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…
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…
Stellar feedback-regulated black hole growth: driving factors from nuclear to halo scales
Lindsey Byrne, Claude-André Faucher-Giguère, Jonathan Stern +4
Several recent simulations of galaxy formation predict two main phases of supermassive black hole (BH) accretion: an early, highly intermittent phase (during which BHs are under-ma…
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…
The effects of local stellar radiation and dust depletion on non-equilibrium interstellar chemistry
Alexander J. Richings, Claude-Andre Faucher-Giguere, Alexander B. Gurvich +2
Interstellar chemistry is important for galaxy formation, as it determines the rate at which gas can cool, and enables us to make predictions for observable spectroscopic lines fro…
Firefly: a browser-based interactive 3D data visualization tool for millions of data points
Alexander B. Gurvich, Aaron M. Geller
We present Firefly, a new browser-based interactive tool for visualizing 3D particle data sets. On a typical personal computer, Firefly can simultaneously render and enable real-ti…
The low redshift Lyman- Forest as a constraint for models of AGN feedback
Blakesley Burkhart, Megan Tillman, Alexander B. Gurvich +5
We study the sensitivity of the Lyman- Forest observables, such as the column density distribution function (CDD), flux PDF, flux power spectrum, and line width distribu…
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…
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…
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 bursty origin of the Milky Way thick disc
Sijie Yu, James S. Bullock, Courtney Klein +11
We investigate thin and thick stellar disc formation in Milky-Way-mass galaxies using twelve FIRE-2 cosmological zoom-in simulations. All simulated galaxies experience an early per…
First Co-spatial Comparison of Stellar, Neutral-, and Ionized-gas Metallicities in a metal-rich galaxy: M83
Svea Hernandez, Alessandra Aloisi, Bethan L. James +14
We carry out a comparative analysis of the metallicities from the stellar, neutral-gas, and ionized-gas components in the metal-rich spiral galaxy M83. We analyze spectroscopic obs…
The time-scales probed by star formation rate indicators for realistic, bursty star formation histories from the FIRE simulations
José A. Flores Velázquez, Alexander B. Gurvich, Claude-André Faucher-Giguère +10
Understanding the rate at which stars form is central to studies of galaxy formation. Observationally, the star formation rates (SFRs) of galaxies are measured using the luminosity…
Virialization of the inner CGM in the FIRE simulations and implications for galaxy discs, star formation and feedback
Jonathan Stern, Claude-André Faucher-Giguère, Drummond Fielding +13
We use the FIRE-2 cosmological simulations to study the formation of a quasi-static, virial-temperature gas phase in the circumgalactic medium (CGM) at redshifts 0<z<5, and how the…
Pressure balance in the multiphase ISM of cosmologically simulated disk galaxies
Alexander B. Gurvich, Claude-André Faucher-Giguère, Alexander J. Richings +13
Pressure balance plays a central role in models of the interstellar medium (ISM), but whether and how pressure balance is realized in a realistic multiphase ISM is not yet well und…
Swirls of FIRE: Spatially Resolved Gas Velocity Dispersions and Star Formation Rates in FIRE-2 Disk Environments
