Einstein-Yang-Mills Theory: Gauge Invariant Charges and Linearization Instability
Emel Altas, Ercan Kilicarslan, Bayram Tekin
We construct the gauge-invariant electric and magnetic charges in Yang-Mills theory coupled to cosmological General Relativity (or any other geometric gravity), extending the flat…
Approximate analytical description of apparent horizons for initial data with momentum and spin
Emel Altas, Bayram Tekin
We construct analytical initial data for a slowly moving and rotating black hole for generic orientations of the linear momentum and the spin. We solve the Hamiltonian constraint a…
Bowen-York Model Solution Redux
Emel Altas, Bayram Tekin
Initial value problem in General Relativity is often solved numerically; with only a few exceptions one of which is the "model" solution of Bowen and York where an analytical form…
Energy and Angular Momentum in D dimensional Kerr-AdS black holes-new formulation
Emel Altas
Recently it was shown that the conserved charges of asymptotically anti de Sitter spacetimes can be written in an explicitly gauge-invariant way in terms of the linearized Riemann…
Non-stationary Energy in General Relativity
Emel Altas, Bayram Tekin
Using the time evolution equations of (cosmological) General Relativity in the first order Fischer-Marsden form, we construct an integral that measures the amount of non-stationary…
Second Order Gauge Invariant Perturbation Theory and Conserved Charges in Cosmological Einstein's Gravity
Emel Altas
Recently a new approach in constructing the conserved charges in cosmological Einstein's gravity was given. In this new formulation, instead of using the explicit form of the field…
