Abstract:

Over the past 2–3 decades, gravitational lensing by galaxy clusters has played key roles in various scientific areas within astronomy and astrophysics. These include, primarily, mapping the otherwise-invisible dark matter distribution in the lens or weighing the clusters for constraining structure formation and cosmology; as well as enabling a deeper view into high-redshift galaxies, thanks to lensing magnification. Over the past five years or so, there have been some new, exciting developments that allow for more unprecedented science using strong lensing — involving lensed transients such as lensed supernovae and caustic crossing events, or lensed gamma-ray bursts, fast radio bursts, and gravitational waves. In this talk I will review some of these advancements, as well as take the opportunity to mention some relevant programs in which we are involved.
