Cosmological Perturbations on a Bouncing Brane

Brandenberger, Robert, Firouzjahi, Hassan, Saremi, Omid

Understand

The cosmological perturbations on a bouncing brane are studied.

  • The brane is moving inside a Klebanov-Strassler throat where the infra-red region of the geometry is smoothly cut off.
  • For an observer confined to the world-volume of the brane, this results in a non-singular bouncing mirage cosmology.
  • We have calculated the scalar perturbations corresponding to the normal displacements of the brane.
