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…
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…
