Dynamics and Frequency Conversion of Accreting Axion Clouds
Ximeng Li, Zhen Zhong, Yifan Chen +3
Axion fields can form exponentially growing gravitational clouds around compact objects through self-interaction-driven relaxation of ambient axion waves. As the field amplitude ap…
Probing Ultralight Axion-like Dark Matter: A Pulsar Timing Arrays-Pulsar Polarization Arrays Synergy
Ximeng Li, Yonghao Liu, Zu-Cheng Chen +9
Ultralight axionlike dark matter (ALDM) is a leading candidate in the dark matter realm, characterized by its prominent wave properties on astronomical scales. Pulsar timing arrays…
Probing Boson Clouds with Supermassive Black Hole Binaries
Ximeng Li, Jing Ren, Xi-Li Zhang
Rotating black holes can generate boson clouds via superradiance when the boson's Compton wavelength is comparable to the black hole's size. In binary systems, these clouds can pro…
Probing light scalars with not quite black holes
Ximeng Li, Jing Ren
The rapid progress in gravitational wave astronomy has provided an opportunity for investigating the presence of long-range scalar forces that exclusively manifest around astrophys…
