Gravitational Axiverse Spectroscopy: Seeing the Forest for the Axions
Ema Dimastrogiovanni, Matteo Fasiello, Jacob M. Leedom +2
We consider inflationary models with multiple spectator axions coupled to dark gauge sectors via Chern-Simons (CS) terms. The energy injection into Abelian gauge fields from the ax…
Enhancing Bispectrum Estimators for Galaxy Redshift Surveys with Velocities
Julius Wons, Emanuela Dimastrogiovanni, Matteo Fasiello +2
We forecast the ability of bispectrum estimators to constrain primordial non-Gaussianity using future photometric galaxy redshift surveys. A full-sky survey with photometric redshi…
Primordial Gravitational Waves in non-Minimally Coupled Chromo-Natural Inflation
Ema Dimastrogiovanni, Matteo Fasiello, Martino Michelotti +1
We consider inflation driven by an axion-like particle coupled to an SU(2) gauge sector via a Chern-Simons term. Known as chromo-natural inflation, this scenario is in tension with…
