Anja Feldmeier: The Milky Way Nuclear Star Cluster Beyond 1 pc

Observing the cluster
  • slit-scanning the central cluster with ISAAC
  • foreground removal based on colors
  • included Q-branch H2 lines, stellar CO absorption lines
  • CO -> stellar velocity dispersions
  • flat velocity dispersion profile + fitting profile -> underestimate of BH mass + may affect other galaxies

Questions

  • Q Fred Lo: Method vs external galaxies. Couldn't understand.
  • Q: What is the error on the anisotropy?
  • A: can fit with different anisotropy
  • Q Lu(?): What happens if you include IR7?
  • A: v disp drops towards center. Problem.
  • Q Soo(?): Does model allow stellar rotation?
  • A: ???
