Constraining axion inflation with gravitational waves across 29 decades in frequency
Peter Adshead, John T. Giblin, Mauro Pieroni +1
We demonstrate that gravitational waves generated by efficient gauge preheating after axion inflation generically contribute significantly to the effective number of relativistic d…

Constraining axion inflation with gravitational waves from preheating
Peter Adshead, John T. Giblin, Mauro Pieroni +1
We study gravitational wave production from gauge preheating in a variety of inflationary models, detailing its dependence on both the energy scale and the shape of the potential.…
