We lack a predictive model for how a star of a given mass explodes and what kind of remnant it leaves behind (i.e. the initial-final mass relation, IFMR). Astrometric gravitational lensing offers a new way to find and weigh compact objects and place the first constraints on the IFMR, compact object multiplicity, and kick velocities.
