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…
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…
Inflationary Initial Conditions for the Cosmological Gravitational Wave Background
Lorenzo Valbusa Dall'Armi, Alina Mierna, Sabino Matarrese +1
The initial conditions on the anisotropies of the stochastic gravitational-wave background of cosmological origin (CGWB) largely depend on the mechanism that generates the gravitat…
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…
