Polarization analysis of gravitational-wave backgrounds from the correlation signals of ground-based interferometers: measuring a circular-polarization mode
Naoki Seto, Atsushi Taruya
The Stokes V parameter characterizes asymmetry of amplitudes between right- and left-handed waves, and non-vanishing value of the V parameter yields a circularly polarized signal.…

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…

The effect of bias and redshift distortions on a geometric test for the cosmological constant
Kazuhiro Yamamoto, Hiroaki Nishioka, Atsushi Taruya
We revisit the feasibility of a cosmological test with the geometric distortion focusing on an ambiguous factor of the evolution of bias. Starting from defining estimators for the…
