Deep Learning VLBI Image Reconstruction with Closure Invariants
Samuel Lai, Nithyanandan Thyagarajan, O. Ivy Wong +2
Interferometric closure invariants, constructed from triangular loops of mixed Fourier components, capture calibration-independent information on source morphology. While a complet…

Interferometric Image Reconstruction using Closure Invariants and Machine Learning
Nithyanandan Thyagarajan, Lucas Hoefs, O. Ivy Wong
Interferometric closure invariants encode calibration-independent details of an object's morphology. Excepting simple cases, a direct backward transformation from closure invariant…
