Magnetically Arrested Accretion and Black Hole Spin in a Semi-Analytic Model of Galaxy Formation
Antonio J. Porras-Valverde, Angelo Ricarte, Priyamvada Natarajan +4
We present {\sc Mad Sage}, a semi-analytic model of galaxy formation that couples black hole mass and spin evolution to gas accretion and AGN feedback under magnetically arrested d…
Bridging Scales: Multi-Zone GRMHD-Informed Anisotropic AGN Feedback in Galaxies
Kung-Yi Su, Hyerin Cho, Priyamvada Natarajan +6
We present a galaxy-scale black hole (BH) accretion and feedback model incorporating results from multi-zone general relativistic magnetohydrodynamic (GRMHD) simulations spanning t…
How does a galaxy's quenching probability depend on its black hole's mass?
Antonio J. Porras-Valverde, John C. Forbes
We develop a parametric toy model to explore how black hole mass scatter and the dependence of the quenching probability per unit time on black hole mass, parameterize…
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…
Tracking the assembly of supermassive black holes: a comparison of diverse models across cosmic time
Antonio J. Porras-Valverde, Angelo Ricarte, Priyamvada Natarajan +3
Galaxies grow alongside their central supermassive black holes (SMBHs), linked through fueling and feedback. However, the origins and details of this co-evolution remain unclear an…
On the signature of black holes on the quenched stellar mass function
Antonio J. Porras-Valverde, John C. Forbes
As star-forming galaxies approach or exceed a stellar mass around , they are increasingly likely to be quenched in a process generically called mass quenching. Cen…
The redshift evolution of the scaling relation: new insights from cosmological simulations and semi-analytic models
Shashank Dattathri, Priyamvada Natarajan, Antonio J. Porras-Valverde +4
We study the co-evolution of black holes (BHs) and their host galaxies in the ASTRID and Illustris-TNG300 cosmological simulations and the Dark Sage Semi-Analytic Model (SAM), focu…
Why do semi-analytic models predict higher scatter in the stellar mass-halo mass relation than cosmological hydrodynamic simulations?
Antonio J. Porras-Valverde, John C. Forbes, Rachel S. Somerville +4
Semi-analytic models (SAMs) systematically predict higher stellar-mass scatter at a given halo mass than hydrodynamical simulations and most empirical models. Our goal is to invest…
Angular momentum and morphological sequence of massive galaxies through Dark Sage
Antonio J. Porras-Valverde, Kelly Holley-Bockelmann, Andreas A. Berlind +1
We study the present-day connection between galaxy morphology and angular momentum using the {\sc Dark Sage} semi-analytic model of galaxy formation. For galaxies between $ 10^{11}…
