ExaGRyPE describes a suite of solvers and solver ingredients for numerical relativity that are based upon ExaHyPE 2, the second generation of our Exascale Hyperbolic PDE Engine. Numerical relativity simulations are crucial in resolv... Read More about ExaGRyPE: Numerical general relativity solvers based upon the hyperbolic PDEs solver engine ExaHyPE.

Minkowski functionals of large-scale structure as a probe of modified gravity (2024)
Journal Article
Jiang, A., Liu, W., Fang, W., Li, B., Barrera-Hinojosa, C., & Zhang, Y. (2024). Minkowski functionals of large-scale structure as a probe of modified gravity. Physical Review D, 109(8), Article 083537. https://doi.org/10.1103/physrevd.109.083537

In this study, we explore the potential of utilizing the four Minkowski functionals, which can fully describe the morphological properties of the large-scale structures, as a robust tool for investigating the modified gravity, particularly on nonline...

We investigate the transverse modes of the gravitational and velocity fields in Λ cold dark matter, based on a high-resolution simulation performed using the adaptive-mesh refinement general-relativistic N-body code GRAMSES. We study the generation o... Read More about Vector modes in ΛCDM: the gravitomagnetic potential in dark matter haloes from relativistic N-body simulations.

Numerical solutions to Einstein’s equations in a shearing-dust universe: a code comparison (2020)
Journal Article

A number of codes for general-relativistic simulations of cosmological structure formation have been developed in recent years. Here we demonstrate that a sample of these codes produce consistent results beyond the Newtonian regime. We simulate solut...

We study the imprints of an effective dark energy fluid in the large scale structure of the universe through the observed angular power spectrum of galaxies in the relativistic regime. We adopt the phenomenological approach that introduces two parame... Read More about Relativistic effects in the large-scale structure with effective dark energy fluids.
