Untangling Similarities and Differences in Star Formation Histories Across Cosmological Simulations
Alicia M. Savelli, Matthew A. Kustec, Joshua S. Speagle +5
How galaxies assemble depends on processes ranging from small-scale baryonic physics to large-scale cosmological assembly, which are difficult to disentangle with observations alon…
Radiation pressure powers quasar broad absorption line winds but fails to drive galaxy feedback
Braden Seefeldt-Gail, Lluís Mas-Ribas, Norman Murray
Most cosmological simulations invoke quasar-driven winds as the primary mechanism quenching star formation in massive galaxies, assuming wind momentum flux approaches the radiation…
Star Formation Mitosis: The Effects of Particle Splitting on the Star Formation Outcome
Shivan Khullar, Michael Y. Grudić, Christopher D. Matzner +3
Particle splitting can increase the dynamic range in Lagrangian astrophysical simulations by several orders of magnitude. However, such methods can introduce numerical noise that m…
Formation of black hole stars via star--black hole collisions
Yanlong Shi, Qingru Hu, Zhenghao Xu +2
In dense stellar environments such as globular clusters and active galactic nucleus (AGN) disks, stellar-mass black holes (sBHs) may frequently collide with massive stars. We inves…
Dynamical formation of high-eccentricity compact binaries through BH--BH*/TZO collisions
Qingru Hu, Yanlong Shi, Douglas N. C. Lin +1
The rapidly accumulating discoveries of binary stellar-mass black-hole (sBH) coalescences, detected by LIGO, have opened a new window into the formation and evolution of compact bi…
Stellar mergers and chemical element mixing: implications for the metamorphic stellar evolution in AGN disks
Yanlong Shi, Xiaoshan Huang, Douglas N. C. Lin +1
Chemical mixing during stellar mergers can significantly influence the subsequent evolution of the merger remnant. We perform a suite of three-dimensional hydrodynamical simulation…
The In Situ Growth of Stellar-mass "Light" Seed Black Holes in Nuclear Star Clusters
Yanlong Shi, Norman Murray
Remnant black holes (BHs) of massive stars (``light seeds'') are a potential origin for supermassive black holes (SMBHs). We use magnetohydrodynamic simulations to study the format…
Zooming In On The Multi-Phase Structure of Magnetically-Dominated Quasar Disks: Radiation From Torus to ISCO Across Accretion Rates
Philip F. Hopkins, Kung-Yi Su, Norman Murray +12
Recent radiation-thermochemical-magnetohydrodynamic simulations resolved formation of quasar accretion disks from cosmological scales down to ~300 gravitational radii , argu…
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…
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…
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…
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-…
FORGE'd in FIRE II: The Formation of Magnetically-Dominated Quasar Accretion Disks from Cosmological Initial Conditions
Philip F. Hopkins, Jonathan Squire, Kung-Yi Su +9
In a companion paper, we reported the self-consistent formation of quasar accretion disks with inflow rates down to <300 Schwarzschild radii fro…
Formation of Globular Cluster Candidates in Merging Proto-galaxies at High Redshift: A View from the FIRE Cosmological Simulations
Ji-hoon Kim, Xiangcheng Ma, Michael Y. Grudić +7
Using a state-of-the-art cosmological simulation of merging proto-galaxies at high redshift from the FIRE project, with explicit treatments of star formation and stellar feedback i…
