Title:
Learning about Aspects of Clusters and Cosmology from Weak and Strong
Gravitational Lensing Approaches
Abstract:
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 is model-independent
that has the potential to revolutionize approaches to strong lensing
analyses and is very complementary to weak lensing analyses will be
introduced that I have been involved with in recent times. 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.
