Detecting primordial features with LISA
Jacopo Fumagalli, Mauro Pieroni, Sébastien Renaux-Petel +1
Oscillations in the frequency profile of the stochastic gravitational wave background are a characteristic prediction of small-scale features during inflation. In this paper we pre…
Primordial gravitational waves from excited states
Jacopo Fumagalli, Gonzalo A. Palma, Sébastien Renaux-Petel +3
We show that a scalar excited state with large occupation numbers during inflation leads to an enhancement of tensor modes and a characteristic pattern of order-one oscillations in…
Expansion history-dependent oscillations in the scalar-induced gravitational wave background
Lukas T. Witkowski, Guillem Domènech, Jacopo Fumagalli +1
Oscillations in the frequency profile of the scalar-induced contribution to the stochastic gravitational wave background are a characteristic signal for small-scale features during…
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…
