Why CLEAN when you can PURIFY? A new approach for next-generation radio-interferometric imaging
Rafael E. Carrillo, Jason D. McEwen, Yves Wiaux
In recent works, sparse models and convex optimization techniques have been applied to radio-interferometric (RI) imaging showing the potential to outperform state-of-the-art imagi…

The varying w spread spectrum effect for radio interferometric imaging
Laura Wolz, Filipe B. Abdalla, Rafael E. Carrillo +2
We study the impact of the spread spectrum effect in radio interferometry on the quality of image reconstruction. This spread spectrum effect will be induced by the wide field-of-v…
