Universal Upper Bound on the Inflationary Energy Scale from the Trans-Planckian Censorship Conjecture
Shuntaro Mizuno, Shinji Mukohyama, Shi Pi +1
We study the constraint on the inflationary energy scale from the recently proposed Trans-Planckian Censorship Conjecture (TCC). We find a universal upper bound on the inflationary…
Primordial Tensor Non-Gaussianity from Massive Gravity
Tomohiro Fujita, Shuntaro Mizuno, Shinji Mukohyama
We calculate tensor bispectrum in a theory of massive tensor gravitons which predicts blue-tilted and largely amplified primordial gravitational waves. We find that a new 3-point i…
Quantum Entanglement in Multi-field Inflation
Nadia Bolis, Tomohiro Fujita, Shuntaro Mizuno +1
We study the emergence of quantum entanglement in multi-field inflation. In this scenario, the perturbations of one field contribute to the observable curvature perturbation, while…
Constraining equilateral-type primordial non-Gaussianities from imaging surveys
Ichihiko Hashimoto, Shuntaro Mizuno, Shuichiro Yokoyama
We investigate expected constraints on equilateral-type primordial non-Gaussianities from future/ongoing imaging surveys, making use of the fact that they enhance the halo/galaxy b…
Halo/Galaxy Bispectrum with Equilateral-type Primordial Trispectrum
Shuntaro Mizuno, Shuichiro Yokoyama
We investigate the effect of equilateral-type primordial trispectrum on the halo/galaxy bispectrum. We consider three types of equilateral primordial trispectra which are generated…
Transients from initial conditions based on Lagrangian perturbation theory in -body simulations II: the effect of the transverse mode
Takayuki Tatekawa
We study the initial conditions for cosmological -body simulations for precision cosmology. In general, Zel'dovich approximation has been applied for the initial conditions of $…
