Constraining primordial non-Gaussianity and parity-violation through Scalar-Induced Gravitational Waves with next-generation ground-based interferometers
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 generation gravitational wave detectors. We develop a framework that accounts for contributions to the energy density spectrum of GWs arising from the scalar non Gaussianity quantified by bispectrum and trispectrum, and perform parameter ...
