Jets from Scratch: Dynamo-Generated Poloidal Magnetic Fields in 3D Collapsar Simulations
Ho-Sang Chan, Ore Gottlieb, 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…
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…

Collapsars - rapidly rotating stellar cores that form black holes - can power gamma-ray bursts (GRBs) and are proposed to be key contributors to the production of heavy elements in…
H-AMR FORGE'd in FIRE I: Magnetic state transitions, jet launching and radiative emission in super-Eddington, highly magnetized quasar disks formed from cosmological initial conditions
Nicholas Kaaz, Matthew Liska, Alexander Tchekhovskoy +2
Quasars are powered by supermassive black hole (SMBH) accretion disks, yet standard disk models are inconsistent with many quasar observations. Recently, Hopkins et al. (2024) simu…
Impact of the disk magnetization on MHD disk wind signature

Observation of blue-shifted X-ray absorption lines indicates the presence of wind from the accretion disk in X-ray binaries. Magnetohydrodynamic (MHD) driving is one of the possibl…
