Igniting Galaxy Formation in the Postreionization Universe, II: Nature versus Nurture
Jorge Moreno, Defne Aluç, Eisha López +7
Although the ultraviolet background from reionization is thought to conspire against the smallest halos, some gas-rich halos in the post-reionization Universe still form stars. We…
Beyond Cloud-9: The case for discovering more HI-rich failed halos
Jorge Moreno, Coral Wheeler, Francisco J. Mercado +8
HI-rich starless halos, should they exist, hold great promise for elucidating dark matter halo structure. Yet realizing this potential demands reliable theoretical predictions for…
Enhanced Multiphase Circumgalactic Medium and Gas Cycling in Galaxy Mergers
Maolan Yang, Suoqing Ji, Robert Feldmann +9
We investigate the impact of galaxy mergers on the circumgalactic medium (CGM) using the FIREbox cosmological hydrodynamic simulation. By comparing matched samples of merging and i…
Igniting galaxy formation in the post-reionization universe
Jorge Moreno, Coral Wheeler, Francisco J. Mercado +9
It is widely believed that the ultraviolet background produced during the epoch of reionization conspires against the formation of low-mass galaxies. Indeed, this mechanism is ofte…
The quenched fraction of satellites around simulated Milky Way-mass galaxies
Francisco J. Mercado, Devontae C. Baxter, M. Katy Rodriguez Wimberly +7
We compare satellite quenched fractions across three cosmological simulation suites (FIREbox, the FIRE-2 zoom-ins, and IllustrisTNG50) and observational datasets from SAGA, ELVES,…
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…
Disks no more: the morphology of low-mass simulated galaxies in FIREbox
José A. Benavides, Laura V. Sales, Andrew Wetzel +9
We study the morphology of hundreds of simulated central galaxies in the stellar mass range \msun\, from the FIREbox cosmological volume. We demons…
How invisible stellar halos bias our understanding of ultra-faint galaxies
Coral Wheeler, Jorge Moreno, M. Katy Rodriguez Wimberly +6
We explore how a realistic surface brightness detection limit of mag arcsec for stars at the edges of ultra-faint galaxies affects our ability to infer th…
Effects of galactic environment on size and dark matter content in low-mass galaxies
Francisco J. Mercado, Jorge Moreno, Robert Feldmann +8
We utilize the cosmological volume simulation, FIREbox, to investigate how a galaxy's environment influences its size and dark matter content. Our study focuses on approximately 1,…
The Stellar Kinematics of Void Dwarf Galaxies Using KCWI
Mithi A. C. de los Reyes, Evan N. Kirby, Zhuyun Zhuang +3
Dwarf galaxies located in extremely under-dense cosmic voids are excellent test-beds for disentangling the effects of large-scale environment on galaxy formation and evolution. We…
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…
FIRE-3: Updated Stellar Evolution Models, Yields, & Microphysics and Fitting Functions for Applications in Galaxy Simulations
Philip F. Hopkins, Andrew Wetzel, Coral Wheeler +18
Increasingly, uncertainties in predictions from galaxy formation simulations (at sub-Milky Way masses) are dominated by uncertainties in stellar evolution inputs. In this paper, we…
Exploring metallicity-dependent rates of Type Ia supernovae and their impact on galaxy formation
Pratik. J. Gandhi, Andrew Wetzel, Philip F. Hopkins +3
Type Ia supernovae play a critical role in stellar feedback and elemental enrichment in galaxies. Recent transient surveys like the All-Sky Automated Survey for Supernova (ASAS-SN)…
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…

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 In-situ Origins of Dwarf Stellar Outskirts in FIRE-2
Erin Kado-Fong, Robyn E. Sanderson, Jenny E. Greene +11
Extended, old, and round stellar halos appear to be ubiquitous around high-mass dwarf galaxies () in the observed universe. However, it is unlike…
NGC 6822 as a probe of dwarf galactic evolution
Brent Belland, Evan Kirby, Michael Boylan-Kolchin +1
NGC 6822 is the closest isolated dwarf irregular galaxy to the Milky Way. Its proximity and stellar mass (, large for a dwarf galaxy) allow for a detailed study of it…
Progenitor-mass-dependent yields amplify intrinsic scatter in dwarf-galaxy elemental abundance ratios
Dhruv A. Muley, Coral R. Wheeler, Philip F. Hopkins +3
In hydrodynamic simulations, prevailing subgrid chemical-evolution models often use a single, "IMF-averaged" supernova yield, ignoring variations in elemental abundance ratios (par…
A dark matter profile to model diverse feedback-induced core sizes of CDM haloes
Alexandres Lazar, James S. Bullock, Michael Boylan-Kolchin +11
We analyze the cold dark matter density profiles of 54 galaxy halos simulated with FIRE-2 galaxy formation physics, each resolved within of the halo virial radius. These ha…
