Brane World Linearized Cosmic String Gravity

[Stephen C. Davis]

Title: Brane World Linearized Cosmic String Gravity

Author(s): Stephen C. Davis

The gravitational properties of cosmic strings in the Randall-Sundrum brane
world scenario are investigated. Using a gauge in which the brane remains
straight, the leading order corrections to the metric on the brane are
determined. In contrast to their non-brane equivalents, these strings have an
attractive 1/r^2 potential and a radially dependent deficit angle. These two
effects alter many cosmological properties of the string, such as the formation
of double images. As a result of the attractive force the string will collect
matter as it moves through space.
