Description

What is gravitational lensing, what has it told us about the universe, and what more can it tell us about the universe? Lenses such as black holes, stars, galaxies, clusters of galaxies, and the universe as a whole will be covered. Concepts such as Einstein rings, photon spheres, image pair creation events, and shear will be defined and briefly discussed. The intersection of gravitational lensing with current research frontiers will be reviewed including how microlensing is being used to search for extra-solar planets, how radio telescopes are being used to probe galaxy-center black holes, and how weak lensing is being used to probe galaxy evolution in the early universe. Possible lensing signals in continuing and upcoming missions such as Planck, DES, LSST, Euclid, and WFIRST will be reviewed. Relevant parts of the lecturer's own research will also be briefly mentioned.
