Detecting the gravitational wave memory effect with TianQin

The gravitational wave memory effect is a prediction of general relativity. presence in signals not only provides the chance to test an important aspect relativity, but also represents potentially non-negligible contribution waveform for certain events. In this paper, we study prospect detecting directly with planned space-based detector -- TianQin. We find that during its 5 years operation, could be detected by TianQin, about $0.5\sim2.0$ may contain displacement signal-to-noise ratios (SNRs) greater than 3. This suggests TianQin detect low fully negligible. contrast, spin which parameter space, expected significant modeling.
