Description
Most of what we know so far about the origin and evolution of the Universe is based on the information carried by electromagnetic radiation received from distant objects or composing the CMB. The recent direct detections of Gravitational Waves (GWs) have opened a new window of observation for phenomena in which gravity, instead of light, is the messenger. A few black hole and neutron star mergers have been reported and a plethora of new events are expected to be detected in the near-to-mid future. Many possible sources, especially related to the physics of the early Universe, produce (stochastic backgrounds of) GWs with a characteristic frequency much larger than the LIGO frequency range. The detection of high frequency GWs (HFGWs) is however very challenging, and only a few proposals have been made so far.

The goal of this workshop is an open-minded discussion on the experimental and theoretical prospects of HFGWs. What are the possible sources and how well are they theoretically understood? What are the challenges faced in experimental setups and what are possible ideas to go beyond current technology? What can we learn about our Universe within the expected sensitivity of these proposals in the next decade? Our goal is to tackle these open questions by gathering a selected sample of people who are interested in these questions both from the theoretical and the experimental points of view. A few dedicated talks aim at introducing the key aspects and questions and bridging the gap between the different communities, while leaving ample time for discussions.
