Lensing and CMB Anisotropies by Cosmic Strings at a Junction

Brandenberger, Robert, Firouzjahi, Hassan, Karouby, Johanna

Understand

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.
