Observational Constraints on Constant Roll Inflation
Jose T. Galvez Ghersi, Alex Zucca, Andrei V. Frolov
Constant-roll inflation was recently introduced by Motohashi, Starobinsky and Yokoyama as a phenomenological way to parametrize deviations from the slow-roll scenarios. In this pap…
Evolution of dark energy reconstructed from the latest observations
Yuting Wang, Levon Pogosian, Gong-Bo Zhao +1
We reconstruct evolution of the dark energy (DE) density using a nonparametric Bayesian approach from a combination of latest observational data. We caution against parameterizing…
Searching for Primordial Magnetic Fields with CMB B-modes
Levon Pogosian, Alex Zucca
Was the primordial universe magnetized? The answer to this question would help explain the origin of micro-Gauss strength magnetic fields observed in galaxies. It is also of fundam…
