Space Gravitational-Wave Detection
March 27-29, 2019
Room 341, Area C, Faculty of Science Bldg.1, the University of Tokyo
Direct detection of gravitational waves by LIGO and Virgo opened a new era of gravitational-wave astronomy and astrophysics.
The ground-based laser interferometers are sensitive to 100 Hz band and have successfully detected signals from binary black hole coalescence
as well as binary neutron star coalescence, which was also observed by vast wavelength ranges of electromagnetic waves thereby initiating the multi-messenger astronomy.
This remarkable achievement is certainly not the whole story of gravitational-wave science,
as those with different wavelengths will convey us different information of the current and early Universe.
But different techniques are required to observe these gravitational waves.
The aim of this workshop is to discuss future of the multi-frequency gravitational waves
with a particular emphasis on detection of low frequency gravitational waves by the detectors launched in space.
In Europe, LISA path finder was extremely successful and its full version will be launched in 2030s.
Japanese groups are also joining this project.
In China, TianQin project has been rapidly in progress.
Finally, DECIGO, originally proposed in 2001, is recognized as the next key project after KAGRA in the Japanese gravitational-wave research community,
starting with its initial version B-DECIGO with the hope to proceed to its ultimate version eventually, which would be able to measure when the Big Bang happened.
Other means of detection of ultra-low frequency gravitational waves using B-mode polarization of the cosmic microwave background radiation
and pulsar timing will also be discussed.

The workshop banquet will be held on March 28th at Lever son Verre Tokyo
The fee is 5000 JPY per person.
