High-resolution GRMHD simulations show that tearing of tilted accretion disks around rapidly spinning supermassive black holes drives order-of-magnitude variability in continuum and broad-line luminosities on months-to-years timescales, explaining changing-look AGN.
The paper advocates for a high-S/N UV spectroscopic survey of quasars to produce a legacy archive enabling detailed CGM, IGM, Milky Way, and AGN outflow studies.
