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…
Strong Evidence for Cosmic Ray-Supported L Galaxy Halos via X-ray \& tSZ Constraints
Sam B. Ponnada, Philip F. Hopkins, Yue Samuel Lu +3
Many state-of-the-art galaxy simulations featuring traditional feedback modes have significant challenges producing enough extended soft X-ray ( keV) emission at R $\si…
Constraining cosmic ray transport models using circumgalactic medium properties and observables
Yue Samuel Lu, Dušan Kereš, Philip F. Hopkins +3
Cosmic rays (CRs) are a pivotal non-thermal component of galaxy formation and evolution. However, the intricacies of CR physics, particularly how they propagate in the circumgalact…
Galactic Center Gamma-Ray Emission in MHD Galaxy Formation Simulations with Full Cosmic Ray Spectra
Isabel S. Sands, Philip F. Hopkins, Sam B. Ponnada +3
The Milky Way's galactic center is a highly dynamical, crowded environment. Gamma ray observations of this region, such as the excess of GeV scale gamma rays observed by Fermi LAT,…
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…
