LISA interferometry
Abstract
The Laser Interferometer Space Antenna (LISA) is a joint NASA/ESA space mission aimed to detect gravitational waves in the 3×10 -5 to 1Hz frequency range. Expected sources for LISA include super massive black hole mergers (SMBH), galactic neutron star and white dwarf binaries, and extreme mass ratio inspirals (EMRI). The three LISA spacecraft will travel in a heliocentric orbit trailing or leading earth by about 20°. The distance between the spacecraft will be about 5 million km or 16s light travel time. Laser interferometry will measure the distance with pm/√Hz accuracy. This report focuses on the technology for LISA interferometry.
