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…

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…
