Signatures of $10 - 1 0^{4} M_{⊙}$ Dark Matter halos in LISA via Stochastic Diffraction

Han Gil Choi, Juan Urrutia, Miguel Zumalacárregui

Cold Dark Matter predicts a population of low-mass halos which are sensitive to its fundamental nature and the primordial power spectrum, yet remain undetected. Although elusive, t…

Coexistence Test of Primordial Black Holes and Particle Dark Matter from Diffractive Lensing

Han Gil Choi, Sunghoon Jung, Philip Lu +1

If dark matter (DM) consists of primordial black holes (PBHs) and particles simultaneously, PBHs are generically embedded within particle DM halos. Such ``dressed PBHs'' (dPBHs) ar…

Small-scale shear: Peeling off diffuse subhalos with gravitational waves

Han Gil Choi, Chanung Park, Sunghoon Jung

Subhalos at subgalactic scales ( $M ≲ 1 0^{7} M_{⊙}$ or $k ≳ 1 0^{3} Mpc^{- 1}$ ) are pristine test beds of dark matter (DM). However, they are too small, diffuse and d…
