GRRMHD simulations of TDE debris disks reveal thermal instability and collapse within weeks, producing soft X-ray excess followed by a sharp luminosity drop that resembles AT2021ehb observations.
Realistic accretion-disk thickness and warps bias black-hole spin and geometry estimates when iron K-alpha lines are modeled with flat-disk assumptions.
FIRE-2 simulations with gravitational torque-driven and free-fall accretion models predict enough high-redshift AGN to explain little red dots, with a super-Eddington Eddington-limited scenario for M_BH >= 2e5 Msun in M_star >= 2e7 Msun galaxies reproducing key observations.

Little Red Dots on FIRE: The Ability of Bursty Galaxies to Host an Abundant Population of High-Redshift AGN
FIRE-2 simulations with gravitational torque-driven and free-fall accretion models predict enough high-redshift AGN to explain little red dots, with a super-Eddington Eddington-limited scenario for M_BH >= 2e5 Msun in M_star >= 2e7 Msun galaxies reproducing key observations.
