Thick branes in Born-Infeld determinantal gravity in Weitzenböck spacetime
Ke Yang, Hao Yu, Yi Zhong
By adopting the idea of Born-Infeld electromagnetism, the Born-Infeld determinantal gravity in Weitzenböck spacetime provides a way to smooth the Big Bang singularity at the classi…
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…
Observational search for primordial chirality violations using galaxy angular momenta
Pavel Motloch, Ue-Li Pen, Hao-Ran Yu
We search for evidence of primordial chirality violation in the galaxy data from the Sloan Digital Sky Survey by comparing how strongly directions of galaxy angular momenta correla…
Correlating galaxy shapes and initial conditions: an observational study
Pavel Motloch, Ue-Li Pen, Hao-Ran Yu
Using data from the Sloan Digital Sky Survey we study correlations between directions of galaxy angular momenta determined from images of spiral galaxies and various observables de…
Constraints on running vacuum models with the baryon-to-photon ratio
Hao Yu, Ke Yang, Jin Li
We study the influence of running vacuum on the baryon-to-photon ratio in running vacuum models (RVMs). When there exists a non-minimal coupling between photons and other matter in…
Spin Mode Reconstruction in Lagrangian Space
Qiaoya Wu, Hao-Ran Yu, Shihong Liao +1
Galaxy angular momentum directions (spins) are observable, well described by the Lagrangian tidal torque theory, and proposed to probe the primordial universe. They trace the spins…

The moduli spaces of compact and connected Riemann surfaces has been a central topic in modern mathematics in recent years. Thus their homological dimensions become important invar…
Neutrino effects on the morphology of cosmic large-scale structure
Yu Liu, Yu Yu, Hao-Ran Yu +1
In this work, we propose a powerful probe of neutrino effects on the large-scale structure (LSS) of the Universe, i.e., Minkowski functionals (MFs). The morphology of LSS can be fu…
Observational detection of correlation between galaxy spins and initial conditions
Pavel Motloch, Hao-Ran Yu, Ue-Li Pen +1
Galaxy spins can be predicted from the initial conditions in the early Universe through the tidal tensor twist. In simulations, their directions are well preserved through cosmic t…
CUBE -- Towards an Optimal Scaling of Cosmological N-body Simulations
Shenggan Cheng, Hao-Ran Yu, Derek Inman +3
N-body simulations are essential tools in physical cosmology to understand the large-scale structure (LSS) formation of the Universe. Large-scale simulations with high resolution a…
Simulating the Cosmic Neutrino Background using Collisionless Hydrodynamics
Derek Inman, Hao-ran Yu
The cosmic neutrino background is an important component of the Universe that is difficult to include in cosmological simulations due to the extremely large velocity dispersion of…

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…
