Broadband Chiral Primordial Gravitational Waves from Constant-roll Inflation in Parity-violating Symmetric Teleparallel Gravity
Xu Zhang, Chang Liu, Chengjie Fu
We investigate primordial gravitational waves (GWs) generated during constant-roll inflation in a parity-violating extension of symmetric teleparallel gravity. The parity-violating…
Test Gravitational-Wave Polarizations with Space-Based Detectors
Jun-Shuai Wang, Chang Liu, Ju Chen +1
In this work, we systematically investigate the capability of space-based gravitational wave detectors in constraining parameters of non-tensor polarization modes. Using Bayesian i…
Detectability of the chiral gravitational wave background from audible axions with the LISA-Taiji network
Hong Su, Baoyu Xu, Ju Chen +2
The chiral gravitational wave background (GWB) can be produced by axion-like fields in the early universe. We perform parameter estimation for two types of chiral GWB with the LISA…
Alternative LISA-TAIJI networks: Detectability of the Parity Violation in Stochastic Gravitational Wave Background
Ju Chen, Chang Liu, Yun-Long Zhang +1
The detection of parity violation in the isotropic stochastic gravitational wave background (SGWB) will serve a crucial probe for new physics, particularly in parity-violating theo…
Circularly Polarized Gravitational Wave Background Search with a Network of Space-borne Triangular Detectors
Ju Chen, Chang Liu, Yun-Long Zhang
Circularly polarized gravitational wave backgrounds are predicted in many well-motivated models of inflation and phase transitions involving spontaneous parity violation. In this w…
Probing modified gravitational-wave propagation with extreme mass-ratio inspirals
Chang Liu, Danny Laghi, Nicola Tamanini
Extreme mass-ratio inspirals (EMRIs), namely binary systems composed of a massive black hole and a compact stellar-mass object, are anticipated to be among the gravitational wave (…
Prospects for Taiji to detect a gravitational-wave background from cosmic strings
Zu-Cheng Chen, Qing-Guo Huang, Chang Liu +6
Recently, multiple pulsar timing array collaborations have presented compelling evidence for a stochastic signal at nanohertz frequencies, potentially originating from cosmic strin…
