Exploring Gravitational Wave Signatures Due to Primordial Non-gaussianity and Large Scale Structure Using SKAO
H. V. Ragavendra, Giulia Capurri, Alina Mierna +8
This chapter explores theoretical and observational strategies to use the stochastic gravitational-wave background detectable by Square Kilometre Array Observatory (SKAO) as a prob…
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…
Adiabatic or Non-Adiabatic? Unraveling the Nature of Initial Conditions in the Cosmological Gravitational Wave Background
Lorenzo Valbusa Dall'Armi, Alina Mierna, Sabino Matarrese +1
The non-thermal nature of the cosmological gravitational wave background (CGWB) makes it difficult to define the initial condition for the graviton distribution, which determines t…
Non-linear effects on the Cosmological Gravitational Wave Background anisotropies
Alina Mierna, Sabino Matarrese, Nicola Bartolo +1
The Cosmological Gravitational Wave Background (CGWB) anisotropies contain valuable information about the physics of the early universe. Given that General Relativity is intrinsica…
