Asymptotically Friedmann self-similar scalar field solutions with potential
Masanori Kyo, Tomohiro Harada, Hideki Maeda
We investigate self-similar solutions which are asymptotic to the Friedmann universe at spatial infinity and contain a scalar field with potential. The potential is required to be…
Static and symmetric wormholes respecting energy conditions in Einstein-Gauss-Bonnet gravity
Hideki Maeda, Masato Nozawa
Properties of -dimensional static wormhole solutions are investigated in Einstein-Gauss-Bonnet gravity with or without a cosmological constant . We assume that the spa…
Dynamical black holes with symmetry in Einstein-Gauss-Bonnet gravity
Masato Nozawa, Hideki Maeda
We explore various aspects of dynamical black holes defined by a future outer trapping horizon in -dimensional Einstein-Gauss-Bonnet gravity. In the present paper, we ass…
Generalized Misner-Sharp quasi-local mass in Einstein-Gauss-Bonnet gravity
Hideki Maeda, Masato Nozawa
We investigate properties of a quasi-local mass in a higher-dimensional spacetime having symmetries corresponding to the isomertries of an -dimensional maximally symmetric s…
Self-similar cosmological solutions with dark energy. II: black holes, naked singularities and wormholes
Hideki Maeda, Tomohiro Harada, B. J. Carr
We use a combination of numerical and analytical methods, exploiting the equations derived in a preceding paper, to classify all spherically symmetric self-similar solutions which…
Self-similar cosmological solutions with dark energy. I: formulation and asymptotic analysis
Tomohiro Harada, Hideki Maeda, B. J. Carr
Based on the asymptotic analysis of ordinary differential equations, we classify all spherically symmetric self-similar solutions to the Einstein equations which are asymptotically…
