Leading-order gravitational time delay of massive particles by a moving Schwarzschild lens
Guansheng He, Wenbin Lin, Yi Xie
The leading-order gravitational time delay of relativistic neutral massive particles (e.g., neutrinos or high-energy cosmic-ray particles) caused by a moving Schwarzschild black ho…
Weak and strong deflection gravitational lensings by a charged Horndeski black hole
Cheng-Yi Wang, Yu-Fu Shen, Yi Xie
A charged black hole was predicted by the Einstein--Horndeski--Maxwell theory. In order to provide its observational signatures, we investigate its weak and strong deflection gravi…
Strong deflection gravitational lensing by a modified Hayward black hole
Shan-Shan Zhao, Yi Xie
A modified Hayward black hole is a nonsingular black hole. It is proposed to form when the pressure generated by quantum gravity can stop matter's collapse as the matter reaches Pl…
Strong gravitational field time delay for photons coupled to Weyl tensor in a Schwarzschild black hole
Xu Lu, Feng-Wei Yang, Yi Xie
We analyse strong gravitational field time delay for photons coupled to the Weyl tensor in a Schwarzschild black hole. By making use of the method of strong deflection limit, we fi…
Strong field gravitational lensing by a charged Galileon black hole
Shan-Shan Zhao, Yi Xie
Strong field gravitational lensings are dramatically disparate from those in the weak field by representing relativistic images due to light winds one to infinity loops around a le…
Improved upper bounds on Kaluza-Klein gravity with current Solar System experiments and observations
Xue-Mei Deng, Yi Xie
As an extension of previous works on classical tests of Kaluza-Klein (KK) gravity and as an attempt to find more stringent constraints on this theory, its effects on physical exper…
