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…
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 c…
Gravitational waves from graviton Bremsstrahlung with kination phase
Ryoto Inui, Yusuke Mikura, Shuichiro Yokoyama
Gravitational waves (GWs) from gravitational three-body decay (graviton Bremsstrahlung process) can leave an indelible signal at ultrahigh frequencies. We focus on a scenario where…
The LISA forecast on a smooth crossover beyond the Standard Model through the scalar-induced gravitational waves
Albert Escrivà, 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…
Prospects of detection of subsolar mass primordial black hole and white dwarf binary mergers
Takahiro S. Yamamoto, Ryoto Inui, Yuichiro Tada +1
The subsolar mass primordial black hole (PBH) attracts attention as robust evidence of its primordial origin against the astrophysical black hole. Not only with themselves, PBHs ca…
Primordial black holes and gravitational waves induced by exponential-tailed perturbations
Katsuya T. Abe, Ryoto Inui, Yuichiro Tada +1
Primordial black holes (PBHs) whose masses are in have been extensively studied as a candidate of whole dark matter (DM). One of the probe…
