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…
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…
