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…
Hooks, Lines, and Sinkers: How AGN Feedback and Cosmic-Ray Transport shape the Far Infrared-Radio Correlation of Galaxies
Sam B. Ponnada, Rachel K. Cochrane, Philip F. Hopkins +7
The far-infrared (FIR) - radio correlation (FRC) is one of the most promising empirical constraints on the role of cosmic-rays (CRs) and magnetic fields (\textbf{B}) in galaxy form…
Cosmological predictions for minor axis stellar density profiles in the inner regions of Milky Way-mass galaxies
Madeline Lucey, Robyn Sanderson, Danny Horta +5
CDM cosmology predicts the hierarchical formation of galaxies which build up mass by merger events and accreting smaller systems. The stellar halo of the Milky Way has proven to…
The physical origin of positive metallicity radial gradients in high-redshift galaxies: insights from the FIRE-2 cosmological hydrodynamic simulations
Xunda Sun, Xin Wang, Xiangcheng Ma +11
Using the FIRE-2 cosmological zoom-in simulations, we investigate the temporal evolution of gas-phase metallicity radial gradients of Milky Way-mass progenitors in the redshift ran…
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…
Any Way the Wind Blows: Quantifying Superbubbles and their Outflows in Simulated Galaxies across
Lori E. Porter, Matthew E. Orr, Blakesley Burkhart +4
We present an investigation of clustered stellar feedback in the form of superbubbles identified within eleven galaxies from the FIRE-2 (Feedback in Realistic Environments) cosmolo…
From Seeds to Supermassive Black Holes: Capture, Growth, Migration, and Pairing in Dense Proto-Bulge Environments
Yanlong Shi, Kyle Kremer, Philip F. Hopkins
The origins and mergers of supermassive black holes (BHs) remain a mystery. We describe a scenario from a novel multi-physics simulation featuring rapid (Myr) hyper-E…
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…
Confronting the Diversity Problem: The Limits of Galaxy Rotation Curves as a tool to Understand Dark Matter Profiles
Isabel S. Sands, Philip F. Hopkins, Xuejian Shen +9
While galaxy rotation curves provide one of the most powerful methods for measuring dark matter profiles in the inner regions of rotation-supported galaxies, at the dwarf scale the…
The Importance of Subtleties in the Scaling of the 'Terminal Momentum' For Galaxy Formation Simulations
Philip F. Hopkins
In galaxy formation simulations, it is increasingly common to represent supernovae (SNe) at finite resolution (when the Sedov-Taylor phase is unresolved) via hybrid energy-momentum…
Size-Mass Relations for Simulated Low-Mass Galaxies: Mock Imaging versus Intrinsic Properties
Courtney Klein, James S. Bullock, Jorge Moreno +4
The observationally-inferred size versus stellar-mass relationship (SMR) for low-mass galaxies provides an important test for galaxy formation models. However, the relationship rel…
Cold Gas Subgrid Model (CGSM): A Two-Fluid Framework for Modeling Unresolved Cold Gas in Galaxy Simulations
Iryna S. Butsky, Cameron B. Hummels, Philip F. Hopkins +2
The cold () component of the circumgalactic medium (CGM) accounts for a significant fraction of all galactic baryons. However, using current galaxy-scale simu…
