Learning about Aspects of Clusters and Cosmology from Weak and Strong Gravitational Lensing Approaches
I will cover several aspects of current astrophysics that can be probed by various regimes of lensing in simulations and data --from galaxy cluster substructure to what we can learn about cosmology from cluster weak lensing ensembles. Further, a new approach to extracting information from strongly lensed arc images that I have been involved with in recent times, and which is model-independent and has the potential to revolutionize approaches to strong lensing analyses and is very complementary to weak lensing analyses will be introduced. I will further briefly discuss initial lensing results from already-taken data of 6 clusters from the Large Binocular Telescope in Arizona, as well as projections for data coming from the Dark Energy Survey in Chile beginning late in 2011. Last, I will mention the launch of the GREAT10 project, and what potential it has to assist the worldwide lensing community in developing their toolkit for future cosmological analyses.
