Gravitational Lensing Predictions from Wave Simulations of Fuzzy Dark Matter
Jiajun Zhou, Zhengxiang Li, Amruth Alfred +3
In the cold dark matter paradigm, ultra-light particles are emerging as strong contenders to conventional massive particles. A unique prediction of dark matter comprising such ultr…
Constraints on Primordial Black Hole Dressed by Dark Matter Halo from Microlensing Effect of Fast Radio Bursts
Hong-Rui Tao, Huan Zhou, Cheng-Gang Shao +2
Primordial black holes (PBHs) are not only considered as a candidate for dark matter, but also as potential sources of gravitational waves from binary black hole mergers by the LIG…
Avoiding recollapse in an open-AdS universe via a self-tuning-like mechanism
Yupeng Zhang, Shuxun Tian, Zhengxiang Li
We study whether an open FLRW universe with a negative cosmological constant can evade the eventual recollapse characteristic of an AdS-type universe. Within a power-law realizatio…
FRB cosmology with the RM-PRS Luminosity Correlation
Ran Gao, He Gao, Zhengxiang Li +1
Fast Radio Bursts (FRBs) have emerged as a powerful tool for cosmological studies, particularly through the dispersion measure-redshift () relation. This work propos…
Exploring primordial curvature perturbation on small scales with the lensing effect of fast radio bursts
Huan Zhou, Zhengxiang Li, Zong-Hong Zhu
Cosmological observations, e.g., cosmic microwave background, have precisely measured the spectrum of primordial curvature perturbation on larger scales, but smaller scales are sti…
Hunting Galactic Axion Dark Matter with Gravitationally Lensed Fast Radio Bursts
Ran Gao, Zhengxiang Li, Kai Liao +3
Ultralight axion or axionlike particles are one of the most promising candidates for dark matter because they are a well-motivated solution for the theoretical strong problem…
