Lensing and CMB Anisotropies by Cosmic Strings at a Junction
arXiv:0710.1636 · doi:10.1103/PhysRevD.77.083502
Abstract
The metric around straight arbitrarily-oriented cosmic strings forming a stationary junction is obtained at the linearized level. It is shown that the geometry is flat. The sum rules for lensing by this configuration and the anisotropies of the CMB are obtained.
