High-precision infrared astrometry is a powerful tool for the study of resolved stellar populations throughout our Galaxy. We highlight two particular science cases that require precise infrared astrometry: (1) measuring the initial mass function in massive young clusters throughout the MilkyWay and (2) finding isolated black holes that photometrically and astrometrically lens background bulge stars. Using astrometric results from these science cases, we perform a comparative analysis of the...[Show more]
