A universal connection between lens density profiles and low-frequency wave optics in gravitational-wave lensing
So Tanaka, Teruaki Suyama
We investigate the low-frequency behavior of the amplification factor in gravitational lensing and explore how it encodes information about the density profile of the lensing objec…

Towards model-independent identification of lensed gravitational waves using Kramers-Kronig relation
So Tanaka, Gopalkrishna Prabhu, Shasvath J. Kapadia +1
Observations of microlensed gravitational waves (GWs) emanated by compact binary coalescences (CBCs) are essential for studying the mass density distribution in the universe, inclu…

Novel Quantity for Probing Matter Perturbations Below the Fresnel Scale in Gravitational Lensing of Gravitational Waves
So Tanaka, Teruaki Suyama
Gravitational lensing of gravitational waves provides a powerful probe of the mass density distribution in the universe. Wave optics effects, such as diffraction, make the lensing…
