Newtonian versus relativistic nonlinear cosmology
Jai-chan Hwang, Hyerim Noh
Both for the background world model and its linear perturbations Newtonian cosmology coincides with the zero-pressure limits of relativistic cosmology. However, such successes in N…

Why Newton's gravity is practically reliable in the large-scale cosmological simulations
J. Hwang, H. Noh
Until now, it has been common to use Newton's gravity to study the non-linear clustering properties of the large-scale structures. Without confirmation from Einstein's theory, howe…

Cosmological nonlinear hydrodynamics with post-Newtonian corrections
Jai-chan Hwang, Hyerim Noh, Dirk Puetzfeld
The post-Newtonian (PN) approximation, based on the assumptions of weak gravitational fields and slow motions, provides a way to estimate general relativistic effects in the fully…
