Galaxy-galaxy lensing is a powerful probe to study the properties of dark matter, e.g. density profile, dark matter halo mass e.t.c. Combining clustering, it can also constrain cosmological parameters within standard cosmology. What is more, we can extend its constraining power to non-standard cosmology, testing GR at galactic scale as well as modified gravity.
