Detectable gravitational wave signals from inflationary preheating

Blog Article

We consider gravitational wave (GW) production during preheating in hybrid inflation models where an axion-like waterfall field couples to Abelian gauge fields.Based on a linear analysis, we find that the GW signal from such models can be within the reach of a variety of foreseeable GW experiments such as Connecting community-based monitoring to Arctic environmental decision-making and governance: A systematic scoping review of the literature LISA, AEDGE, ET and CE, and is close to Sequential Movie Genre Prediction Using Average Transition Probability with Clustering that of LIGO A+, both in terms of frequency range and signal strength.Furthermore, the resultant GW signal is helically polarized and thus may distinguish itself from other sources of stochastic GW background.Finally, such models can produce primordial black holes that can compose dark matter and lead to merger events detectable by GW detectors.
