Second public data release of the FIRE-2 cosmological zoom-in simulations of galaxy formation
Andrew Wetzel, Jenna Samuel, Pratik J. Gandhi +34
We describe the second data release (DR2) of the FIRE-2 cosmological zoom-in simulations of galaxy formation, from the Feedback In Realistic Environments (FIRE) project, available…
Density, asymmetry and citation dynamics in scientific literature
Nathaniel Imel, Zachary Hafen
Scientific behavior is often characterized by a tension between building upon established knowledge and introducing novel ideas. Here, we investigate whether this tension is reflec…
Great Balls of FIRE III: Modeling Black Hole Mergers from Massive Star Clusters in Simulations of Galaxies
Tristan Bruel, Carl L. Rodriguez, Astrid Lamberts +3
After the nearly hundred gravitational-wave detections reported by the LIGO-Virgo-KAGRA Collaboration, the question of the cosmological origin of merging binary black holes (BBHs)…
Accretion onto disk galaxies via hot and rotating CGM inflows
Jonathan Stern, Drummond Fielding, Zachary Hafen +5
Observed accretion rates onto the Milky-Way and other local spirals fall short of that required to sustain star formation for cosmological timescales. A potential avenue for this u…
On the Metallicities and Kinematics of the Circumgalactic Media of Damped Ly Systems at
Stephanie M. Urbano Stawinski, Kate H. R. Rubin, J. Xavier Prochaska +7
We use medium- and high-resolution spectroscopy of close pairs of quasars to analyze the circumgalactic medium (CGM) surrounding 32 damped Ly absorption systems (DLAs). The prim…
The Halo21 Absorption Modeling Challenge: Lessons From "Observing" Synthetic Circumgalactic Absorption Spectra
Zachary Hafen, Sameer, Cameron Hummels +7
In the Halo21 absorption modeling challenge we generated synthetic absorption spectra of the circumgalactic medium (CGM), and attempted to estimate the metallicity, temperature, an…
The imprint of bursty star formation on alpha-element abundance patterns in Milky Way-like galaxies
Hanna Parul, Jeremy Bailin, Andrew Wetzel +5
Milky Way-mass galaxies in the FIRE-2 simulations demonstrate two main modes of star formation. At high redshifts star formation occurs in a series of short and intense bursts, whi…
What Causes The Formation of Disks and End of Bursty Star Formation?
Philip F. Hopkins, Alexander B. Gurvich, Xuejian Shen +17
As they grow, galaxies can transition from irregular/spheroidal with 'bursty' star formation histories (SFHs), to disky with smooth SFHs. But even in simulations, the direct physic…
A unified model for the co-evolution of galaxies and their circumgalactic medium: the relative roles of turbulence and atomic cooling physics
Viraj Pandya, Drummond B. Fielding, Greg L. Bryan +7
The circumgalactic medium (CGM) plays a pivotal role in regulating gas flows around galaxies and thus shapes their evolution. However, the details of how galaxies and their CGM co-…
Born this way: thin disc, thick disc, and isotropic spheroid formation in FIRE-2 Milky-Way-mass galaxy simulations
Sijie Yu, James S. Bullock, Alexander B. Gurvich +7
We investigate the formation of Milky-Way-mass galaxies using FIRE-2 LCDM cosmological zoom-in simulations by studying the orbital evolution of stars formed in the main progenitor…
Rapid disc settling and the transition from bursty to steady star formation in Milky Way-mass galaxies
Alexander B. Gurvich, Jonathan Stern, Claude-André Faucher-Giguère +6
Recent observations and simulations indicate substantial evolution in the properties of galaxies with time, wherein rotationally-supported and steady thin discs (like those frequen…
Great Balls of FIRE II: The evolution and destruction of star clusters across cosmic time in a Milky Way-mass galaxy
Carl L. Rodriguez, Zachary Hafen, Michael Y. Grudić +4
The current generation of galaxy simulations can resolve individual giant molecular clouds, the progenitors of dense star clusters. But the evolutionary fate of these young massive…
Great Balls of FIRE I: The formation of star clusters across cosmic time in a Milky Way-mass galaxy
Michael Y. Grudić, Zachary Hafen, Carl L. Rodriguez +5
The properties of young star clusters formed within a galaxy are thought to vary in different interstellar medium (ISM) conditions, but the details of this mapping from galactic to…
Galaxies lacking dark matter produced by close encounters in a cosmological simulation
Jorge Moreno, Shany Danieli, James S. Bullock +18
The standard cold dark matter plus cosmological constant model predicts that galaxies form within dark-matter haloes, and that low-mass galaxies are more dark-matter dominated than…
Public data release of the FIRE-2 cosmological zoom-in simulations of galaxy formation
Andrew Wetzel, Christopher C. Hayward, Robyn E. Sanderson +23
We describe a public data release of the FIRE-2 cosmological zoom-in simulations of galaxy formation, available at http://flathub.flatironinstitute.org/fire, from the Feedback In R…
Hot-mode accretion and the physics of thin-disk galaxy formation
Zachary Hafen, Jonathan Stern, James Bullock +16
We use FIRE simulations to study disk formation in z~0, Milky Way-mass galaxies, and conclude that a key ingredient for the formation of thin stellar disks is the ability for accre…
Amplified J-factors in the Galactic Center for velocity-dependent darkmatter annihilation in FIRE simulations
Daniel McKeown, James S. Bullock, Francisco J. Mercado +6
We use FIRE-2 zoom cosmological simulations of Milky Way size galaxy halos to calculate astrophysical J-factors for dark matter annihilation and indirect detection studies. In addi…
