halo interface (< 10 kpc from the disk) is still unclear…
The In-situ Origins of Dwarf Stellar Outskirts in FIRE-2
Erin Kado-Fong, Robyn E. Sanderson, Jenny E. Greene +11
Extended, old, and round stellar halos appear to be ubiquitous around high-mass dwarf galaxies () in the observed universe. However, it is unlike…
Gas infall and radial transport in cosmological simulations of Milky Way-mass disks
Cameron Trapp, Dusan Keres, T. K. Chan +7
Observations indicate that a continuous supply of gas is needed to maintain observed star formation rates in large, disky galaxies. To fuel star formation, gas must reach the inner…
Which AGN Jets Quench Star Formation in Massive Galaxies?
Kung-Yi Su, Philip F. Hopkins, Greg L. Bryan +12
Without additional heating, radiative cooling of gas in the halos of massive galaxies (Milky Way and above) produces cold gas or stars in excess of that observed. Previous work sug…
Smoothed Particle Radiation Hydrodynamics: Two-Moment method with Local Eddington Tensor Closure
T. K. Chan, Tom Theuns, Richard Bower +1
We present a new radiative transfer method (SPH-M1RT) that is coupled dynamically with smoothed particle hydrodynamics (SPH). We implement it in the (task-based parallel) SWIFT gal…
