Tilted supercritical accretion disks around black holes can accrete mass at rates up to ten times the Eddington limit due to standing shocks, unlike untilted disks that respect the limit.

3D simulations recover the critical obliquity for disc breaking predicted by semi-analytic models and reveal additional stabilization by spiral arms that can prevent breaking.
Realistic accretion-disk thickness and warps bias black-hole spin and geometry estimates when iron K-alpha lines are modeled with flat-disk assumptions.
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.
Free neutrons survive r-process freeze-out in fast ejecta of neutron star mergers and their beta-decay heating produces a visible early kilonova precursor for mass fractions above ~0.05.
Turbulent torques modeled as a Gaussian around the linear torque can push gas-induced dephasing in LISA EMRIs above the detection threshold for Eddington ratios above 0.3 and sufficient turbulence strength.

Chaotic migration of LISA Extreme Mass Ratio Inspirals in a turbulent accretion disk: effect on waveform de-phasing
Turbulent torques modeled as a Gaussian around the linear torque can push gas-induced dephasing in LISA EMRIs above the detection threshold for Eddington ratios above 0.3 and sufficient turbulence strength.
