Multitracer technique for galaxy bispectrum - An application to constraints on non-local primordial non-Gaussianities -

Daisuke Yamauchi, Shuichiro Yokoyama, Keitaro Takahashi

We explore the use of galaxy bispectra with multitracer technique as a possible probe of primordial non-Gaussianities. We forecast future constraints on non-linearity parameters, $…

Primordial black hole formation in the matter-dominated phase of the Universe

Tomohiro Harada, Chul-Moon Yoo, Kazunori Kohri +2

We investigate primordial black hole formation in the matter-dominated phase of the Universe, where nonspherical effects in gravitational collapse play a crucial role. This is in c…

Constraining the EoR model parameters with the 21cm bispectrum

Hayato Shimabukuro, Shintaro Yoshiura, Keitaro Takahashi +2

We perform a Fisher analysis to estimate the expected constraints on the Epoch of Reionization (EoR) model parameters (i.e., minimum virial temperature, the ionizing efficiency and…

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…

Ultra slow-roll G-inflation

Shin'ichi Hirano, Tsutomu Kobayashi, Shuichiro Yokoyama

The conventional slow-roll approximation is broken in the so-called "ultra slow-roll" models of inflation, for which the inflaton potential is exactly (or extremely) flat. The inte…

Primordial Black Hole Scenario for the Gravitational-Wave Event GW150914

Misao Sasaki, Teruaki Suyama, Takahiro Tanaka +1

We point out that the gravitational-wave event GW150914 observed by the LIGO detectors can be explained by the coalescence of primordial black holes (PBHs). It is found that the ex…

Cosmology with the Square Kilometre Array by SKA-Japan

Daisuke Yamauchi, Kiyotomo Ichiki, Kazunori Kohri +8

In the past several decades, the standard cosmological model has been established and its parameters have been measured to a high precision, while there are still many of the funda…
