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…
Constraints on inflation with LSS surveys: features in the primordial power spectrum
Gonzalo A. Palma, Domenico Sapone, Spyros Sypsas
We analyse the efficiency of future large scale structure surveys to unveil the presence of scale dependent features in the primordial spectrum --resulting from cosmic inflation--…
Shapes and features of the primordial bispectrum
Jinn-Ouk Gong, Gonzalo A. Palma, Spyros Sypsas
If time-dependent disruptions from slow-roll occur during inflation, the correlation functions of the primordial curvature perturbation should have scale-dependent features, a case…
Axion excursions of the landscape during inflation
Gonzalo A. Palma, Walter Riquelme
Because of their quantum fluctuations, axion fields had a chance to experience field excursions traversing many minima of their potentials during inflation. We study this situation…
