Path to Kilohertz Gravitational-Wave Astronomy

We are entering an exponentially growing phase of gravitational-wave (GW) astronomy, excitingly represented by the Nobel Prize in Physics last year - only two years after the first detection. The successful multi-messenger detection of binary neutron star merger in last August has triggered increasing interests to probe the neutron star post-merger gravitational radiations, as they will give more decisive and informative description of the post-merger object itself and the GW/electromagnetic emission mechanism. As the post-merger GWs mainly lie in the 1kHz-4kHz band, it becomes necessary and important to think about possible third-generation GW detectors that are primarily sensitive to the high frequency band.  In this workshop, we shall focus on possible science case and detector configuration for kHz high-frequency detectors. We will have several invited talks, while leaving more time for free discussions. We hope this workshop can serve as a seed for much broader discussions in the GW astronomy community, and help promote high frequency detectors as one of the development directions of third-generation GW detectors.
