CMB Spectral Distortion Anisotropies from Acoustic Damping with primordial non-Gaussianity
Jens Chluba, Atsuhisa Ota, Nicola Bartolo
In this paper, we evaluate the precise distortion source and transfer functions caused by mixing of blackbodies of different temperatures using the recently developed frequency hie…
Constraining primordial non-Gaussianity and parity-violation through Scalar-Induced Gravitational Waves with next-generation ground-based interferometers
Ilaria Caporali, H. V. Ragavendra, Angelo Ricciardone +1
In this work, we investigate the prospects for probing primordial non-Gaussianity and associated symmetry of parity through scalar-induced gravitational waves (SIGWs), with third-g…
Inflationary Fossils Beyond Perturbation Theory
Riccardo Impavido, Nicola Bartolo
In this work we provide the missing link between two approaches aimed at characterizing the effect of long perturbation modes in Inflation. We consider the Inflationary Fossils' ap…
Gravitational-wave lensing beyond rays: a disordered-system approach
Ripalta Amoruso, Ginevra Braga, Alice Garoffolo +3
We develop a framework to describe gravitational wave propagation through a stochastic distribution of weak gravitational lenses beyond the geometric optics limit. We model the len…
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…
Charged Black-Hole Binary Evolution at Second Post-Newtonian Order
Andrea Placidi, Elisa Grilli, Marta Orselli +3
We study the dynamics of electrically charged black-hole binaries and their gravitational-wave emission during the inspiral phase. Within the post-Newtonian framework, we derive th…
