Abstract (AI)
Following the selection of The Gravitational Universe by ESA, and the successful flight of LISA Pathfinder, the LISA Consortium now proposes a 4 year mission in response to ESA's call for missions for L3. The observatory will be based on three arms with six active laser links, between three identical spacecraft in a triangular formation separated by 2.5 million km. LISA is an all-sky monitor and will offer a wide view of a dynamic cosmos using Gravitational Waves as new and unique messengers to unveil The Gravitational Universe. It provides the closest ever view of the infant Universe at TeV energy scales, has known sources in the form of verification binaries in the Milky Way, and can probe the entire Universe, from its smallest scales near the horizons of black holes, all the way to cosmological scales. The LISA mission will scan the entire sky as it follows behind the Earth in its orbit, obtaining both polarisations of the Gravitational Waves simultaneously, and will measure source parameters with astrophysically relevant sensitivity in a band from below $10^{-4}\,$Hz to above $10^{-1}\,$Hz.
Key Findings
1
LISA will observe known verification binaries in the Milky Way and probe phenomena ranging from black-hole horizons to cosmological scales.
2
LISA will operate as an all-sky gravitational-wave observatory, simultaneously measuring both gravitational-wave polarizations as it orbits behind Earth.
3
The four-year mission aims to investigate the infant Universe at TeV energy scales using gravitational waves as unique messengers.
4
The mission will achieve astrophysically relevant source-parameter sensitivity across frequencies from below 10^-4 Hz to above 10^-1 Hz.
5
The proposed LISA mission uses three spacecraft in a triangular formation, separated by 2.5 million km and connected by six active laser links.
