Since October 2013 I am a postdoctoral researcher at Case Western Reserve University in Cleveland, Ohio, working with Stacy McGaugh. I have finished my PhD studies at the Argelander Institute for Astronomy (AIfA) in Bonn, supervised by Prof. Pavel Kroupa, in August 2013.

My research centers on the phase-space distribution of dwarf galaxies in the Local Group, in particular the satellites of the Milky Way. I am using them to test cosmological models and investigate whether a they could have been formed as tidal dwarf galaxies in a past galaxy collision, which would explain the vast polar structure (VPOS) around our Galaxy. I discovered that this VPOS consists not only of dwarf galaxies, but also of globular clusters and streams of disrupted systems orbiting our Galaxy. My research indicates that this tidal scenario is indeed viable, which is further supported by the discovery of additional planar satellite distributions in the Local Group.

Research Interests

  • Satellite galaxies of the Milky Way and Andromeda galaxy, their phase-space distribution, possible scenarios for their origin and its implications for our understanding of cosmology.

  • Tidal Dwarf Galaxies (TDGs), their creation, evolution and properties.

  • Galaxy-interactions and -collisions.

  • Numerical calculations as bridge between theory and observation.

  • Furthermore interested in the Philosophy of Science, especially the Scientific Method and Scientific Realism, as well as public outreach in astronomy.

Jobs

I was teaching assistant for numerous lectures in astrophysics (Numerical Methods in Physics, PD Dr. H. Baumgardt; Astrophysics of Galaxies, Prof. P. Kroupa;  Stars and Stellar Evolution, Prof. N. Langer) and most recently was tutor for the advanced lab course Photometry of Star Clusters at the 50cm-telescope of the AIfA. Previously I worked for the Max-Planck Institute for Radio-Astronomy (MPIfR), giving popular science talks in the visitor pavilion at the 100-meter radio telescope in Effelsberg, helped with the presentation of the AIfA in the science-night in Bonn and the MPIfR in the astronomy tent on the Münsterplatz in the International Year of Astronomy 2009. I was member of the Local Organizing Committee (LOC) of the conferences The Milky Way Halo – Stars and Gas (2007) and Tidal Dwarf Galaxies Bonn (2009), where my task including planning and preparation of the meetings, supporting the guest and doing press relations and (photographic) documentation.
