Signatures of Extended Dark Energy Parametrisations in Structure Formation under Background Constraints
Greco A. Peña, Mario H. Amante, Javier Chagoya +3
We study structure formation in alternative cosmological models constrained by background observations, including CDM, wCDM, the Chevallier-Polarski-Linder parametrisation and a…
The frame-dragging vector potential on galaxy scales from Dark-Matter-only Newtonian -body simulations
William Beordo, Marco Bruni, Cristian Barrera-Hinojosa +1
Effects of General Relativity are usually neglected in the non-linear evolution of structures, where Newtonian -body simulations are traditionally employed. In the post-Friedman…
ExaGRyPE: Numerical General Relativity Solvers Based upon the Hyperbolic PDEs Solver Engine ExaHyPE
Han Zhang, Baojiu Li, Tobias Weinzierl +1
ExaGRyPE describes a suite of solvers for numerical relativity, based upon ExaHyPE 2, the second generation of our Exascale Hyperbolic PDE Engine. The presented generation of ExaGR…
An extension of C++ with memory-centric specifications for HPC to reduce memory footprints and streamline MPI development
Pawel K. Radtke, Cristian G. Barrera-Hinojosa, Mladen Ivkovic +1
C++ leans towards a memory-inefficient storage of structs: The compiler inserts padding bits, while it is not able to exploit knowledge about the range of integers, enums or bitset…
Minkowski Functionals of Large-Scale Structure as a Probe of Modified Gravity
Aoxiang Jiang, Wei Liu, Baojiu Li +3
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 robus…
Looking for a twist: probing the cosmological gravitomagnetic effect via weak lensing-kSZ cross correlations
Cristian Barrera-Hinojosa, Baojiu Li, Yan-Chuan Cai
General relativity predicts that the rotational momentum flux of matter twists the spacetime via a vector gravitomagnetic (frame-dragging) field, which remains undetected in cosmol…
