Reconstructing Primordial Curvature Perturbations via Scalar-Induced Gravitational Waves with LISA
Jonas El Gammal, Aya Ghaleb, Gabriele Franciolini +17
Many early universe scenarios predict an enhancement of scalar perturbations at scales currently unconstrained by cosmological probes. These perturbations source gravitational wave…
Snowmass Theory Frontier: Astrophysics and Cosmology
Daniel Green, Joshua T. Ruderman, Benjamin R. Safdi +84
We summarize progress made in theoretical astrophysics and cosmology over the past decade and areas of interest for the coming decade. This Report is prepared as the TF09 "Astrophy…
Resonant features in the stochastic gravitational wave background
Jacopo Fumagalli, Sébastien Renaux-Petel, Lukas T. Witkowski
We analyse the post-inflationary contribution to the stochastic gravitational wave background due to a resonant feature in the scalar power spectrum, which is characterised by an o…
Oscillations in the stochastic gravitational wave background from sharp features and particle production during inflation
Jacopo Fumagalli, Sébastien Renaux-Petel, Lukas T. Witkowski
We identify a characteristic pattern in the scalar-induced stochastic gravitational wave background from particle production during inflation. If particle production is sufficientl…
Matching and running sensitivity in non-renormalizable inflationary models
Jacopo Fumagalli, Marieke Postma, Melvin van den Bout
Most of the inflationary models that are in agreement with the Planck data rely on the presence of non-renormalizable operators. If the connection to low energy particle physics is…
Higgs vacuum (in)stability during inflation: the dangerous relevance of de Sitter departure and Planck-suppressed operators
Jacopo Fumagalli, Sébastien Renaux-Petel, John W. Ronayne
The measured Standard Model parameters lie in a range such that the Higgs potential, once extrapolated up to high scales, develops a minimum of negative energy density. This has im…
