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…
Resolving galaxy formation in the early Universe with BonFIRE and CampFIRE
Jenna Samuel, Michael Boylan-Kolchin, Robert Feldmann +16
The abundance and rapid growth of galaxies at cosmic dawn revealed by the James Webb Space Telescope challenges models of galaxy formation, motivating new simulations to uncover th…
Galaxy Metallicity Gradients in the Reionization Epoch from the FIRE-2 Simulations
Xunda Sun, Xin Wang, Fangzhou Jiang +10
We employ the high-redshift suite of FIRE-2 cosmological hydrodynamic zoom-in simulations to investigate the evolution of gas-phase metallicity radial gradients in galaxies in the…
FORGE'd in the Early Universe: The Effect of Protostellar Outflows on Pop III Accretion
Yasmine J. Meziani, Philip F. Hopkins, Michael Y. GrudiÄ +3
We present a cosmological zoom-in radiation magneto-hydrodynamic (RMHD) simulation, using FORGE'd in FIRE, that follows the formation, growth, and evolution of a single metal-free…
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…
Further correction to the STARFORGE methods paper: Planck-mean dust opacities
Michael Y. GrudiÄ, Dávid Guszejnov, Philip F. Hopkins +2
The model for the Planck-mean dust opacity given in Appendix C of the STARFORGE simulations methods paper does not extrapolate well to low radiation temperature $T_{\rm ra…
