Perfect fluid with shear viscosity and spacetime evolution
Inyong Cho, Rajibul Shaikh
We investigate the anisotropic evolution of spacetime driven by perfect fluid with off-diagonal shear-viscosity components. We consider the simplest form of the equation of state f…
Second-order energy-momentum tensor of a scalar field
Inyong Cho, Jinn-Ouk Gong, Seung Hun Oh
We investigate the second-order effective energy-momentum tensor (2EMT) constructed by the quadratic terms of the linear scalar cosmological perturbations while the universe is dom…
Numerical Study of Instability of Fluid Black Holes
Inyong Cho, Dong-Ho Park
Recently neutral and charged black-hole solutions were found for static perfect fluid with the equation of state , for fluid only as well as for fluid in the presence…
Second-order effective energy-momentum tensor of gravitational scalar perturbations with perfect fluid
Inyong Cho, Jinn-Ouk Gong, Seung Hun Oh
We investigate the second-order gravitational scalar perturbations for a barotropic fluid. We derive the effective energy-momentum tensor described by the quadratic terms of the gr…
Fluid Black Holes with Electric Field
Inyong Cho
We investigate the gravitational field of static perfect-fluid in the presence of electric field. We adopt the equation of state for the fluid in order to consider t…
Simple Black Holes with Anisotropic Fluid
Inyong Cho, Hyeong-Chan Kim
We study a spherically symmetric spacetime made of anisotropic fluid of which radial equation of state is given by . This provides analytic solutions and a good opportuni…
