LISA Gravitational Reference Sensors
We review state of the art of the gravitational reference sensor (GRS) for the Laser Interferometer Space Antenna (LISA). LISA consists of three identical spacecraft placed at the corners of an equilateral triangle with a 5 million kilometer baseline. In the LISA baseline design, the spacecraft at each corner will have two optical assemblies subtending an angle of 60 degrees. A proof mass (PM) ...
متن کاملLISA: Probing the Universe with Gravitational Waves
Thanks to the many other members and friends of the LISA science community who provided valuable input and suggestions. The New Science of Gravitational Waves Einstein's theory of spacetime and gravity, general relativity, predicts that motions of mass produce propagating vibrations that travel through spacetime at the speed of light. These gravita-tional waves (as the vibrations are called) ar...

متن کاملDetecting an anisotropic gravitational wave background with LISA∗
We address the problem of detecting a stochastic background originated by an anisotropic population of sources, like the galactic binaries, by exploiting the amplitude modulation of the signal as the antenna changes its orientation with respect to fixed stars. This modulation, if observed, could help in discriminating the background generated by galactic binaries from the isotropic gravitationa...
متن کاملAngular Resolution of the LISA Gravitational Wave Detector
We calculate the angular resolution of the planned LISA detector, a space-based laser interferometer for measuring low-frequency gravitational waves from galactic and extragalactic sources. LISA is not a pointed instrument; it is an all-sky monitor with a quadrupolar beam pattern. LISA will measure simultaneously both polarization components of incoming gravitational waves, so the data will con...
