Cygnus A super-resolved via convex optimisation from VLA data
Arwa Dabbech, Alexandru Onose, Abdullah Abdulaziz +3
We leverage the Sparsity Averaging Reweighted Analysis (SARA) approach for interferometric imaging, that is based on convex optimisation, for the super-resolution of Cyg A from obs…
PURIFYing real radio interferometric observations
Luke Pratley, Jason D. McEwen, Mayeul d'Avezac +3
Next-generation radio interferometers, such as the Square Kilometre Array (SKA), will revolutionise our understanding of the universe through their unprecedented sensitivity and re…
An accelerated splitting algorithm for radio-interferometric imaging: when natural and uniform weighting meet
Alexandru Onose, Arwa Dabbech, Yves Wiaux
Next generation radio-interferometers, like the Square Kilometre Array, will acquire tremendous amounts of data with the goal of improving the size and sensitivity of the reconstru…
A randomised primal-dual algorithm for distributed radio-interferometric imaging
Alexandru Onose, Rafael E. Carrillo, Jason D. McEwen +1
Next generation radio telescopes, like the Square Kilometre Array, will acquire an unprecedented amount of data for radio astronomy. The development of fast, parallelisable or dist…
Robust sparse image reconstruction of radio interferometric observations with purify
Luke Pratley, Jason D. McEwen, Mayeul d'Avezac +3
Next-generation radio interferometers, such as the Square Kilometre Array (SKA), will revolutionise our understanding of the universe through their unprecedented sensitivity and re…
Scalable splitting algorithms for big-data interferometric imaging in the SKA era
Alexandru Onose, Rafael E. Carrillo, Audrey Repetti +4
In the context of next generation radio telescopes, like the Square Kilometre Array, the efficient processing of large-scale datasets is extremely important. Convex optimisation ta…
