No definitive lensing is detected in GW231123, though a potential microlensing feature with modulation amplitude up to 0.8 at 95% confidence is noted, limited by large waveform systematics in short signals.

A Monte Carlo model of a Kerr black hole corona shows that photon collisions create a dense electron-positron pair cloud concentrated near the black hole, yielding X-ray temperatures, Compton parameters, and 4-10% polarization consistent with binary black hole observations.
Time-reversed Shannon entropy distinguishes chaotic from regular orbits in Kerr and Schwarzschild-Melvin spacetimes by quantifying forward-backward asymmetry in probability distributions.
A new public relativistic transfer-function model reltrans for X-ray reverberation mapping that fits both spectra and lags to measure black-hole masses.
External quadrupolar distortion imprints on orbital dynamics and accretion structure in thin disks around deformed compact objects, with the radiating region's outer edge tied to the radiation-to-gas pressure transition.
A Kaluza-Klein boost on Kerr-Taub-NUT enlarges the physical ergoregion volume without altering horizon radius, entropy, or temperature, while adding dyonic work terms to the first law.
Centrifugal and gravitational forces both raise magnetic reconnection rates near Kerr black holes, with gravity separating charges and centrifugal force shortening the current sheet via curved geometry seen by a comoving observer.
Extends intrinsic curvature criteria for massive particle surfaces to stationary spacetimes and demonstrates application to black hole shadows in Kerr-family and Einstein-Maxwell-dilaton solutions.
A review summarizing detection methods, population statistics, and coevolution of supermassive black holes with host galaxies from early universe observations and simulations.
Lecture notes deriving gravitational wave physics from first principles in general relativity for PhD and advanced MSc students.

Pair-Rich Corona of an Accreting Kerr Black Hole
