Orbital Polarimetric Tomography of a Flare Near the Sagittarius A* Supermassive Black Hole
One proposed mechanism that produces flares is the formation of compact, bright regions that appear within the accretion disk and close to the event horizon.
Gravitationally Lensed Black Hole Emission Tomography
In this work, we propose BH-NeRF, a novel tomography approach that leverages gravitational lensing to recover the continuous 3D emission field near a black hole.
Interferometric Imaging Directly with Closure Phases and Closure Amplitudes
Closure-only imaging provides results that are as non-committal as possible and allows for reconstructing an image independently from separate amplitude and phase self-calibration.

Reconstructing Video from Interferometric Measurements of Time-Varying Sources
Most recently, the Event Horizon Telescope (EHT) has extended VLBI to short millimeter wavelengths with a goal of achieving angular resolution sufficient for imaging the event horizons of nearby supermassive black holes.
Dynamical Imaging with Interferometry
By linking widely separated radio dishes, the technique of very long baseline interferometry (VLBI) can greatly enhance angular resolution in radio astronomy.
