Gravitational-Wave Memory

(GW Memory, Memory Burst)
(a gravitational wave that does not return)

Gravitational-Wave Memory (GW Memory or Memory Burst) is the phenomena of a Gravitational Wave (GW) after which things "don't return", e.g., the displacement of test masses by the passing of the wave persists. A gravitational wave might have this effect, or might return things somewhat to as before but not completely. Such a memory effect can be linear or nonlinear.

Some detectors are more likely to "see" the non-memory effects of gravitational waves.
