Wave Optics Lensing: cosmology and fundamental physics from gravitational and plasma lensing of FRBs and other coherent sources

Ue-Li Pen , Canadian Institute for Theoretical Astro
I describe recent progress in wave optics lensing theory and observation. Picard-Lefschetz theory enables the wave optics inverse problem of reconstructing lens properties from observed interference patterns, including ’tunnelling' from imaginary images. This opens up probing dark matter properties, tests of gravitational theories, measurement of cosmic geometry, and more.
