Ekpyrosis in Quantum Gravitational Anisotropic Bouncing Models
Rachel Brown, A. Meenakshi McNamara, Sahil Saini +1
We explore the isotropization of a model anisotropic universe in the bouncing models using the ekpyrotic potential without assuming initial conditions corresponding to an ekpyrotic…
Insights into Binary Neutron Star Merger Simulations: A Multi-Code Comparison
Maria C. Babiuc Hamilton, William A. Messman
Gravitational Wave (GW) signals from Binary Neutron Star (BNS) mergers provide critical insights into the properties of matter under extreme conditions. Due to the scarcity of obse…
One EURO for Uranus: the Elliptical Uranian Relativity Orbiter mission
Lorenzo Iorio, Athul P. Girija, Daniele Durante
Recent years have seen increasing interest in sending a mission to Uranus, visited so far only by Voyager 2 in 1986. EURO (Elliptical Uranian Relativity Orbiter) is a preliminary m…
Symmetry of Generalized Randall-Sundrum Model and Distribution of 3-Branes in Six-Dimensional Spacetime
Sheng-Fei Feng, Chang-Yu Huang, Yong-Chang Huang +2
A generalization from the usual -dimensional two-brane Randall-Sundrum (RS) model to a -dimensional multi-brane RS model is presented. The extra dimensions are extended from…
On reversal of centrifugal acceleration in special relativity
Maxim Lyutikov
The basic principles of General Theory of Relativity historically have been tested in gedanken experiments in rotating frame of references. One of the key issues, which still evoke…
Gravity-induced birefringence within the framework of Poincare gauge theory
Oliver Preuss, Sami K. Solanki, M. P. Haugan +1
Gauge theories of gravity provide an elegant and promising extension of general relativity. In this paper we show that the Poincaré gauge theory exhibits gravity-induced birefringe…
