Relativistic cosmological hydrodynamics
J. Hwang, H. Noh
We investigate the relativistic cosmological hydrodynamic perturbations. We present the general large scale solutions of the perturbation variables valid for the general sign of th…

Density Spectrums from Kinetic Inflations
J. Hwang, H. Noh
The pole-like accelerated expansion stages purely driven by the coupling between the gravity and the dilaton field without referring to the potential term can be realized in a clas…

Cosmological Perturbations with Multiple Scalar Fields
J. Hwang
In this brief note we present a set of equations describing the evolution of perturbed scalar fields in a cosmological spacetime with multiple scalar fields. We take into account o…
