abstract
The quest for fundamental limitations on physical processes is old and venerable. Here, we investigate the maximum possible power, or luminosity, that any event can produce. We show, via full nonlinear simulations of Einstein's equations, that there exist initial conditions which give rise to arbitrarily large luminosities. However, the requirement that there is no past horizon in the spacetime seems to limit the luminosity to below the Planck value, ${{\cal L}_\textrm{P}\!=\!c^5/G}$. Numerical relativity simulations of critical collapse yield the largest luminosities observed to date, ${\approx \! 0.2 {\cal L}_\textrm{P}}$. We also present an analytic solution to the Einstein equations which seems to give an unboundedly large luminosity; this will guide future numerical efforts to investigate super-Planckian luminosities.

Nonlinear Dynamics near the Threshold of Gravitational Collapse
Perturbation theory around flat space fails before black hole formation once peak luminosity exceeds ~10^-2 L_Planck; near criticality the spectrum flattens to 1/ω, matching the prediction from discrete self-similarity.

The weight of light: colliding pulses of radiation in General Relativity
Focused pulses of electromagnetic radiation can self-gravitate into black holes and, just below the collapse threshold, into ultracompact horizonless states whose measured compactness exceeds the hoop-conjecture value.

High-energy interactions of charged black holes in full general relativity II: Near-extremal merger remnants and universality with the irreducible mass
Charged black hole collisions near the scattering threshold produce near-extremal remnants (Υ_f = 0.97), radiate up to 31% of the total mass, and show charge-independent thresholds when impact parameters are normalize...

The dynamical response of viscous objects to gravitational waves
First fully relativistic calculation of gravitational wave scattering and oscillation modes of viscous stars: viscosity absorbs high-frequency waves, and maximally viscous, near-maximum-compactness stars mimic black h...
