Simultaneous constraints on the growth of structure and cosmic expansion from the multipole power spectra of the SDSS DR7 LRG sample

Akira Oka, Shun Saito, Takahiro Nishimichi +2

The anisotropic galaxy clustering on large scales provides us with a unique opportunity to probe into the gravity theory through the redshift-space distortions (RSDs) and the Alcoc…

Simulating the Anisotropic Clustering of Luminous Red Galaxies with Subhalos: A Direct Confrontation with Observation and Cosmological Implications

Takahiro Nishimichi, Akira Oka

We model the apparent clustering anisotropy of Luminous Red Galaxies (LRGs) in the Sloan Digital Sky Survey using subhalos identified in cosmological N-body simulations. We first…

Beyond consistency test of gravity with redshift-space distortions at quasi-linear scales

Atsushi Taruya, Kazuya Koyama, Takashi Hiramatsu +1

Redshift-space distortions (RSD) offer an attractive method to measure the growth of cosmic structure on large scales, and combining with the measurement of the cosmic expansion hi…
