2022-10-27 Press Release

An international research group including Yongjia Huang (Student Trainee, iTHEMS) and Shigehiro Nagataki (Deputy Program Director, iTHEMS) has performed numerical simulations based on general relativity for the merger of binary neutron stars and shown that the waveform of gravitational waves emitted after the merger provides detailed readings of the properties of ultra dense matter with a density of over 1 trillion kg per cm3. This research result is expected to contribute to the clarification of the internal structure of neutron stars and the properties of ultra-dense matter in gravitational wave astronomy.
