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…
Probing Spin-2 Ultralight Dark Matter with Space-based Gravitational Wave Detectors in the mHz Regime
Jing-Rui Zhang, Ju Chen, Heng-Sen Jiao +2
Spin-2 ultralight dark matter (ULDM) is a viable dark matter candidate and it can be constrained using gravitational wave (GW) observations. In this paper, we investigate the detec…
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…
Chiral Gravitational Wave Background from Audible Axion via Nieh-Yan Term
Baoyu Xu, Keyi Ding, Hong Su +2
Axions and axion-like particles can be probed through gravitational waves indirectly, often referred to as "audible axions". The usual concept of audible axion relies on the coupli…
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…
