Probing the spin of compact objects with gravitational microlensing of gravitational waves
Gopalkrishna Prabhu, Uddeepta Deka, Sumanta Chakraborty +1
Propagating gravitational waves (GWs) can encounter a massive object (lens) whose gravitational radius is comparable to the wavelength of the GWs (wave-optics regime). The resultin…

Probing charge of compact objects with gravitational microlensing of gravitational waves
Uddeepta Deka, Sumanta Chakraborty, Shasvath J. Kapadia +2
Gravitational microlensing of gravitational waves (GWs) opens up the exciting possibility of studying the spacetime geometry around the lens. In this work, we investigate the prosp…
