Understanding the Nature of Scalar-Induced Gravitational Waves
A. J. Iovino, G. Perna, D. Perrone +2
We offer a physical interpretation of the origin of the scalar-induced gravitational wave background, showing that it is mainly produced around the peaks of the scalar perturbation…
Quantum production of gravitational waves after inflation
Alina Mierna, Gabriele Perna, Sabino Matarrese +2
A variety of mechanisms in the early Universe lead to the generation of gravitational waves (GWs). We introduce here a novel source of GWs generated by vacuum fluctuations after in…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Deciphering the Instability of the Black Hole Ringdown Quasinormal Spectrum
A. Ianniccari, A. J. Iovino, A. Kehagias +4
The spectrum of the quasinormal modes of the gravitational waves emitted during the ringdown phase following the merger of two black holes is of primary importance in gravitational…
