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…
Exploring Evaporating Primordial Black Holes with Gravitational Waves
Guillem Domènech, Volodymyr Takhistov, Misao Sasaki
Primordial black holes (PBHs) from the early Universe have been connected with the nature of dark matter and can significantly affect cosmological history. We show that coincidence…
Probing non-Gaussianities with the high frequency tail of induced gravitational waves
Vicente Atal, Guillem Domènech
We investigate in detail the spectrum of gravitational waves induced by a peaked primordial curvature power spectrum generated in single field inflationary models. We argue that th…
