Strong Lensing: Lenses and Sources

I will discuss recent studies of both strongly lensed sources, and the foreground lens population (primarily groups and cluster of galaxies), framed by an overview of strong lensing over in the past 30 years, and where I think the field is headed in the next decade. The lensed sources I will detail are primarily selected from the SDSS. Highlights will include the smallest star-forming features ever resolved in a distant galaxy, the new MEGaSaURA atlas of moderate resolution rest-UV spectra of more than a dozen bright lensed galaxies at 1.7<z<3.6, and studies of several lensed AGN. I will also detail an extensive program to test whether the observed strong lensing by massive clusters - particularly that from the South Pole Telescope cluster sample - is consistent with theoretical expectations.
