Small-scale shear: Peeling off diffuse subhalos with gravitational waves
Han Gil Choi, Chanung Park, Sunghoon Jung
Subhalos at subgalactic scales ( or ) are pristine test beds of dark matter (DM). However, they are too small, diffuse and d…
GRB lensing parallax: Closing primordial black hole dark matter mass window
Sunghoon Jung, TaeHun Kim
The primordial black hole (PBH) comprising full dark matter (DM) abundance is currently allowed if its mass lies between .…
Probing Cosmic Strings with Gravitational-Wave Fringe
Sunghoon Jung, TaeHun Kim
Cosmic strings are important remnants of early-Universe phase transitions. We show that they can be probed by Gravitational Waves (GWs) from compact binary mergers. If such chirpin…
Gravitational-Wave Fringes at LIGO: Detecting Compact Dark Matter by Gravitational Lensing
Sunghoon Jung, Chang Sub Shin
Utilizing gravitational-wave (GW) lensing opens a new way to understand the small-scale structure of the universe. We show that, in spite of its coarse angular resolution and short…
