Multi-band observation of lensed gravitational waves as a probe of small-mass dark matter halos
Katsuya T. Abe, Shun Arai, Ryoto Inui +3
The gravitational lensing effect of gravitational waves (GWs) has been extensively discussed as a probe of small-mass dark matter halos, which can provide missing information about…
Primordial black holes and induced gravitational waves from logarithmic non-Gaussianity
Ryoto Inui, Cristian Joana, Hayato Motohashi +3
We investigate the formation of primordial black hole (PBH) based on numerical relativity simulations and peak theory as well as the corresponding scalar induced gravitational wave…
The LISA forecast on a smooth crossover beyond the Standard Model through the scalar-induced gravitational waves
Albert EscrivÃ, Ryoto Inui, Yuichiro Tada +1
Supposing the Laser Interferometer Space Antenna (LISA) gravitational wave (GW) detector, we exhibit the detectability of a hypothetical smooth crossover in the early universe beyo…
Constant roll and non-Gaussian tail in light of logarithmic duality
Ryoto Inui, Hayato Motohashi, Shi Pi +2
The curvature perturbation in a model of constant-roll (CR) inflation is interpreted in view of the logarithmic duality discovered in Ref. [1] according to the formalism. We…
