Interferometry in Space
Our department plays the leading role in the development of the space-based gravitational-wave detector LISA (Laser Interferometer Space Antenna). The department also is a major player in the LISA Pathfinder mission, which successfully tested key technologies for LISA from 2015 until 2017. LISA technology also flies onboard the GRACE Follow-On mission, which will observe climate change trough changes in the Earth's gravitational field.
LISA (Laser Interferometer Space Antenna), a space-based detector with million-kilometer long arms will detect low-frequency gravitational waves that cannot be measured by ground based gravitational wave detectors.
GRACE Follow-On observes critical indicators of climate change through changes in Earth's gravitational field using LISA technologly. The mission uses a laser interferometer between two satellites with nanometre-level accuracy.
LISA Pathfinder was the test mission of the European Space Agency ESA for LISA, the first gravitational wave observatory in space. LISA Pathfinder successfully demonstrated central LISA technologies.
AEI is the largest laboratory worldwide for LISA interferometry. We cover the widest range of technologies while keeping close contact to all other participating groups.
LISA Technology Package Data Analysis
LTPDA is a freely available MATLAB-based toolbox which we are developing for LISA Pathfinder data analysis. It is highly useful for other data analysis applications as well.
