Gravitational wave has become a new window to explore our universe. Among many events detected so far, GW170817 was the first binary neutron star gravitational wave event joint with electromagnetic observations, which revolutionized our understanding of neutron star physics and the origin of kilonova. However, due to a limited detector sensitivity at the high frequency around kHz, we did not observe the most energetic part of this event---the catastrophic merger of the two neutron stars. In this talk, I will present the latest developments in the design study of kHz detectors for observing the merger signals, which include the upgrade plans for existing facilities and designs of the next-generation gravitational-wave observatory.


Haixing Miao obtained his PhD degree from the University of Western Australia in 2010. Afterwards, he went to Caltech as a postdoc for three years. From 2014 to 2021, he was a faculty member at the University of Birmingham. Since October last year, he joined the Department of Physics at Tsinghua University and is now a senior group member of the LIGO Scientific Collaboration. His research focuses on gravitational-wave instrumentation science and quantum measurements.
