Abstract

This talk consists of two parts. In the first I argue why (and how) we want to use LOFAR to search for gravitational lenses. The potential to find new radio lenses with extended sources is high, but so are the challenges.

In the second part I discuss the subject of deconvolution in radio interferometry, both for lensing studies and for general applications. I show that standard smoothness constraints that work so well for optical observations completely fail in radio interferometry, and discuss possible alternatives.
