Unveiling Gravity with Void-Galaxy Cross-Correlation Multipoles
Yue Nan
Cosmic voids provide low-density environments where the scalar fifth force predicted by modified gravity can be weakly screened. We present a semi-analytical calculation of…
On the equivalence between galaxy angular correlation function and power spectrum in constraining primordial non-Gaussianity
Ryo Terasawa, Yue Nan, Masahiro Takada
We investigate the angular power spectrum ( and angular correlation function () of galaxy number density field in the presence of the local-type primordial non-Gauss…
Large-scale structure with superhorizon isocurvature dark energy
Koki Yamashita, Yue Nan, Yuuki Sugiyama +1
The standard cosmological model assumes a homogeneous and isotropic universe as the background spacetime on large scales called the cosmological principle. However, some observatio…
Dark energy model with very large-scale inhomogeneity
Yue Nan, Kazuhiro Yamamoto
We consider a dynamical model for dark energy based on an ultralight mass scalar field with very large-scale inhomogeneities. This model may cause observable impacts on the anisotr…
Entanglement of the Vacuum between Left, Right, Future, and Past: Dirac spinor in Rindler spaces and Kasner spaces
Kazushige Ueda, Atsushi Higuchi, Kazuhiro Yamamoto +2
We study the relations of the positive frequency mode functions of Dirac field in 4-dimensional Minkowski spacetime covered with Rindler and Kasner coordinates, and describe the ex…
Large-scale inhomogeneity of dark energy produced in the ancestor vacuum
Yue Nan, Kazuhiro Yamamoto, Hajime Aoki +2
We investigate large-scale inhomogeneity of dark energy in the bubble nucleation scenario of the universe. In this scenario, the present universe was created by a bubble nucleation…
Gravitational redshift in the void-galaxy cross-correlation function in redshift space
Yue Nan, Kazuhiro Yamamoto
We construct an analytic model for the void-galaxy cross-correlation function that enables theoretical predictions of the dipole signal produced dominantly by the gravitational red…
Higher multipoles of the galaxy bispectrum in redshift space
Yue Nan, Kazuhiro Yamamoto, Chiaki Hikage
As a generalization of our previous work [Phys. Rev. D 95 043528 (2017)], in which an analytic model for the galaxy bispectrum in redshift space was developed on the basis of the h…
An analytic halo approach to the bispectrum of galaxies in redshift space
Kazuhiro Yamamoto, Yue Nan, Chiaki Hikage
We present an analytic formula for the galaxy bispectrum in redshift space on the basis of the halo approach description with the halo occupation distribution of central galaxies a…
