Bridging Scales in Black Hole Accretion and Feedback: Subgrid Prescription from First Principles
Hyerin Cho, Ben S. Prather, Ramesh Narayan +4
Understanding how supermassive black holes (BHs) couple to their host galaxies across a vast spatial and temporal dynamic range remains a central challenge in galaxy evolution. Usi…
Bridging scales: Modeling suppressed Bondi accretion on black holes and its impact on galaxy growth
Antonio J. Porras-Valverde, Priyamvada Natarajan, Angelo Ricarte +4
The accretion and feedback processes governing supermassive black hole (SMBH) growth span an enormous range of spatial scales, from the Event Horizon to the circumgalactic medium.…
Bridging Scales in Black Hole Accretion and Feedback: Relativistic Jet linking the Horizon to the Host Galaxy
Hyerin Cho, Ben S. Prather, Ramesh Narayan +2
Simulating black hole (BH) accretion and feedback from the horizon to galactic scales is extremely challenging, as it involves a vast range of scales. Recently, our multizone metho…
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…
Variability in Black Hole Accretion: Dependence on Rotational and Magnetic Energy Balance
Hyerin Cho, Ramesh Narayan
Most general relativistic magnetohydrodynamic simulations of black hole (BH) hot accretion flows are initialized with small rotating tori and produce stable jets with only small fl…
Bridging Scales in Black Hole Accretion and Feedback: Magnetized Bondi Accretion in 3D GRMHD
Hyerin Cho, Ben S. Prather, Ramesh Narayan +4
Fueling and feedback couple supermassive black holes (SMBHs) to their host galaxies across many orders of magnitude in spatial and temporal scales, making this problem notoriously…
