| Abstract: |
We present the first measurement of the three-dimensional density profile of the inner 0.6 pc of the Milky Way's nuclear star cluster (NSC). This work is the first to use astrometrically-measured, projected accelerations of late-type stars to infer their line-of-sight distances. Using Bayesian statistics, we have investigated what set of density profile parameters match all of our data best. Our preliminary analysis shows that the most likely 3D density profile is consistent with having no cusp. |
