Effect of gravitational redshift on space-based gravitational wave detection with clock comparison

Classical and Quantum Gravity
Abstract With the rapid development of atomic clocks, the potential for gravitational-wave detection through clock comparisons emerges as a viable prospect for the future. Given the profound significance of gravitational redshift and time dilation in such comparisons, assessing its impact on gravitational wave ...

Estimate of magnetic stiffness noise in space-based gravitational wave detection

Classical and Quantum Gravity
Abstract Magnetic noises play a key role in the instrument sensitivity in the low frequency regime, which corresponds to the measurement band of interest for future space-based gravitational wave detection. The magnetic noises can be divided into those that are time variant, but independent of test mass position ...

Design and verification of a piezoelectric-driven locking and handover mechanism for space-based gravitational wave detection

Review of Scientific Instruments
Space inertial sensors, comprising a test mass and its surrounding framework, are pivotal for high-precision gravitational wave detection. The precise locking and handover of the test mass are crucial, particularly during launch and orbital insertion phases.

Phasemeter based on second harmonic signal filter for space-based gravitational wave detection

Chinese Physics B
Abstract The space gravitational wave detection aims to detect gravitational waves in the mHz band in order to study supermassive black hole mergers, galaxy evolution and the structure of the early universe. One of its core payloads is a transponder-type interstellar laser interferometer, designed to measure relative displacement ...

Space-based gravitational wave detection and how LISA Pathfinder successfully paved the way

Nature Physics, 2019
In 2016 and 2017, the LISA Pathfinder mission successfully proved that the technologies for the space-based gravitational wave detector LISA are ready. LISA is now scheduled to launch in the early 2030s, to open a so far unexploited scientific field.
