Shortcut in codimension-2 brane cosmology in light of GW170817
Zi-Chao Lin, Hao Yu, Yu-Xiao Liu
In this paper, our universe is regarded as a codimension-2 brane embedded in a noncompact six-dimensional Anti-de Sitter (AdS) spacetime. We derive the gravitational horizon radius…
Constraint on the radius of five-dimensional dS spacetime with GW170817 and GRB 170817A
Zi-Chao Lin, Hao Yu, Yu-Xiao Liu
The recent detections of the gravitational wave (GW) event GW170817 and its electromagnetic counterpart GRB 170817A produced by a binary neutron star (NS) merger is a new milestone…
Particle and entropy production in the Running Vacuum Universe
Joan Sola, Hao Yu
We study particle production and the corresponding entropy increase in the context of cosmology with dynamical vacuum. We focus on the particular form that has been called "running…
Thick brane in reduced Horndeski theory
Qi-Ming Fu, Hao Yu, Li Zhao +1
Horndeski theory is the most general scalar-tensor theory retaining second-order field equations, although the action includes higher-order terms. This is achieved by a special cho…
Gravitational waves and extra dimensions: a short review
Hao Yu, Zi-Chao Lin, Yu-Xiao Liu
We give a brief review on the recent development of gravitational waves in extra-dimensional theories of gravity. Studying extra-dimensional theories with gravitational waves provi…
Scalar particle production in a simple Horndeski theory
Hao Yu, Wen-Di Guo, Ke Yang +1
The scalar particle production through a scalar field non-minimally coupled with geometry is investigated in the context of a spatially homogeneous and isotropic universe. In this…
Statefinder diagnostic and constraints on the Palatini f(R) gravity theories
Shu-Lei Cao, Song Li, Hao-Ran Yu +1
We focus on a series of gravity theories in Palatini formalism to investigate the probabilities of producing the late-time acceleration for the flat Friedmann-Robertson-Walk…
Probing extra dimension through gravitational wave observations of compact binaries and their electromagnetic counterparts
Hao Yu, Bao-Min Gu, Fa Peng Huang +3
The future gravitational wave (GW) observations of compact binaries and their possible electromagnetic counterparts may be used to probe the nature of the extra dimension. It is wi…
Gravitational resonances on -brane
Hao Yu, Yuan Zhong, Bao-Min Gu +1
In this paper, we investigate various -brane models and compare their gravitational resonance structures with the corresponding general relativity (GR)-branes. {Starting from…
