How Well Do We Know the Scalar-Induced Gravitational Waves?
A. J. Iovino, S. Matarrese, G. Perna +2
Gravitational waves sourced by amplified scalar perturbations are a common prediction across a wide range of cosmological models. These scalar curvature fluctuations are inherently…
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…
Curbing PBHs with PTAs
A. J. Iovino, G. Perna, A. Riotto +1
Sizeable primordial curvature perturbations needed to seed a population of primordial black holes (PBHs) will be accompanied by a scalar-induced gravitational wave signal that can…
Investigating the impact of galaxies' compact binary hosting probability for gravitational-wave cosmology
Gabriele Perna, Simone Mastrogiovanni, Angelo Ricciardone
With the advent of future-generation interferometers a huge number of Gravitational Wave (GW) signals is expected to be measured without an electromagnetic counterpart. Although th…
Fully non-Gaussian Scalar-Induced Gravitational Waves
Gabriele Perna, Chiara Testini, Angelo Ricciardone +1
Scalar-induced Gravitational Waves (SIGWs) represent a particular class of primordial signals which are sourced at second-order in perturbation theory whenever a scalar fluctuation…
