| dc.description.abstract | Cosmological perturbations due to statistical thermal fluctuations in a single fluid characterized by an arbitrary equation of state are computed. Formulas to predict the scalar and tensor perturbation spectra and non-Gaussianity parameters at a given temperature are derived. These results are relevant to cosmological scenarios, such as cyclic or emergent universes, where cosmic structures may have been seeded thermally instead of originating purely from quantum vacuum fluctuations.
