Deflection angle and lensing signature of covariant f(T) gravity
Xin Ren, Yaqi Zhao, Emmanuel N. Saridakis +1
We calculate the deflection angle, as well as the positions and magnifications of the lensed images, in the case of covariant gravity. We first extract the spherically symme…
Data-driven Reconstruction of the Late-time Cosmic Acceleration with f(T) Gravity
Xin Ren, Thomas Hong Tsun Wong, Yi-Fu Cai +1
We use a combination of observational data in order to reconstruct the free function of f(T) gravity in a model-independent manner. Starting from the data-driven determined dark-en…
Testing the equivalence principle via the shadow of black holes
Chunlong Li, Sheng-Feng Yan, Lingqin Xue +5
We study the equivalence principle, regarded as the cornerstone of general relativity, by analyzing the deformation observable of black hole shadows. Such deformation can arise fro…
Implications of the possible 21-cm line excess at cosmic dawn on dynamics of interacting dark energy
Chunlong Li, Xin Ren, Martiros Khurshudyan +1
In this paper we study implications of the possible excess of 21-cm line global signal at the epoch of cosmic dawn on the evolutions of a class of dynamically interacting dark ener…
