Constraints on Gauge Field Production during Inflation
Sami Nurmi, Martin S. Sloth
In order to gain new insights into the gauge field couplings in the early universe, we consider the constraints on gauge field production during inflation imposed by requiring that…
Implications of the Planck bispectrum constraints for the primordial trispectrum
Christian T. Byrnes, Sami Nurmi, Gianmassimo Tasinato +1
The new Planck constraints on the local bispectrum parameter fnl are about 10^5 times tighter than the current constraints on the trispectrum parameter gnl, which means that the al…
A non-Gaussian landscape
Sami Nurmi, Christian T. Byrnes, Gianmassimo Tasinato
Primordial perturbations with wavelengths greater than the observable universe shift the effective background fields in our observable patch from their global averages over the inf…
