Probing soft signals of gravitational-wave memory with space-based interferometers
The paper investigates detecting gravitational-wave displacement memory using future space-based interferometers like LISA and Taiji. It analyzes three types of soft waveforms—displacement, velocity, and integrated-displacement memory—and shows that these signals are detectable at high signal-to-noise ratios for specific amplitudes. This suggests they are promising targets for future space missions.
