Strong lensing as a probe of braneworld
Yi Zhang, Hong Liu, Dan Wen +1
For the first time, we use the Event Horizon Telescope (EHT) data to constrain the parameters of braneworld black holes which constrain …
Gravitational anomalies of fermionic higher-spin fields
Victor Lekeu, Yi Zhang
Using the Atiyah-Singer index theorem, we formally compute gravitational anomalies for fermionic higher-spin fields in two, six and ten dimensions, as well as the U(1) mixed gauge-…
Distinguish the model from CDM model with Gravitational Wave observations
Yi Zhang, Hongsheng Zhang
Separately, neither electromagnetic (EM) observations nor gravitational wave (GW) observations can distinguish between the model and the CDM model effectively. To break t…
Towards a sound massive cosmology
Hongsheng Zhang, Ya-Peng Hu, Yi Zhang
It is known that de Rham-Gabadadze-Tolley (dRGT) massive gravity does not permit a homogeneous and isotropic universe with flat or spherical spatial metrics. We demonstrate that a…
Cosmological Model Independent Time Delay Method
Yi Zhang, Xuewen Liu, Jingzhao Qi +1
We propose a Cosmological Model Independent Time Delay (CMITD) method where the Lorentz invariance violation (LIV) variable is constructed by observational data instead of c…
Dynamical spacetimes in conformal gravity
Hongsheng Zhang, Yi Zhang, Xin-Zhou Li
The conformal gravity remarkably boosts our prehension of gravity theories. We find a series of dynamical solutions in the -conformal gravity, including generalized Schwarzsch…
Higgs Inflation on Braneworld
Hongsheng Zhang, Yi Zhang, Xin-Zhou Li
We discuss a Higgs inflation model in the warped DGP braneworld background. It generates reasonable primordial perturbations. At the same time with enhanced non-minimal coupling it…
