Gravitational wave detectors - current and future challenges — •Michèle Heurs — Leibniz Universität Hannover

Since the first direct detection in 2015, gravitational wave signals have been enriching the field of multi-messenger astronomy with insights into formerly ``invisible'' regimes of the universe. Despite their mind-boggling sensitivities, the current (second) generation of ground-based gravitational wave detectors are limited by various noise sources in their detection band, in particular quantum noise, thermal noise, and seismic noise. Next-generation detectors (e.g. Einstein Telescope, Cosmic Explorer) aim for sensitivities one or two orders of magnitude better even, making innovative techniques for noise reduction or mitigation a requirement. This talk will present challenges and technical developments on the road to ever-higher gravitational wave event detection rates.
