A neural-field reconstruction joined 116 VLBA epochs into a continuous model of 3C 345, mapping apparent superluminal motion while exposing important interpolation limits.
Astronomers did not film the jet of 3C 345 continuously for 27 years. They observed it 116 times between 1995 and 2022, then used a neural representation to infer one changing radio image consistent … [+6629 chars]
