Probing the boundary between star clusters and dwarf galaxies: a MUSE view on the dynamics of Crater/Laevens I
We present MUSE observations of the debated ultra faint stellar system Crater. We spectroscopically confirm 26 member stars of this system via radial velocity measurements. We derive the systematic instrumental velocity uncertainty of MUSE spectra to be 2.27$\rm \,km\,s^{-1}$. This new dataset incre...
