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. Grudić, 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 rad…
Bridging scales: How much do supermassive black holes grow in the suppressed Bondi regime?
Kung-Yi Su, Angelo Ricarte, Priyamvada Natarajan +6
The co-evolution of supermassive black holes (SMBHs) and their host galaxies remains one of the central open questions in cosmology, rooted in the coupling between accretion, feedb…
The role of galactic winds fueling central starbursts and quasars in the FIRE cosmological simulations
Jonathan Mercedes-Feliz, Daniel Anglés-Alcázar, Boon Kiat Oh +7
Central starbursts and Active Galactic Nuclei (AGN) are thought to be fueled by either galaxy interactions or secular processes in gravitationally unstable discs. We employ cosmolo…
Connecting Cores and Black Hole Dynamics Across Scales: From Globular Clusters to Massive Ellipticals
Kyle Kremer, Newlin C. Weatherford, Philip F. Hopkins +2
The centers of massive elliptical galaxies exhibit a wide range in density profiles, from central cusps to resolved cores with order kiloparsec sizes. The cored ellipticals have be…
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…
Breaking Down the : Toward Modeling and Understanding Globular Cluster Stellar Streams in a Fully Cosmological Context
Nondh Panithanpaisal, Robyn E. Sanderson, Carl L. Rodriguez +7
Next-generation surveys are expected to uncover thousands of globular cluster (GC) stellar streams, motivating the need for a theoretical framework that produces realistic GC strea…
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…
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…
Cosmic Rays Masquerading as Hot CGM Gas: An Inverse-Compton Origin for Diffuse X-ray Emission in the Circumgalactic Medium
Philip F. Hopkins, Eliot Quataert, Sam B. Ponnada +1
Observations have argued that Milky Way (MW), Andromeda, and lower-mass galaxies exhibit extended soft X-ray diffuse halos to radii kpc in the circumgalactic medium…
Central densities of dark matter halos in FIRE-2 simulations of low-mass galaxies with cold dark matter and self-interacting dark matter
Maria C. Straight, Michael Boylan-Kolchin, James S. Bullock +6
We investigate the central density structure of dark matter halos in cold dark matter (CDM) and self-interacting dark matter (SIDM) models using simulations that are part of the Fe…
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,…
