Abstract

Gravitational waves [1] have opened an entirely new window to the observation of our universe, both on their own, and in the context of multimessenger investigations. The next generation of gravitational wave detectors is in the preparatory stage, including the Einstein Telescope [2], in which Austria intends to participate, and the LISA space telescope. Both will provide unprecedented sensitivity and statistics, with event rates and types of events orders of magnitude beyond the current possibilities. This requires preparations from many angles. 

One is, of course, to fully exploit the provided data. Another one is to envision new avenues for exploring the data. The unprecedented precision will not only allow us to address astrophysical problems that are still open, but may, in fact, also allow us to explore quantum gravity for the very first time observationally. In many theories of quantum gravity, black holes are not structureless [3]; thus, signals of their mergers may be modulated, akin to what happens for neutron stars [4]. 

This symposium will bring together experts to prepare for these new stages in gravitational wave astronomy, discussing both efficient ways to acquire data and novel ways to utilize it, thereby preparing the Austrian community to play a significant role in this groundbreaking new area.
