A Closure Theory for Non-linear Evolution of Cosmological Power Spectra
Atsushi Taruya, Takashi Hiramatsu
We apply a non-linear statistical method in turbulence to the cosmological perturbation theory and derive a closed set of evolution equations for matter power spectra. The resultan…
Measuring a Parity Violation Signature in the Early Universe via Ground-based Laser Interferometers
Naoki Seto, Atsushi Taruya
We show that pairs of widely separated interferometers are advantageous for measuring the Stokes parameter V of a stochastic background of gravitational waves. This parameter chara…
Probing polarization states of primordial gravitational waves with CMB anisotropies
Shun Saito, Kiyotomo Ichiki, Atsushi Taruya
We discuss the polarization signature of primordial gravitational waves imprinted in cosmic microwave background (CMB) anisotropies. The high-energy physics motivated by superstrin…
Characteristic Scales of Baryon Acoustic Oscillations from Perturbation Theory: Non-linearity and Redshift-Space Distortion Effects
Takahiro Nishimichi, Hiroshi Ohmuro, Masashi Nakamichi +7
An acoustic oscillation of the primeval photon-baryon fluid around the decoupling time imprints a characteristic scale in the galaxy distribution today, known as the baryon acousti…
Measurement of the Rossiter--McLaughlin Effect in the Transiting Exoplanetary System TrES-1
Norio Narita, Keigo Enya, Bun'ei Sato +9
We report a measurement of the Rossiter--McLaughlin effect in the transiting extrasolar planetary system TrES-1, via simultaneous spectroscopic and photometric observations with th…
