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-messenger Probes of Supermassive Black Hole Spin Evolution
Angelo Ricarte, Priyamvada Natarajan, Ramesh Narayan +1
Using the semi-analytic model Serotina, we investigate the cosmic spin evolution of supermassive black holes incorporating recent results from general relativistic magnetohydrodyna…
Mildly Super-Eddington Accretion Onto Slowly-Spinning Black Holes Explains the X-Ray Weakness of the Little Red Dots
Fabio Pacucci, Ramesh Narayan
JWST has revealed a population of low-luminosity AGN at in compact, red hosts (the "Little Red Dots", or LRDs), which are largely undetected in X-rays. We investigate this ph…
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…
