Dr. Gudrun Wanner

Senior Scientist in Space Interferometry

What are your responsibilities at our institute?

  • Coordinator of the Simulation Working Group within the Space Interferometry Working Group
  • (Co-)Chair of the Stray Light Working Group within the LISA consortium
  • PI in “LEGACY”, a research collaboration between the Max Planck Society and the Chinese Academy of Science

Can you please summarize your research?

Gravitational waves are famous since the first LIGO detection, followed by so many more detections. I am interested in realizing the space gravitational wave detector LISA, a 2.5 Mkm triangular shaped interferometer, whose end points are three satellites. I am specialized on the LISA interferometry and in particular on optical simulations that are needed in order to ensure the excellent noise performance we need for LISA.

Do you have a favourite figure from a paper you co-authored?

from „Sub-Femto-g Free Fall for Space-Based Gravitational Wave Observatories: LISA Pathfinder Results“ (PRL 116, 231101 (2016))

This graphic from Sub-Femto-g Free Fall for Space-Based Gravitational Wave Observatories: LISA Pathfinder Results shows the noise curve of LISA Pathfinder in 2016, showing the excellent performance of the LISA Pathfinder mission in the early mission phase. The bump labeled with “pick-up of spacecraft motion” is a key element of my research. It shows the so called “tilt-to-length cross coupling”, which is unintended pick-up of angular jitter and lateral motion of the spacecraft into the interferometric readout.
