Correlations for an anisotropic polarized stochastic gravitational wave background in pulsar timing arrays

Reginald Christian Bernardo, Guo-Chin Liu, Kin-Wang Ng

The recent compelling observation of the nanohertz stochastic gravitational wave background has brought to light a new galactic arena to test gravity. In this paper, we derive a fo…

pygwb: Python-based library for gravitational-wave background searches

Arianna I. Renzini, Alba Romero-Rodrguez, Colm Talbot +31

The collection of gravitational waves (GWs) that are either too weak or too numerous to be individually resolved is commonly referred to as the gravitational-wave background (GWB).…

Overlap reduction functions for a polarized stochastic gravitational-wave background in the Einstein Telescope-Cosmic Explorer and the LISA-Taiji networks

Guo-Chin Liu, Kin-Wang Ng

The detection of gravitational waves from the coalescences of binary compact stars by current interferometry experiments has opened up a new era of gravitational-wave astrophysics…

Deep learning for intermittent gravitational wave signals

Takahiro S. Yamamoto, Sachiko Kuroyanagi, Guo-Chin Liu

The ensemble of unresolved compact binary coalescences is a promising source of the stochastic gravitational wave (GW) background. For stellar-mass black hole binaries, the astroph…

Measuring the cosmological density field twice: A novel test of dark energy using the CMB quadrupole

Kiyotomo Ichiki, Kento Sumiya, Guo-Chin Liu

The scattering of cosmic microwave background (CMB) radiation in galaxy clusters induces polarization signals according to the quadrupole anisotropy in the photon distribution at t…

Timing-residual power spectrum of a polarized stochastic gravitational-wave background in pulsar-timing-array observation

Guo-Chin Liu, Kin-Wang Ng

We study the observation of stochastic gravitational-wave background (SGWB) made by pulsar-timing arrays in the spherical harmonic space. Instead of using the Shapiro time delay, w…
