Imprints of flat space analyticity in de Sitter S-matrix
Jason Kristiano, Ryo Namba, Atsushi Naruko +2
The analytic structure of the flat-space S-matrix provides non-perturbative constraints on low-energy effective field theories based on the properties of high-energy theory. While…
First test of the consistency relation for the large-scale structure using the anisotropic three-point correlation function of BOSS DR12 galaxies (An explanatory video is available at https://youtu.be/Zi36ooLPhss.)
Naonori S. Sugiyama, Daisuke Yamauchi, Tsutomu Kobayashi +6
We present, for the first time, an observational test of the consistency relation for the large-scale structure (LSS) of the Universe through a joint analysis of the anisotropic tw…
Probing the primordial Universe with 21-cm line from cosmic dawn/epoch of reionization
Teppei Minoda, Shohei Saga, Tomo Takahashi +4
In the most distant reaches of the Universe, the 21-cm hyperfine transition in neutral hydrogen provides one of the only available tracers of large-scale structure. A number of ins…
New constraints on cosmological modified gravity theories from anisotropic three-point correlation functions of BOSS DR12 galaxies
Naonori S. Sugiyama, Daisuke Yamauchi, Tsutomu Kobayashi +6
We report a new test of modified gravity theories using the large-scale structure of the Universe. This paper is the first attempt to (1) apply a joint analysis of the anisotropic…
Cosmological gravity probes: connecting recent theoretical developments to forthcoming observations
Shun Arai, Katsuki Aoki, Yuji Chinone +20
Since the discovery of the accelerated expansion of the present Universe, significant theoretical developments have been made in the area of modified gravity. In the meantime, cosm…
Skewness consistency relation in large-scale structure and test of gravity theory
Daisuke Yamauchi, Shoya Ishimaru, Takahiko Matsubara +1
We investigate the skewness of galaxy number density fluctuations as a possible probe to test gravity theories. We find that the specific linear combination of the skewness paramet…
