Global Optimization methods for Gravitational Lens Systems with Regularized Sources
Adam Rogers, Jason D. Fiege
Several approaches exist to model gravitational lens systems. In this study, we apply global optimization methods to find the optimal set of lens parameters using a genetic algorit…

Strong Gravitational Lens Modeling with Spatially Variant Point Spread Functions
Adam Rogers, Jason D. Fiege
Astronomical instruments generally possess spatially variant point-spread functions, which determine the amount by which an image pixel is blurred as a function of position. Severa…

Gravitational Lens Modeling with Genetic Algorithms and Particle Swarm Optimizers
Adam Rogers, Jason D. Fiege
Strong gravitational lensing of an extended object is described by a mapping from source to image coordinates that is nonlinear and cannot generally be inverted analytically. Deter…
