Artificial Precision Polarization Array: Sensitivity for the axion-like dark matter with clock satellites
Hanyu Jiang, Baoyu Xu, Yun-Long Zhang
The approaches to searching for axion-like signals based on pulsars include observations with pulsar timing arrays (PTAs) and pulsar polarization arrays (PPAs). However, these meth…
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…
Detecting Chiral Gravitational Wave Background with a Dipole Pulsar Timing Array
Baoyu Xu, Hanyu Jiang, Rong-Gen Cai +2
The pulsar timing array (PTA) is a powerful technique for detecting nanohertz gravitational wave backgrounds (GWBs). However, conventional PTAs lack sensitivity to parity violation…
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…
