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…
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…
Cosmological consequences of a scalar field with oscillating equation of state. III. Unifying inflation with dark energy and small tensor-to-scalar ratio
S. X. Tian, Zong-Hong Zhu
We investigate the inflationary consequences of the oscillating dark energy model proposed by Tián [\href{https://doi.org/10.1103/PhysRevD.101.063531}{Phys. Rev. D {\bf 101}, 06353…
Probing compact dark matter with gravitational wave fringes detected by the Einstein Telescope
Kai Liao, Shuxun Tian, Xuheng Ding
Unlike the electromagnetic radiation from astrophysical objects, gravitational waves (GWs) from binary star mergers have much longer wavelengths and are coherent. For ground-based…
Cosmological consequences of a scalar field with oscillating equation of state: A possible solution to the fine-tuning and coincidence problems
S. X. Tián
We propose a new dark energy model for solving the cosmological fine-tuning and coincidence problems. A default assumption is that the fine-tuning problem disappears if we do not i…
Can continuous density profile correctly describe strong gravitational lensing?
Shuxun Tian
Strong gravitational lensing is an important tool to probe the universe. In the theoretical analysis of gravitational lensing, it is assumed that continuous density profile can cor…
