Fossilized Gravitational Wave Relic and Primordial Clocks
Suddhasattwa Brahma, Elliot Nelson, Sarah Shandera
If long wavelength primordial tensor modes are coupled to short wavelength scalar modes, the scalar curvature two-point function will have an off-diagonal component. This `fossil'…
Cosmic Variance of the Spectral Index from Mode Coupling
Joseph Bramante, Jason Kumar, Elliot Nelson +1
We demonstrate that local, scale-dependent non-Gaussianity can generate cosmic variance uncertainty in the observed spectral index of primordial curvature perturbations. In a unive…
Non-Gaussian Mode Coupling and the Statistical Cosmological Principle
Marilena LoVerde, Elliot Nelson, Sarah Shandera
Local-type primordial non-Gaussianity couples statistics of the curvature perturbation ζon vastly different physical scales. Because of this coupling, statistics (i.e. the polyspec…
