Redshift drift of gravitational lensing
Piattella, Giani
Investigate the effect of the redshift drift in strong gravitational lensing. The z drift produces a time variation of i) the apparent position of a lensed source and ii) the time delay among incoming signals from different images. Dub these effects as angular drift and time delay drift, respectively, and analyze their relevance in cosmology.
