Degeneracy between primordial tensors modes and cosmic strings in future CMB data from the Planck satellite
journal contribution
posted on 2023-06-07, 23:18 authored by Jon Urrestilla, Pia Mukherjee, Andrew R Liddle, Neil Bevis, Mark HindmarshMark Hindmarsh, Martin KunzWhile observations indicate that the predominant source of cosmic inhomogeneities are adiabatic perturbations, there are a variety of candidates to provide auxiliary trace effects, including inflation-generated primordial tensors and cosmic defects which both produce B-mode cosmic microwave background polarization. We investigate whether future experiments may suffer confusion as to the true origin of such effects, focusing on the ability of Planck to distinguish tensors from cosmic strings, and show that there is no significant degeneracy.
