The wave nature of continuous gravitational waves from microlensing

Understand

Gravitational wave predicted by General Relativity is the transverse wave of spatial strain.

• Several gravitational waveform signals from binary black holes and from a binary neutron star system accompanied by electromagnetic counterparts have been recorded by advanced LIGO and advanced Virgo.
• In analogy to light, the spatial fringes of diffraction and interference should also exist as the important features of gravitational waves.
• We propose that observational detection of such fringes could be achieved through gravitational lensing of continuous gravitational waves.
