Space gravitational wave detection: Progress and outlook

SCIENTIA SINICA Physica, Mechanica & Astronomica
Space-based gravitational wave detection is based on the astrodynamical equations derived from gravitational theory to detect changes in distance between spacecraft/celestial bodies and/or their state changes caused by gravitational waves. The fundamental method involves using electromagnetic waves (including radio waves, microwaves, light waves, X ...

The Reliability Modeling and Evaluation of a Cusped Field Thruster When Undertaking a Gravitational Wave Detection Mission

Aerospace
The propulsion system, particularly electric propulsion, holds immense significance in the context of gravitational wave detection missions. One of the key factors of a deep space exploration mission is the lifetime of the electric propulsion.

Parameter-space correlations of the optimal statistic for continuous gravitational-wave detection

, 2008
The phase parameters of matched-filtering searches for continuous gravitational-wave signals are sky position, frequency and frequency time-derivatives. The space of these parameters features strong global correlations in the optimal detection statistic.
