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…
