Leonidas Moustakas - Highlights of strong gravitational lensing in Euclid: New insights into galactic structure, stellar IMFs, cosmography, and dark matter.

The Euclid mission will complete a Wide (1/3 of the sky) and a Deep (40 sq. deg) survey over its six years of operations, with depths and imaging quality sufficient for sensitive weak lensing measurements. This data will be ideal for identifying even relatively low mass strong gravitational lensing systems, and some tens of thousands of new systems will be discovered. I will review the properties of the lenses we are expecting to discover (and the techniques being developed to do so), and the most important astronomical applications they will be used for, including maps of galactic structure, precise stellar initial mass functions, independent measurements of dark energy, and dark matter particle property constraints possible through statistics of large numbers of dwarf-galaxy scale dark matter-only halos; each of these measurements will be done at several epochs of cosmic time, for unique insight into their evolution.
