Cygnus A jointly calibrated and imaged via non-convex optimisation from VLA data
Arwa Dabbech, Audrey Repetti, Rick A. Perley +2
Radio interferometric (RI) data are noisy under-sampled spatial Fourier components of the unknown radio sky affected by direction-dependent antenna gains. Failure to model these an…
Wideband Super-resolution Imaging in Radio Interferometry via Low Rankness and Joint Average Sparsity Models (HyperSARA)
Abdullah Abdulaziz, Arwa Dabbech, Yves Wiaux
We propose a new approach within the versatile framework of convex optimization to solve the radio-interferometric wideband imaging problem. Our approach, dubbed HyperSARA, solves…
Robust dimensionality reduction for interferometric imaging of Cygnus A
S. Vijay Kartik, Arwa Dabbech, Jean-Philippe Thiran +1
Extremely high data rates expected in next-generation radio interferometers necessitate a fast and robust way to process measurements in a big data context. Dimensionality reductio…
