Identifying Anomalies in Gravitational Lens Time Delays
Arthur B. Congdon, Charles R. Keeton, C. Erik Nordgren
We examine the ability of gravitational lens time delays to reveal complex structure in lens potentials. In Congdon, Keeton & Nordgren (2008), we predicted how the time delay betwe…

Analytic Relations for Magnifications and Time Delays in Gravitational Lenses with Fold and Cusp Configurations
Arthur B. Congdon, Charles R. Keeton, C. Erik Nordgren
Gravitational lensing provides a unique and powerful probe of the mass distributions of distant galaxies. Four-image lens systems with fold and cusp configurations have two or thre…
