Vanishing of local non-Gaussianity in canonical single field inflation
Rafael Bravo, Sander Mooij, Gonzalo A. Palma +1
We study the production of observable primordial local non-Gaussianity in two opposite regimes of canonical single field inflation: attractor (standard single field slow-roll infla…
A generalized non-Gaussian consistency relation for single field inflation
Rafael Bravo, Sander Mooij, Gonzalo A. Palma +1
We show that a perturbed inflationary spacetime, driven by a canonical single scalar field, is invariant under a special class of coordinate transformations together with a field r…
Consistency relations for sharp inflationary non-Gaussian features
Sander Mooij, Gonzalo A. Palma, Grigoris Panotopoulos +1
If cosmic inflation suffered tiny time-dependent deviations from the slow-roll regime, these would induce the existence of small scale-dependent features imprinted in the primordia…
Consistency relations for sharp features in the primordial spectra
Sander Mooij, Gonzalo A. Palma, Grigoris Panotopoulos +1
We study the generation of sharp features in the primordial spectra within the framework of effective field theory of inflation, wherein curvature perturbations are the consequence…
Consistently violating the non-Gaussian consistency relation
Sander Mooij, Gonzalo A. Palma
Non-attractor models of inflation are characterized by the super-horizon evolution of curvature perturbations, introducing a violation of the non-Gaussian consistency relation betw…
