Challenge of High-Frequency Gravitational Waves Detection — •Gudrid Moortgat-Pick1,2, Tom Krokotsch1, Michel Paulsen1, Alexander Schneider1, Marc Wenskat2, Krisztian Peters2, Andreas Ringwald2, and Giovanni Marconato1 — 1University of Hamburg — 2DESY
High frequency gravitational waves (GWs) remain unexplored messengers of new physics. Proposed sources in the MHz - GHz band include primordial black hole mergers, black hole superradiance and several stochastic backgrounds.Our collaboration is working on tapping into this source by employing superconducting microwave cavities for high precision measurements of harmonic displacements.
The talk give an actual status report on the experimental as well as the theoretical new developments including the measurements as well as background considerations.
