LISA-Detecting and Observing Gravitational Waves

摘要

The primary objective of the LISA (Laser Interferometer Space Antenna) mission is the detection and observation of gravitational Waves from massive black holes and galactic binaries down to a Gravitational wave strain sensitivity of 10~-23 in the frequency range 10~-4-10~-1 Hz (Fig. 1). This low-frequency range is inaccessible to ground-based interferometers because of the unshieldable background of local gravitational noise.
