Accelerating the CLEAN algorithm of radio interferometry with convex optimization
Hendrik Müller, Mingyu Hsieh, Sanjay Bhatnagar
In radio-interferometry, we recover an image from an incompletely sampled Fourier data. The de-facto standard algorithm, the Cotton-Schwab CLEAN, is iteratively switching between c…

An Algorithm Architecture for Radio Interferometric Data Processing
S. Bhatnagar, U. Rau, M. Hsieh +2
We present a foundational, scalable algorithm architecture for processing data from aperture synthesis radio telescopes. The analysis leading to the architecture is rooted in the t…
