Primordial Non-Gaussianity in Supersolid Inflation
Marco Celoria, Denis Comelli, Luigi Pilo +1
We study primordial non-gaussianity in supersolid inflation. The dynamics of supersolid is formulated in terms of an effective field theory based on four scalar fields with a shift…
Beyond Perturbation Theory in Inflation
Marco Celoria, Paolo Creminelli, Giovanni Tambalo +1
Inflationary perturbations are approximately Gaussian and deviations from Gaussianity are usually calculated using in-in perturbation theory. This method, however, fails for unlike…
Boosting GWs in Supersolid Inflation
Marco Celoria, Denis Comelli, Luigi Pilo +1
Inflation driven by a generic self-gravitating medium is an interesting alternative to study the impact of spontaneous spacetime symmetry breaking during a quasi de-Sitter phase, i…
Prospects for Fundamental Physics with LISA
Enrico Barausse, Emanuele Berti, Thomas Hertog +318
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental…
Primordial Non-Gaussianity
Marco Celoria, Sabino Matarrese
Here we review the present status of modelling of and searching for primordial non-Gaussianity of cosmological perturbations. After introducing the models for non-Gaussianity gener…
Lecture notes on black hole binary astrophysics
Marco Celoria, Roberto Oliveri, Alberto Sesana +1
We describe some key astrophysical processes driving the formation and evolution of black hole binaries of different nature, from stellar-mass to supermassive systems. In the first…
