3G-GWD: Gravitationswellenteleskope der dritten Generation
Since their discovery less than 10 years ago, gravitational waves opened a completely new window into our universe. Major breakthroughs were achieved from the observation of approximately one hundred mergers of binary systems, mostly black holes. The current observatories LIGO and VIRGO slowly increased their sensitivity towards their ultimate goals. KAGRA joined observation run three as a new member of the second generation. In parallel the communities are preparing for a major upgrade into the third generation with the ground-based observatories of the Einstein-Telescope and the Cosmic Explorer. Major technological challenges are still ahead of us. The German community, led by the Albert Einstein Institute, provided key technologies for the first and second generations. With a coordinated national effort we want to contribute in the same way to the third generation.
In the sub-project led by Céline Hadziioannou, we aim to characterize seismic noise using Machine Learning. Thereby, our approach focuses on the development of a method to predict the wave fields (transfer function) between two seismic stations. The outcomes of this wave field prediction will specifically aid in characterizing the interference caused by seismic and atmospheric noise on gravitational wave detectors, helping to reduce such interference in a targeted manner.
