Evidence for Low Universal Equilibrium Black Hole Spin in Luminous Magnetically Arrested Disks
Beverly Lowell, Jonatan Jacquemin-Ide, Matthew Liska +1
Relativistic collimated outflows, or jets, provide a crucial mode of active galactic nucleus feedback. Although jets extract their energy from the black hole (BH) rotation, their e…

Demystifying flux eruptions: Magnetic flux transport in magnetically arrested disks
Jonatan Jacquemin-Ide, Mitchell C. Begelman, Beverly Lowell +3
Magnetically arrested disks (MADs) are a compelling model for explaining variability in low-luminosity active galactic nuclei (AGN), including horizon-scale outbursts like those ob…

Black Hole Spin-down in Collapsars in 3D Neutrino Transport GRMHD Simulations
Danat Issa, Beverly Lowell, Jonatan Jacquemin-Ide +2
Collapsars -- massive stars whose cores promptly collapse into black holes (BHs) -- can power long-duration gamma-ray bursts (LGRBs) via relativistic, collimated, electromagnetical…
