Quintessence with tachyonic resonance and late-time cosmic-microwave-background and gravitational-wave signals
Shun Yoshioka, Kiyotomo Ichiki, Yuichiro Tada +1
Combinations of recent cosmological observations, including Dark Energy Spectroscopic Instrument (DESI), show hints of a dynamical nature for dark energy. While the data suggest th…
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…
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…
Quintessential interpretation of the evolving dark energy in light of DESI
Yuichiro Tada, Takahiro Terada
The recent result of Dark Energy Spectroscopic Instrument (DESI) in combination with other cosmological data shows evidence of the evolving dark energy parameterized by CDM…
