The Effect of Galaxy Interactions on Starbursts in Milky Way-Mass Galaxies in FIRE Simulations
Fei Li, Mubdi Rahman, Norman Murray +5
Simulations and observations suggest that galaxy interactions may enhance the star formation rate (SFR) in merging galaxies. One proposed mechanism is the torque exerted on the gas…
Aggressively-Dissipative Dark Dwarfs: The Effects of Atomic Dark Matter on the Inner Densities of Isolated Dwarf Galaxies
Sandip Roy, Xuejian Shen, Jared Barron +4
We present the first suite of cosmological hydrodynamical zoom-in simulations of isolated dwarf galaxies for a dark sector that consists of Cold Dark Matter and a strongly-dissipat…
Angular momentum transfer in cosmological simulations of Milky Way-mass discs
Cameron W. Trapp, Dušan Kereš, Philip F. Hopkins +2
Fueling star formation in large, discy galaxies requires a continuous supply of gas accreting into star-forming regions. Previously, we characterized this accretion in 4 Milky Way…
Playing with FIRE: A Galactic Feedback-Halting Experiment Challenges Star Formation Rate Theories
Shivan Khullar, Christopher D. Matzner, Norman Murray +4
Stellar feedback influences the star formation rate (SFR) and the interstellar medium of galaxies in ways that are difficult to quantify numerically, because feedback is an essenti…
An Analytic Model For Magnetically-Dominated Accretion Disks
Philip F. Hopkins, Jonathan Squire, Eliot Quataert +6
Recent numerical cosmological radiation-magnetohydrodynamic-thermochemical-star formation simulations have resolved the formation of quasar accretion disks with Eddington or super-…
