Probing the nature of cosmic acceleration
Hongsheng Zhang, Heng Yu, Hyerim Noh +1
The cosmic acceleration is one of the most significant cosmological discoveries over the last century. The two categories of explanation are exotic component (dark energy) and modi…
Nonlinear cosmological power spectra in Einstein's gravity
Hyerim Noh, Jai-chan Hwang
Is Newton's gravity sufficient to handle the weakly nonlinear evolution stages of the cosmic large-scale structures? Here we resolve the issue by analytically deriving the density…
COBE-DMR constraints on a inflation model with non-minimal scalar field
J. Hwang, H. Noh
We derive the power spectra of the scalar- and tensor-type structures generated in a chaotic-type inflation model based on non-minimally coupled scalar field with a self interactio…
Newtonian Limits of the Relativistic Cosmological Perturbations
J. Hwang, H. Noh
Relativistic cosmological perturbation analyses can be made based on several different fundamental gauge conditions. In the pressureless limit the variables in certain gauge condit…
