Bridging Scales: Coupling the galactic nucleus to the larger cosmic environment
Kung-Yi Su, Priyamvada Natarajan, Hyerin Cho +4
Coupling black hole (BH) feeding and feedback involves interactions across vast spatial and temporal scales that is computationally challenging. Tracking gas inflows and outflows f…
Self-regulation of high-redshift black hole accretion via jets: challenges for SMBH formation
Kung-Yi Su, Greg Bryan, Zoltán Haiman
The early growth of black holes (BHs) in atomic-cooling halos is likely influenced by feedback on the surrounding gas. While the effects of radiative feedback are well-documented,…
Where is the Super-Virial Gas? The Supply from hot inflows
Manami Roy, Kung-Yi Su, Smita Mathur +1
In an effort to understand the presence of super-virial gas detected in the Milky Way, we present our findings from isolated galaxy simulations of Milky Way-like systems using GIZM…
The All-Sky Impact of the LMC on the Milky Way Circumgalactic Medium
Christopher Carr, Greg L. Bryan, Nicolás Garavito-Camargo +3
The first infall of the LMC into the Milky Way (MW) represents a large and recent disruption to the MW circumgalactic medium (CGM). In this work, we use idealized, hydrodynamical s…
Unravelling the role of merger histories in the population of In situ stars: linking IllustrisTNG cosmological simulation to H3 survey
Razieh Emami, Lars Hernquist, Randall Smith +16
We undertake a comprehensive investigation into the distribution of in~situ stars within Milky Way-like galaxies, leveraging TNG50 simulations and comparing their predictions with…
Multi-Zone Modeling of Black Hole Accretion and Feedback in 3D GRMHD: Bridging Vast Spatial and Temporal Scales
Hyerin Cho, Ben S. Prather, Kung-Yi Su +2
Simulating accretion and feedback from the horizon scale of supermassive black holes (SMBHs) out to galactic scales is challenging because of the vast range of scales involved. Ela…
