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…
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…
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…
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…
