Gravitational Waves from Oscillon Preheating

1 code implementation22 Apr 2013 Shuang-Yong Zhou, Edmund J. Copeland, Richard Easther, Hal Finkel, Zong-Gang Mou, Paul M. Saffin

However, a significant stochastic gravitational wave background may be generated during preheating itself (i. e, when oscillons are forming), and in this case the characteristic size of the oscillons is imprinted on the gravitational wave power spectrum, which has multiple, distinct peaks.
