Relic gravitational waves
R. A. Battye, E. P. S. Shellard
The next generation of gravitational wave detectors holds out the prospect of detecting a stochastic gravitational background generated in the very early universe. In this article,…
Large Angular Scale CMB Anisotropy Induced by Cosmic Strings
B. Allen, R. R. Caldwell, E. P. S. Shellard +2
We simulate the anisotropy in the cosmic microwave background (CMB) induced by cosmic strings. By numerically evolving a network of cosmic strings we generate full-sky CMB temperat…
Relic Gravitational Waves from Cosmic Strings: Updated Constraints and Opportunities for Detection
R. R. Caldwell, R. A. Battye, E. P. S. Shellard
We examine the spectrum of gravitational radiation emitted by a network of cosmic strings, with emphasis on the observational constraints and the opportunities for detection. The a…
Averaged Methods for Vortex-String Evolution
C. J. A. P. Martins, E. P. S. Shellard
We discuss friction-dominated vortex-string evolution using a new analytic model recently developed by the authors. By treating the average string velocity, as well as the characte…
Primordial gravitational waves : a probe of the early universe
R. A. Battye, E. P. S. Shellard
We discuss the potential cosmological role of gravitational wave astronomy as a probe of the very early universe. The next generation of detectors - now in production - may be able…
Quantitative String Evolution
C. J. A. P. Martins, E. P. S. Shellard
An analytic model of long string network evolution, recently developed by the authors, is presented in detail, and modified to describe string loop evolution. By treating the avera…
