Tensor non-Gaussianities from Non-minimal Coupling to the Inflaton
Emanuela Dimastrogiovanni, Matteo Fasiello, Gianmassimo Tasinato +1
Tensor non-Gaussianity represents an important future probe of the physics of inflation. Inspired by recent works, we elaborate further on the possibility of significant primordial…
Primordial gravitational wave phenomenology with polarized Sunyaev Zel'dovich tomography
Anne-Sylvie Deutsch, Emanuela Dimastrogiovanni, Matteo Fasiello +2
The detection and characterization of primordial gravitational waves through their impact on the polarization anisotropies of the cosmic microwave background (CMB) is a primary sci…
Non-Gaussianity from Axion-Gauge Fields Interactions during Inflation
Emanuela Dimastrogiovanni, Matteo Fasiello, Robert J. Hardwick +3
We study the scalar-tensor-tensor non-Gaussian signal in an inflationary model comprising also an axion coupled with SU(2) gauge fields. In this set-up, metric fluctuations are sou…
Probing the inflationary particle content: extra spin-2 field
Emanuela Dimastrogiovanni, Matteo Fasiello, Gianmassimo Tasinato
We study how inflationary observables associated with primordial tensor modes are affected by coupling the minimal field content with an extra spin-2 particle during inflation. We…
CMB Spectral Distortions from Cooling Macroscopic Dark Matter
Saurabh Kumar, Emanuela Dimastrogiovanni, Glenn D. Starkman +2
We propose a new mechanism by which dark matter (DM) can affect the early universe. The hot interior of a macroscopic DM, or macro, can behave as a heat reservoir so that energetic…
