Dynamic Black-hole Emission Tomography with Physics-informed Neural Fields

ArXi:2602.08029v2 Announce Type: replace-cross With the success of static black-hole imaging, the next frontier is the dynamic and 3D imaging of black holes. Recovering the dynamic 3D gas near a black hole would reveal previously-unseen parts of the universe and inform new physics models. However, only sparse radio measurements from a single viewpoint are possible, making the dynamic 3D reconstruction problem significantly ill-posed.
