Lens Modeling

We develop and use GIGA-Lens, the fastest GPU-accelerated lens modeling code, to reconstruct mass distributions of lensing galaxies and clusters. This work enables us to test models of dark matter, galaxy structure, and the expansion of the Universe using strong gravitational lenses with multiple sources or time-delay measurements. We have applied GIGA-Lens to real data, including:
