How High-Specific-Energy Winds Regulate the Circumgalactic Medium of Dwarf Galaxies
Michael Messere, Greg L. Bryan
We investigate the role of ejective and preventive feedback in dwarf halos using cosmological zoom-in simulations. These simulations use ada…
Evolution of Nuclear Star Cluster in Dwarf Galaxy through Mergers and In-Situ Star Formation
Yongseok Jo, Minyong Jung, Greg L. Bryan +3
Nuclear Star Clusters (NSCs) are dense stellar systems located at the centers of galaxies. Employing Enzo-Abyss, which integrates hydrodynamics with a direct N-body solver, we intr…
Aeos: The Impact of Population III Initial Mass Function and Star-by-Star Models in Galaxy Simulations
Kaley Brauer, Jennifer Mead, John H. Wise +7
We explore the effect of variations in the Population III (Pop III) initial mass function (IMF) and star-by-star feedback on early galaxy formation and evolution using the Aeos sim…
From Primordial Stars to Early Galaxies: A Semi-Analytic Model Calibrated with Aeos and Renaissance
Ryan Hazlett, Jennifer Mead, Eli Visbal +6
We present an extension of our semi-analytic model that follows the formation of Population III stars and their metal-enriched descendants, incorporating dark matter halo merger tr…
Aeos is Mixing it Up: The (In)homogeneity of Metal Mixing Following Population III Star Formation
Jennifer Mead, Kaley Brauer, Greg L. Bryan +7
Stellar surface abundances are records of the state of the gas from which stars formed, and thus trace how individual elements have mixed into the surrounding medium following thei…
Aeos: Transport of Metals from Minihalos following Population III Stellar Feedback
Jennifer Mead, Kaley Brauer, Greg L. Bryan +7
We investigate how stellar feedback from the first stars (Population III) distributes metals through the interstellar and intergalactic medium using the star-by-star cosmological h…
