Abstract

The first space-based gravitational wave observatory, the Laser Interferometer Space Antenna (LISA), will enable us to listen to gravitational waves between 100 μHz and 1 Hz. This ESA-led L-class mission will detect mergers involving ten thousand to ten million solar mass black holes throughout the universe, a million compact galactic binaries involving white dwarfs, neutron stars, and stellar mass black holes and many other gravitational wave signals. LISA will use laser interferometry to measure minuscule changes in the distance between six free falling test masses on board of three spacecrafts which form a 2.5Gm equilateral triangle. I will discuss the science case for LISA, the measurement principle, its technology readiness and the plans towards a launch in 2035.
