Caltech/JPL Association for Gravitational-Wave Research Seminar

The DECi-hertz Interferometer Gravitational wave Observatory (DECIGO) is the future Japanese space gravitational-wave antenna. The goal of DECIGO is to detect gravitational waves from various kinds of sources, such as the beginning of the universe, mainly between 0.1 Hz and 10 Hz, and thus to open a new window of observation for gravitational-wave astronomy. DECIGO will consist of three drag-free spacecraft, 1000 km apart from each other, whose relative displacements are measured by a Fabry-Perot Michelson interferometer. We plan to launch DECIGO Pathfinder (DPF) first to demonstrate the technologies required to realize DECIGO. DPF was selected as one of the five important mission candidates for the small-science satellite series run by JAXA/ISAS.
