Deep Learning VLBI Image Reconstruction with Closure Invariants
Deep Learning VLBI Image Reconstruction with Closure Invariants
Interferometric closure invariants, constructed from triangular loops of mixed Fourier components, capture calibration-independent information on source morphology. While a complete set of closure invariants is directly obtainable from measured visibilities, the inverse transformation from closure invariants to the source intensity distribution is not established. In this work, we demonstrate a …
