Cosmic anisotropic hair of nonlocal RT gravity
Jiajun Zhou, Shuxun Tian, Zong-Hong Zhu
Nonlocal RT gravity has proven effective in explaining the late-time cosmic acceleration while remaining consistent with local gravity tests. However, most previous cosmological st…

Lensed fast radio bursts as a probe of time-varying gravitational potential induced by wave dark matter
Ran Gao, Shuxun Tian, Zhengxiang Li +4
Ultralight bosonic wave dark matter (DM) is preponderantly contesting the conventional cold DM paradigm in predicting diverse and rich phenomena on small scales. For a DM halo made…

A robust test of general relativity at the galactic scales by combining strong lensing systems and gravitational wave standard sirens
Tonghua Liu, Marek Biesiada, Shuxun Tian +1
The measurement of the parametrized post-Newtonian parameter is a robust test of general relativity (GR). In some modified theories of gravity, may ev…
