    talk

    William Joseph Weber for the LISA Consortium

    LISA, the Laser Interferometer Space Antenna, is in preparation to become the ESA Cosmic Vision L3 mission, an orbiting observatory for gravitational waves in the milliHz band with a target launch in 2035. We present here an overview of the LISA measurement concept and baseline hardware, from the heritage of the single-spacecraft LISA Pathfinder...

  2. 114. Space GW Antennae: DECIGO/B-DECIGO

    Space missions
    talk

    DECIGO is a future gravitational wave antenna for direct observation of primordial gravitational waves from the early universe. It will be formed by three spacecraft separated by 1,000km from each other. B-DECIGO is its precursor mission with 1/10 scale. It is still very sensitive at 0.1Hz frequency band to observe compact binaries, intermediate-mass BBHs, and GW foregrounds. In this...

    talk

    The TianQin project was initiated in 2014. The goal is to launch the space-based gravitational-wave observatory around 2035 and to detect GWs in the frequency range 10-4~1 Hz. TianQin consists of three satellites on nearly identical geocentric orbits with radii of the order 105 km, forming a normal triangle constellation. In order to achieve the scientific goals, the nongravitational...

  4. 1. Lunar Gravitational-Wave Antenna

    Space missions
    talk

    Gravitational waves excite quadrupolar vibrations of elastic bodies. Monitoring these vibrations was one of the first concepts proposed for the detection of gravitational waves by Joseph Weber. At laboratory scale, these experiments became known as resonant-bar detectors, which form an important part of the history of GW detection. Due to the dimensions of these bars, the targeted signal...

  5. 160. Time-delay interferometry for LISA

    talk

    Olaf Hartwig for the LISA Consortium

    The Laser Interferometer Space Antenna (LISA) is a constellation of 3
    spacecraft orbiting the sun. They form an almost equilateral triangle with arm lengths of 2.5 million kilometers. These arms can differ in length by up to 25000km, such that a traditional Michelson-like interferometer configuration does not reduce laser noise effectively. Thus, LISA...

  6. 40. Enhanced noise suppression for LISA by combining cavity and arm locking control systems

    Space missions
    talk

    The Laser Interferometer Space Antenna (LISA) mission is a space-based gravitational wave detector, that consists of three spacecrafts in a triangular formation with 2.5-million-kilometer sides. The displacement sensitivity goal is approximately 10 pm/√Hz for each arm-link to detect gravitational waves in the frequency band, 100 $\mu$Hz to 1 Hz.
    The proposed research introduces a novel...
