Description
All signals in the Universe are at least weakly lensed, and a fraction of them will be strongly lensed. The probability of strong lensing only becomes larger at higher redshift and, therefore, LISA sources such as massive black hole binaries and extreme mass ratio inspiral are unique sources to probe strong lensing due to their cosmological distances and large signal-to-noise ratios.
If strong lenses of LISA sources are identified, they can be used as precision probes of the source properties and its population, testing General Relativity and measuring cosmological parameters, enabling unique cosmological and astrophysical measurements.
This project explores the rates and detectability of lensed LISA sources.
