Redshift Evolution of the Intrinsic Alignments of Early-Type Galaxies and Subhalos in the Horizon Run 5 Simulation
Sanghyeon Han, Motonari Tonegawa, Ho Seong Hwang +8
We investigate the redshift evolution of intrinsic alignments of the shapes of galaxies and subhalos with the large-scale structures of the universe using the cosmological hydrodyn…
Topological approach to void finding applied to the SDSS galaxy map
Manu Aggarwal, Motonari Tonegawa, Stephen Appleby +2
The structure of the low redshift Universe is dominated by a multi-scale void distribution delineated by filaments and walls of galaxies. The characteristics of voids; such as morp…
Intrinsic Alignments and Spin Correlations of [OII] Emitters at and from HSC Narrow-band Survey
Motonari Tonegawa, Teppei Okumura, Masao Hayashi
Galaxies are known to be aligned toward specific directions within the large-scale structure. Such alignment signals become important for controlling the systematics of weak lensin…
The effects of non-linearity on the growth rate constraint from velocity correlation functions
Motonari Tonegawa, Stephen Appleby, Changbom Park +2
The two-point statistics of the cosmic velocity field, measured from galaxy peculiar velocity (PV) surveys, can be used as a dynamical probe to constrain the growth rate of large-s…
Cosmological Parameter Constraints from the SDSS Density and Momentum Power Spectra
Stephen Appleby, Motonari Tonegawa, Changbom Park +3
We extract the galaxy density and momentum power spectra from a subset of early-type galaxies in the SDSS DR7 main galaxy catalog. Using galaxy distance information inferred from t…
First Evidence of Intrinsic Alignments of Red Galaxies at : Cross-correlation between CFHTLenS and FastSound Samples
Motonari Tonegawa, Teppei Okumura
We report the first evidence for intrinsic alignment (IA) of red galaxies at . We measure the gravitational shear-intrinsic ellipticity (GI) cross-correlation function at $z\s…
Cosmological Parameter Estimation from the Two-Dimensional Genus Topology -- Measuring the Expansion History using the Genus Amplitude as a Standard Ruler
Stephen Appleby, Changbom Park, Sungwook E. Hong +3
We measure the genus of the galaxy distribution in two-dimensional slices of the SDSS-III BOSS catalog to constrain the cosmological parameters governing the expansion history of t…
Cosmological Information from the Small-scale Redshift Space Distortions
Motonari Tonegawa, Changbom Park, Yi Zheng +4
The redshift-space distortion (RSD) in the observed distribution of galaxies is known as a powerful probe of cosmology. Observations of large-scale RSD have given tight constraints…
Alcock-Paczynski Test with the Evolution of Redshift-Space Galaxy Clustering Anisotropy
Hyunbae Park, Changbom Park, Cristiano G. Sabiu +5
We develop an improved Alcock-Paczynski (AP) test method that uses the redshift-space two-point correlation function (2pCF) of galaxies. Cosmological constraints can be obtained by…
The Subaru FMOS galaxy redshift survey (FastSound). V. Intrinsic alignments of emission line galaxies at
Motonari Tonegawa, Teppei Okumura, Tomonori Totani +3
Intrinsic alignments (IA), the coherent alignment of intrinsic galaxy orientations, can be a source of a systematic error of weak lensing surveys. The redshift evolution of IA also…
The Subaru FMOS galaxy redshift survey (FastSound). IV. New constraint on gravity theory from redshift space distortions at
Teppei Okumura, Chiaki Hikage, Tomonori Totani +22
We measure the redshift-space correlation function from a spectroscopic sample of 2783 emission line galaxies from the FastSound survey. The survey, which uses the Subaru Telescope…
