Signatures of Dark Matter halos in LISA via Stochastic Diffraction
Han Gil Choi, Juan Urrutia, Miguel Zumalacárregui
The paper investigates how wave‑optics lensing by many low‑mass dark‑matter halos along the line of sight can produce stochastic diffraction signatures in LISA gravitational‑wave s…

Can Horndeski Genesis be Nonpathological?
Han Gil Choi, Pavel Petrov, Masahide Yamaguchi
We present a minimal setup within the framework of Horndeski gravity that can describe a nonpathological Genesis scenario. Our setup allows for a fully stable transition to the kin…

Probing small-scale power spectrum with gravitational-wave diffractive lensing
Sungjung Kim, Han Gil Choi, Sunghoon Jung
We develop a novel way to probe subgalactic-scale matter distribution with diffractive lensing on gravitational waves. Five-year observations from Einstein Telescope and DECIGO are…
