Abstract:
Since the first detection in 2015, over 300 gravitational wave events have been observed by the LIGO-Virgo-KAGRA collaboration, revealing the population of stellar-mass black holes and raising new questions about compact binary formation. The 2017 binary neutron star merger marked the beginning of multi-messenger astronomy, providing insights into the origin of heavy elements, neutron star physics, theories of gravity, and cosmology. However, such multi-messenger observations have only been achieved once so far.
To improve this situation, enhancing detector sensitivity and expanding the global network are essential. In particular, upgrades to KAGRA and the addition of LIGO-India will significantly improve sky localization and polarization measurements. In the late 2030s, next-generation observatories such as the Einstein Telescope and Cosmic Explorer will enable observations of compact binary mergers across the entire universe. This talk will highlight the scientific potential of ground-based gravitational wave observatories and the key technologies that will make it possible.
