About me

I am an astronomer, currently I work on my PhD thesis at ESO in Garching.
My primary research interests are the formation and evolution of nuclear star clusters. I study the assembly history of the Milky Way nuclear star cluster.


  • K-band spectroscopy
  • IFU and longslit spectroscopy
  • Longslit drift scan observations
  • Stellar kinematics
  • Dynamical modelling
  • Stellar populations

My research

Nuclear star clusters are common objects in nearby galaxies. It is not fully understood how nuclear clusters form: By the infall of massive star clusters, or by gas accretion and in-situ star formation.

Because the Milky Way nuclear star cluster is at a distance of only 8 kpc, we can spatially resolve its stellar populations and kinematics much better than in external galaxies. This makes the Milky Way nuclear star cluster a reference object for understanding the structure and assembly history of all nuclear star clusters.

I study the stellar kinematics of the Milky Way nuclear star cluster in integrated light towards the half-light radius (4.2pc). I run axisymmetric Jeans models and triaxial Schwarzschild models to understand the large-scale kinematics of the Milky Way nuclear star cluster.

With near-infrared K-band spectroscopy of single resolved stars obtained with KMOS (VLT), I study the star formation history and metallicity distribution of the Milky Way nuclear star cluster. The data extend to a larger spatial scale than previous stellar populations studies of the Galactic centre.
