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…

Cosmological structures in generalized gravity
J. Hwang
In a class of generalized gravity theories with general couplings between the scalar field and the scalar curvature in the Lagrangian, we describe the quantum generation and the cl…

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…
