Inflationary dynamics of kinetically-coupled gauge fields
Ricardo Z. Ferreira, Jonathan Ganc
We investigate the inflationary dynamics of two kinetically-coupled massless gauge fields with time-varying kinetic-term coefficients. Ensuring that the system does not have…
Probing correlations of early magnetic fields using mu-distortion
Jonathan Ganc, Martin S. Sloth
The damping of a non-uniform magnetic field between the redshifts of about and injects energy into the photon-baryon plasma and causes the CMB to deviate from a perfe…
Scale-dependent bias of galaxies and mu-type distortion of the cosmic microwave background spectrum from single-field inflation with a modified initial state
Jonathan Ganc, Eiichiro Komatsu
We investigate the phenomenological consequences of a modification of the initial state of a single inflationary field. While single-field inflation with the standard Bunch-Davies…
Calculating the local-type fNL for slow-roll inflation with a non-vacuum initial state
Jonathan Ganc
Single-field slow-roll inflation with a non-vacuum initial state has an enhanced bispectrum in the local limit. We numerically calculate the local-type fNL signal in the CMB that w…
A new method for calculating the primordial bispectrum in the squeezed limit
Jonathan Ganc, Eiichiro Komatsu
In 2004, Creminelli and Zaldarriaga proposed a consistency relation for the primordial curvature perturbation of all single-field inflation models; it related the bispectrum in the…
