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: 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…

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…

Doubly Separable Spacetimes and Symmetry Constraints on their Self-Gravitating Matter Content

Prashant Kocherlakota, Ramesh Narayan

A popular approach to constructing exact stationary and axisymmetric nonvacuum solutions in general relativity has been to use solution-generating techniques. Here we revisit a rec…

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…
