Loop-Induced Stochastic Bias at Small Wavevectors
Michael McAneny, Alexander K. Ridgway, Mikhail P. Solon +1
Primordial non-Gaussianities enhanced at small wavevectors can induce a power spectrum of the galaxy overdensity that differs greatly from that of the matter overdensity at large l…
Bound states and the classical double copy
Walter D. Goldberger, Alexander K. Ridgway
We extend the perturbative classical double copy to the analysis of bound systems. We first obtain the leading order perturbative gluon radiation field sourced by a system of inter…
Non-Gaussian Enhancements of Galactic Halo Correlations in Quasi-Single Field Inflation
Haipeng An, Michael McAneny, Alexander K. Ridgway +1
We consider a quasi-single field inflation model in which the inflaton interacts with a massive scalar field called the isocurvaton. Due to the breaking of time translational invar…
Quasi Single Field Inflation in the non-perturbative regime
Haipeng An, Michael McAneny, Alexander K. Ridgway +1
In quasi single field inflation there are massive fields that interact with the inflaton field. If these other fields are not much heavier than the Hubble constant during inflation…
