Measuring the Moving Lens Effect with Wide-Separation Lensed Quasars
Yupeng Zhang, Shuxun Tian, Zhengxiang Li
The transverse motion of a gravitational potential induces frequency shifts in photons propagating through it, giving rise to the moving-lens effect and providing a probe of transv…
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…
Effects of formation channels and gravitational lensing on stochastic gravitational wave background
Xin-yi Lin, Zhengxiang Li
Two primary formation channels for black holes have been proposed: the astrophysical channel, driven by the collapse of massive stars, and the primordial channel, involving their d…
Evidence for Intermediate-Mass Black Holes From Microlensing Signatures in CHIME/FRB catalog 2
Huan Zhou, Zhengxiang Li, Cheng-Gang Shao +4
Intermediate-mass black holes (IMBHs) are the missing link in the cosmic hierarchy of black holes, bridging the gap between stellar-mass black holes and supermassive ones. They als…
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…
