When source variability is comparable to Kerr geodesic delay spreads, high-inclination fast- and slow-light curves can differ by tens of percent; brisk light retains leading lensing timing more cheaply.

Polarization angle swings in photons near a Kerr black hole during ringdown lock in time to quasi-normal modes with amplitudes up to about 10 degrees.
Equatorial asymmetry in black hole spacetimes twists thick tori, displacing their centers and cusps away from the equatorial plane in the same direction as Keplerian orbits.
Derives shadow width, redshift asymmetry, and flux observables for the Lorentz-violating draining-bathtub acoustic black hole, showing how each observable isolates different combinations of the rotation and violation parameters.
Ray-traced images of rotating dark-matter-dressed black holes show the Einasto model stays close to Kerr while the cored-NFW model produces larger centroid shifts, brightness asymmetry, and visibility changes.

Adaptive ray tracing, image diagnostics, and photon ring signatures of rotating dark-matter-dressed black holes
Ray-traced images of rotating dark-matter-dressed black holes show the Einasto model stays close to Kerr while the cored-NFW model produces larger centroid shifts, brightness asymmetry, and visibility changes.
