Description
The 21st century marks the beginning of the age of multimessenger astronomy. After decades of waiting the ground-based gravitational wave detectors of the Laser Interferometer Gravitational-Wave Observatory allowed us to directly detect gravitational waves, and the expanding network of neutrino detectors provided us with access to a broad range of previously undetected neutrino sources. Thus for the first time we have all four messengers, photons, gravitational waves, neutrinos, and cosmic rays, at our disposal to investigate the fundamental laws of physics. Unfortunately, the interpretation of the collected data still strongly relies on fitting them to the output of analytical and numerical models. However, if we want to extract all information transported by the different messenger signals, we have to develop a much more systematic approach for multimessenger observations and, in particular, the analysis of the collected data. The goal of this talk is now to present such an approach: The Maxwell-Einstein-Pauli Observatory. When realised the Maxwell-Einstein-Pauli Observatory will use data assimilation techniques to combine data with theoretical models, which has the potential to provide us with much more precise results than traditional fitting techniques. In my talk I will now first outline the basic structure of the Maxwell-Einstein-Pauli Observatory. Then I will provide a brief overview over different data assimilation techniques and how they help us to combine observational data with theoretical models. I will discuss potential science targets and how we can apply the method to probing gravity in the strong field regime in the close vicinity of black holes.
