Abstract

We propose a scalable, randomised algorithm to solve the inverse imaging problem in wide-band radio- interferometry. In the big-data context of the next- generation radio-telescopes, the scalability is paramount due to the large-scale of the problem to be solved. The proposed method distributes the data measured at each frequency and processes it in parallel. We showcase the algorithm capabilities through realistic simulations.
